Diesel fuel , also called diesel oil , heavy oil (historically) or simply diesel , is a liquid fuel specifically designed for use in a diesel engine , a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics.

124-488: Neste Oyj (international name: Neste Corporation ; former names Neste Oil Corporation and Fortum Oil and Gas Oy ; Finnish pronunciation: [ˈneste] ) is an oil refining and marketing company located in Espoo , Finland . It produces, refines and markets oil products, provides engineering services, and licenses production technologies. Neste has operations in 14 countries. Neste shares are listed on

248-402: A devolatilization process to separate usable oil from the waste asphaltene material. Certain cracked streams are particularly suitable to produce petrochemicals includes polypropylene, heavier polymers, and block polymers based on the molecular weight and the characteristics of the olefin specie that is cracked from the source feedstock. Oil refineries are large-scale plants, processing about

372-632: A broad range of several applications. Once separated and purified of any contaminants and impurities, the fuel or lubricant can be sold without further processing. Smaller molecules such as isobutane and propylene or butylenes can be recombined to meet specific octane requirements by processes such as alkylation , or more commonly, dimerization . The octane grade of gasoline can also be improved by catalytic reforming , which involves removing hydrogen from hydrocarbons producing compounds with higher octane ratings such as aromatics . Intermediate products such as gasoils can even be reprocessed to break

496-761: A capacity of 940,000 bbl/d (149,000 m /d) but effective run rates have been dramatically lower due to the impact of 20 years of sanctions , and SK Energy 's Ulsan in South Korea with 840,000 bbl/d (134,000 m /d) are the second and third largest, respectively. Prior to World War II in the early 1940s, most petroleum refineries in the United States consisted simply of crude oil distillation units (often referred to as atmospheric crude oil distillation units). Some refineries also had vacuum distillation units as well as thermal cracking units such as visbreakers (viscosity breakers, units to lower

620-425: A diesel fuel. A higher cetane number indicates that the fuel ignites more readily when sprayed into hot compressed air. European (EN 590 standard) road diesel has a minimum cetane number of 51. Fuels with higher cetane numbers, normally "premium" diesel fuels with additional cleaning agents and some synthetic content, are available in some markets. About 86.1% of diesel fuel mass is carbon, and when burned, it offers

744-537: A few minutes due to coal dust deposition. Before diesel fuel was standardised, diesel engines typically ran on cheap fuel oils. In the United States, these were distilled from petroleum, whereas in Europe, coal-tar creosote oil was used. Some diesel engines were fuelled with mixtures of fuels, such as petrol, kerosene, rapeseed oil, or lubricating oil which were cheaper because, at the time, they were not being taxed. The introduction of motor-vehicle diesel engines, such as

868-800: A few percent sulfur -containing molecules, elemental sulfur is also often produced as a petroleum product. Carbon , in the form of petroleum coke , and hydrogen may also be produced as petroleum products. The hydrogen produced is often used as an intermediate product for other oil refinery processes such as hydrocracking and hydrodesulfurization . Petroleum products are usually grouped into four categories: light distillates (LPG, gasoline, naphtha), middle distillates (kerosene, jet fuel, diesel), heavy distillates, and residuum (heavy fuel oil, lubricating oils, wax, asphalt). These require blending various feedstocks, mixing appropriate additives, providing short-term storage, and preparation for bulk loading to trucks, barges, product ships, and railcars. This classification

992-469: A gel at temperatures of −19 to −15 °C (−2 to 5 °F), that cannot flow in fuel systems. Conventional diesel fuels vaporise at temperatures between 149 °C and 371 °C. Conventional diesel flash points vary between 52 and 96 °C, which makes it safer than petrol and unsuitable for spark-ignition engines. Unlike petrol, the flash point of a diesel fuel has no relation to its performance in an engine nor to its auto ignition qualities. As

1116-496: A good approximation the chemical formula of diesel is C n H 2n . Diesel is a mixture of different molecules. As carbon has a molar mass of 12 g/mol and hydrogen has a molar mass of about 1 g/mol, so the fraction by weight of carbon in EN ;590 diesel fuel is roughly 12/14. The reaction of diesel combustion is given by: 2 C n H 2n + 3n O 2 ⇌ 2n CO 2 + 2n H 2 O Carbon dioxide has

1240-428: A heavy, long-chained oil into a lighter short-chained one, by various forms of cracking such as fluid catalytic cracking , thermal cracking , and hydrocracking . The final step in gasoline production is the blending of fuels with different octane ratings, vapor pressures , and other properties to meet product specifications. Another method for reprocessing and upgrading these intermediate products (residual oils) uses

1364-418: A hundred end-products. In 2017, Neste was the world's largest producer of renewable diesel, producing 2.6 million tonnes per year. Neste has developed the proprietary NEXBTL technology for the production of renewable fuels . Renewable diesel is a hydrodeoxygenated paraffinic fuel, which can be used in conventional diesel engines without engine modifications. Neste's sustainable aviation fuel (SAF)

1488-430: A hundred thousand to several hundred thousand barrels of crude oil a day. Because of the high capacity, many of the units operate continuously , as opposed to processing in batches , at steady state or nearly steady state for months to years. The high capacity also makes process optimization and advanced process control very desirable. Petroleum products are materials derived from crude oil ( petroleum ) as it

1612-633: A joint venture to research the production of renewable diesel oil from wood biomass through biomass gasification and the Fischer-Tropsch process in Varkaus , Finland. However, coming second in a bid for European Investment Bank startup funding led to the cancellation of this project in 2012. Neste's self-service station chain in Poland was sold to Royal Dutch Shell in April 2013. In 2015

1736-645: A large amount of steam and cooling water need to have an abundant source of water. Oil refineries, therefore, are often located nearby navigable rivers or on a seashore, nearby a port. Such location also gives access to transportation by river or by sea. The advantages of transporting crude oil by pipeline are evident, and oil companies often transport a large volume of fuel to distribution terminals by pipeline. A pipeline may not be practical for products with small output, and railcars, road tankers, and barges are used. Petrochemical plants and solvent manufacturing (fine fractionating) plants need spaces for further processing of

1860-658: A large volume of refinery products, or to mix chemical additives with a product at source rather than at blending terminals. The refining process releases a number of different chemicals into the atmosphere (see AP 42 Compilation of Air Pollutant Emission Factors ) and a notable odor normally accompanies the presence of a refinery. Aside from air pollution impacts there are also wastewater concerns, risks of industrial accidents such as fire and explosion, and noise health effects due to industrial noise . Many governments worldwide have mandated restrictions on contaminants that refineries release, and most refineries have installed

1984-472: A means of separating the fission product palladium from PUREX raffinate which comes from used nuclear fuel . In this system of solvent extraction, the hydrocarbons of the diesel act as the diluent while the di alkyl sulfides act as the extractant. This extraction operates by a solvation mechanism. So far, neither a pilot plant nor full scale plant has been constructed to recover palladium, rhodium or ruthenium from nuclear wastes created by

2108-615: A molar mass of 44g/mol as it consists of 2 atoms of oxygen (16 g/mol) and 1 atom of carbon (12 g/mol). So 12 g of carbon yield 44 g of Carbon dioxide. Diesel has a density of 0.838 kg per liter. Putting everything together the mass of carbon dioxide that is produced by burning 1 liter of diesel fuel can be calculated as: 0.838 k g / L ⋅ 12 14 ⋅ 44 12 = 2.63 k g / L {\displaystyle 0.838kg/L\cdot {\frac {12}{14}}\cdot {\frac {44}{12}}=2.63kg/L} The figure obtained with this estimation

2232-608: A net heating value of 43.1 MJ/kg as opposed to 43.2 MJ/kg for gasoline. Due to the higher density, diesel fuel offers a higher volumetric energy density: the density of EN 590 diesel fuel is defined as 0.820 to 0.845 kg/L (6.84 to 7.05 lb/US gal) at 15 °C (59 °F), about 9.0-13.9% more than EN 228 gasoline (petrol)'s 0.720–0.775 kg/L (6.01–6.47 lb/US gal) at 15 °C, which should be put into consideration when comparing volumetric fuel prices. The CO 2 emissions from diesel are 73.25 g/MJ, just slightly lower than for gasoline at 73.38 g/MJ. Diesel fuel

2356-462: A number of further chemical processes are integrated into it. For example, light hydrocarbons are steam-cracked in an ethylene plant, and the produced ethylene is polymerized to produce polyethene . To ensure both proper separation and environmental protection, a very low sulfur content is necessary in all but the heaviest products. The crude sulfur contaminant is transformed to hydrogen sulfide via catalytic hydrodesulfurization and removed from

2480-402: A recent transfer to ultra-low-sulfur diesel (ULSD), which causes infrastructural complications. In Sweden, a diesel fuel designated as MK-1 (class 1 environmental diesel) is also being sold. This is a ULSD that also has a lower aromatics content, with a limit of 5%. This fuel is slightly more expensive to produce than regular ULSD. In Germany, the fuel tax on diesel fuel is about 28% lower than

2604-524: A reduced-tax agricultural-only product containing an identifying coloured dye known as red diesel . The official term for white diesel is DERV , standing for diesel-engine road vehicle . In Australia , diesel fuel is also known as distillate (not to be confused with "distillate" in an older sense referring to a different motor fuel), and in Indonesia (as well in Israel ), it is known as Solar ,

2728-562: A research program on algae , but this was discontinued in 2015. In 2019, the research program restarted to investigate the production of aviation fuel from algae and municipal solid waste . In 2008, Rinne retired, with Matti Lievonen succeeding him as CEO. In 2011, a plant similar in size to the Singapore plant was launched in Rotterdam , Netherlands . Its investment costs amounted to 670 million euros. Neste and Stora Enso ran

2852-551: A shoreline necklace of refineries, built in the early 20th century before this area was populated, and associated chemical plants are adjacent to urban areas in Richmond , Martinez , Pacheco , Concord , Pittsburg , Vallejo and Benicia , with occasional accidental events that require " shelter in place " orders to the adjacent populations. A number of refineries are located in Sherwood Park, Alberta , directly adjacent to

2976-427: A trademarked name from the country's national petroleum company Pertamina . The term gas oil (French: gazole ) is sometimes also used to refer to diesel fuel. Diesel fuel originated from experiments conducted by German scientist and inventor Rudolf Diesel for his compression-ignition engine which he invented around 1892. Originally, Diesel did not consider using any specific type of fuel. Instead, he claimed that

3100-437: Is C 12 H 23 , ranging approximately from C 10 H 20 to C 15 H 28 . Most diesel fuels freeze at common winter temperatures, while the temperatures greatly vary. Petrodiesel typically freezes around temperatures of −8.1 °C (17.4 °F), whereas biodiesel freezes between temperatures of 2 to 15 °C (36 to 59 °F). The viscosity of diesel noticeably increases as the temperature decreases, changing it into

3224-680: Is a drop-in fuel, which can be mixed with kerosene to produce a mixture that contains at least 50% kerosene. Among others, it is used by Lufthansa and the Swedish Air BP . In 2019, Neste produced about 100,000 tonnes of sustainable aviation fuel and plans to produce around 1.5 million tonnes per year by 2023. Neste owns a chain of service stations , which is the largest in Finland. In 2020, Neste had station chains consisting of more than 800 traffic and automatic stations in Finland, Estonia , Latvia and Lithuania . As of 31 May 2022,

3348-544: Is an industrial process plant where petroleum (crude oil) is transformed and refined into products such as gasoline (petrol), diesel fuel , asphalt base , fuel oils , heating oil , kerosene , liquefied petroleum gas and petroleum naphtha . Petrochemical feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant . [1] There

3472-446: Is available in some countries for use primarily in agricultural applications, such as fuel for tractors, recreational and utility vehicles or other noncommercial vehicles that do not use public roads . This fuel may have sulfur levels that exceed the limits for road use in some countries (e.g. US). This untaxed diesel is dyed red for identification, and using this untaxed diesel fuel for a typically taxed purpose (such as driving use),

3596-433: Is based on the way crude oil is distilled and separated into fractions. Over 6,000 items are made from petroleum waste by-products, including fertilizer , floor coverings , perfume , insecticide , petroleum jelly , soap , vitamin capsules . The image below is a schematic flow diagram of a typical oil refinery that depicts the various unit processes and the flow of intermediate product streams that occurs between

3720-476: Is because diesel engines are more fuel efficient, and diesel fuel is less prone to catching fire. Some of these diesel-powered vehicles (such as the Leopard 1 or MAN 630 ) still ran on petrol, and some military vehicles were still made with otto engines (e. g. Ural-375 or Unimog 404 ), incapable of running on diesel fuel. Today's tractors and heavy equipment are mostly diesel-powered. Among tractors, only

3844-577: Is close to the values found in the literature. For gasoline, with a density of 0.75 kg/L and a ratio of carbon to hydrogen atoms of about 6 to 14, the estimated value of carbon emission if 1 liter of gasoline is burnt gives: 0.75 k g / L ⋅ 6 ⋅ 12 6 ⋅ 12 + 14 ⋅ 1 ⋅ 44 12 = 2.3 k g / L {\displaystyle 0.75kg/L\cdot {{\frac {6\cdot 12}{6\cdot 12+14}}\cdot 1}\cdot {\frac {44}{12}}=2.3kg/L} In

3968-408: Is cooled by exchanging heat with the incoming crude oil. All of the fractions (i.e., the overhead naphtha, the sidecuts, and the bottom residue) are sent to intermediate storage tanks before being processed further. A party searching for a site to construct a refinery or a chemical plant needs to consider the following issues: Factors affecting site selection for oil refinery: Refineries that use

4092-443: Is dictated by the particular composition of and storage plans for diesel fuels. Each is added at the 5-50 ppm level. The diesel engine is a multifuel engine and can run on a huge variety of fuels. However, development of high-performance, high-speed diesel engines for cars and lorries in the 1930s meant that a proper fuel specifically designed for such engines was needed: diesel fuel. In order to ensure consistent quality, diesel fuel

4216-588: Is generally simpler to refine from petroleum than gasoline Additional refining is required to remove sulfur, which contributes to a sometimes higher cost. In many parts of the United States and throughout the United Kingdom and Australia, diesel fuel may be priced higher than petrol per gallon or litre . Reasons for higher-priced diesel include the shutdown of some refineries in the Gulf of Mexico , diversion of mass refining capacity to gasoline production, and

4340-502: Is little need for using diesel fuel in aircraft, and diesel fuel is not commercially used as aviation fuel. Instead, petrol ( Avgas ), and jet fuel (e. g. Jet A-1) are used. However, especially in the 1920s and 1930s, numerous series-production aircraft diesel engines that ran on fuel oils were made, because they had several advantages: their fuel consumption was low, they were reliable, not prone to catching fire, and required minimal maintenance. The introduction of petrol direct injection in

4464-473: Is mainly paraffins with low sulfur and aromatics content. This material is blended often into the above mentions petroleum derived diesel. Biodiesel is obtained from vegetable oil or animal fats (bio lipids ) which are mainly fatty acid methyl esters (FAME), and transesterified with methanol . It can be produced from many types of oils, the most common being rapeseed oil (rapeseed methyl ester, RME) in Europe and soybean oil (soy methyl ester, SME) in

4588-424: Is processed in oil refineries . The majority of petroleum is converted to petroleum products, which includes several classes of fuels. Oil refineries also produce various intermediate products such as hydrogen , light hydrocarbons, reformate and pyrolysis gasoline . These are not usually transported but instead are blended or processed further on-site. Chemical plants are thus often adjacent to oil refineries or

4712-493: Is produced from various sources, the most common being petroleum . Other sources include biomass , animal fat , biogas , natural gas , and coal liquefaction . Petroleum diesel is the most common type of diesel fuel. It is produced by the fractional distillation of crude oil between 200 and 350 °C (392 and 662 °F) at atmospheric pressure , resulting in a mixture of carbon chains that typically contain between 9 and 25 carbon atoms per molecule . This fraction

4836-413: Is removed from the distillation column by a pumparound system as shown in the diagram below. As shown in the flow diagram, the overhead distillate fraction from the distillation column is naphtha. The fractions removed from the side of the distillation column at various points between the column top and bottom are called sidecuts . Each of the sidecuts (i.e., the kerosene, light gas oil, and heavy gas oil)

4960-471: Is sometimes called petrodiesel in some academic circles. Diesel is a high-volume product of oil refineries. In many countries, diesel fuel is standardized. For example, in the European Union, the standard for diesel fuel is EN 590 . Ultra-low-sulfur diesel (ULSD) is a diesel fuel with substantially lowered sulfur contents. As of 2016, almost all of the petroleum-based diesel fuel available in

5084-421: Is standardised; the first standards were introduced after World War II. Typically, a standard defines certain properties of the fuel, such as cetane number , density , flash point , sulphur content, or biodiesel content. Diesel fuel standards include: Diesel fuel Biodiesel fuel The principal measure of diesel fuel quality is its cetane number . A cetane number is a measure of the delay of ignition of

5208-689: Is still in widespread use in certain regions. During development of rocket engines in Germany during World War II J-2 Diesel fuel was used as the fuel component in several engines including the BMW 109-718 . J-2 diesel fuel was also used as a fuel for gas turbine engines. In the United States, petroleum-derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffins including n , iso , and cycloparaffins ), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes ). The average chemical formula for common diesel fuel

5332-414: Is subjected to hydrodesulfurization . Usually such "straight-run" diesel is insufficient in supply and quality, so other sources of diesel fuels are blended in. One major source of additional diesel fuel is obtained by cracking heavier fractions, using visbreaking and coking. This technology converts less useful fractions but the product contains olefins ( alkenes ) which require hydrogenation to give

5456-475: Is then processed further in the other refinery processing units. The CDU is often referred to as the atmospheric distillation unit because it operates at slightly above atmospheric pressure. Below is a schematic flow diagram of a typical crude oil distillation unit. The incoming crude oil is preheated by exchanging heat with some of the hot, distilled fractions and other streams. It is then desalted to remove inorganic salts (primarily sodium chloride). Following

5580-480: Is thus suited for certain (but not all) diesel engines. Until World War II, several military vehicles, especially those that required high engine performance ( armored fighting vehicles , for example the M26 Pershing or Panther tanks), used conventional otto engines and ran on petrol. Ever since World War II, several military vehicles with diesel engines have been made, capable of running on diesel fuel. This

5704-520: Is used in the UK as a synonym for unmarked road diesel fuel. In India, taxes on diesel fuel are lower than on petrol, as the majority of the transportation for grain and other essential commodities across the country runs on diesel. Taxes on biodiesel in the US vary between states. Some states (Texas, for example) have no tax on biodiesel and a reduced tax on biodiesel blends equivalent to the amount of biodiesel in

5828-590: Is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. In 2020, the total capacity of global refineries for crude oil was about 101.2 million barrels per day. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units, such as distillation columns. In many ways, oil refineries use many different technologies and can be thought of as types of chemical plants . Since December 2008,

5952-648: The Allies , during the Oil Campaign of World War II . Another close contender for the title of hosting the world's oldest oil refinery is Salzbergen in Lower Saxony , Germany. Salzbergen's refinery was opened in 1860. At one point, the refinery in Ras Tanura , Saudi Arabia owned by Saudi Aramco was claimed to be the largest oil refinery in the world. For most of the 20th century, the largest refinery

6076-619: The Edeleanu process . This increased the refining efficiency compared to pure fractional distillation and allowed a massive development of the refining plants. Successively, the process was implemented in France, Germany, U.S. and in a few decades became worldwide spread. In 1910 Edeleanu founded "Allgemeine Gesellschaft für Chemische Industrie" in Germany, which, given the success of the name, changed to Edeleanu GmbH, in 1930. During Nazi's time,

6200-531: The Mercedes-Benz OM 138 , in the 1930s meant that higher-quality fuels with proper ignition characteristics were needed. At first no improvements were made to motor-vehicle diesel fuel quality. After World War II, the first modern high-quality diesel fuels were standardised. These standards were, for instance, the DIN 51601, VTL 9140–001, and NATO F 54 standards. In 1993, the DIN 51601 was rendered obsolete by

6324-674: The Nasdaq Helsinki . As of 2022, the Prime Minister's Office of Finland is the largest shareholder in the company, owning 35.91% of shares. In 2021, Neste was the third largest company in Finland in terms of revenue . The name "Neste" means "liquid" in Finnish . Neste was founded in 1948 as the State petrol company of Finland with the purpose to ensure the availability of refined fuels in Finland. The company's headquarters

6448-469: The Stirling engine , or boilers for steam engines . Diesel is often used in heavy trucks . However, diesel exhaust , especially from older engines, can cause health damage. Diesel fuel has many colloquial names; most commonly, it is simply referred to as diesel . In the United Kingdom, diesel fuel for road use is commonly called diesel or sometimes white diesel if required to differentiate it from

6572-676: The food industry , waste and residues from vegetable oil production, technical corn oil , palm oil, rapeseed oil , and soybean oil . About 80% of renewable feedstock is waste and residue fats and oils. Neste also researches the use of community waste, algae, lignocellulose , and liquefied waste plastic as feedstock. In 2019, most of the crude oil used by Neste came from Russia. Neste produces gasolines , diesel , aviation and marine fuels , light and heavy fuel oils, base oils, gasoline components, special fuels and solvents. LPGs, carbon dioxide , and sulfur are sold as by-products. Neste's products include dozens of types of gasoline and more than

6696-493: The hydrocarbons to be separated by distillation . Since the lighter liquid products are in great demand for use in internal combustion engines, a modern refinery will convert heavy hydrocarbons and lighter gaseous elements into these higher-value products. Oil can be used in a variety of ways because it contains hydrocarbons of varying molecular masses , forms and lengths such as paraffins , aromatics , naphthenes (or cycloalkanes ), alkenes , dienes , and alkynes . While

The systematic review did mention that several of the associations were not due to factors directly related to the petroleum industry, rather were related to lifestyle factors such as smoking . Evidence for adverse health effects for nearby residents

7068-408: The vacuum distillation unit may also produce fractions that can be refined into end products such as spindle oil used in the textile industry, light machine oil, motor oil, and various waxes. The crude oil distillation unit (CDU) is the first processing unit in virtually all petroleum refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which

7192-399: The viscosity of the oil). All of the many other refining processes discussed below were developed during the war or within a few years after the war. They became commercially available within 5 to 10 years after the war ended and the worldwide petroleum industry experienced very rapid growth. The driving force for that growth in technology and in the number and size of refineries worldwide was

7316-628: The 12th century. In the Northern Song dynasty (960–1127), a workshop called the "Fierce Oil Workshop", was established in the city of Kaifeng to produce refined oil for the Song military as a weapon. The troops would then fill iron cans with refined oil and throw them toward the enemy troops, causing a fire – effectively the world's first " fire bomb ". The workshop was one of the world's earliest oil refining factories where thousands of people worked to produce Chinese oil-powered weaponry. Prior to

7440-860: The 1800s, primarily producing kerosene for oil lamps. In the early twentieth century, the introduction of the internal combustion engine and its use in automobiles created a market for gasoline that was the impetus for fairly rapid growth of the petroleum industry. The early finds of petroleum like those in Ontario and Pennsylvania were soon outstripped by large oil "booms" in Oklahoma , Texas and California . Samuel Kier established America's first oil refinery in Pittsburgh on Seventh Avenue near Grant Street, in 1853. Polish pharmacist and inventor Ignacy Łukasiewicz established an oil refinery in Jasło , then part of

7564-433: The 1920s through 1940s, running either spark-ignition and low-compression engines, akryod engines, or diesel engines. Thus many farm tractors of the era could burn gasoline, alcohol , kerosene , and any light grade of fuel oil such as heating oil , or tractor vaporising oil , according to whichever was most affordable in a region at any given time. On US farms during this era, the name "distillate" often referred to any of

7688-541: The 1920s through 1950s, are now almost exclusively diesel-powered. Due to its ignition characteristics, diesel fuel is thus widely used in these vehicles. Since diesel fuel is not well-suited for otto engines, passenger cars, which often use otto or otto-derived engines, typically run on petrol instead of diesel fuel. However, especially in Europe and India, many passenger cars have, due to better engine efficiency, diesel engines, and thus run on regular diesel fuel. Diesel displaced coal and fuel oil for steam-powered vehicles in

7812-423: The 1930s outweighed these advantages, and aircraft diesel engines quickly fell out of use. With improvements in power-to-mass ratios of diesel engines, several on-road diesel engines have been converted to and certified for aircraft use since the early 21st century. These engines typically run on Jet A-1 aircraft fuel (but can also run on diesel fuel). Jet A-1 has ignition characteristics similar to diesel fuel, and

Modern petroleum refining involves a complicated system of interrelated chemical reactions that produce a wide variety of petroleum-based products. Many of these reactions require precise temperature and pressure parameters.   The equipment and monitoring required to ensure

8184-534: The Diesel engine being kerosene ( paraffin ). Diesel experimented with types of lamp oil from various sources, as well as types of petrol and ligroin , which all worked well as Diesel engine fuels. Later, Diesel tested coal tar creosote , paraffin oil, crude oil, gasoline and fuel oil , which eventually worked as well. In Scotland and France, shale oil was used as fuel for the first 1898 production Diesel engines because other fuels were too expensive. In 1900,

8308-594: The French Otto society built a Diesel engine for the use with crude oil, which was exhibited at the 1900 Paris Exposition and the 1911 World's Fair in Paris. The engine actually ran on peanut oil instead of crude oil, and no modifications were necessary for peanut oil operation. During his first Diesel engine tests, Diesel also used illuminating gas as fuel, and managed to build functional designs, both with and without pilot injection. According to Diesel, neither

8432-704: The Porvoo refinery, was brought on stream in 2007, together with a new conventional diesel production line. In the same year, the entire bus fleet of Helsinki Region Transport switched fully to diesel produced using NEXBTL technology. Experiments by Neste, VTT Technical Research Centre of Finland and Proventia showed that local emissions decreased significantly after the switch, with overall particle emissions decreasing by 30% and nitrogen oxide emissions by 10%, with excellent winter performance and no problems with catalytic converters . A second renewable diesel plant at Porvoo became operational in 2009. In 2007, Neste started

8556-584: The U.S. from 1976 until 2014 when the small Dakota Prairie Refinery in North Dakota began operation. More than half the refineries that existed in 1981 are now closed due to low utilization rates and accelerating mergers. As a result of these closures total US refinery capacity fell between 1981 and 1995, though the operating capacity stayed fairly constant in that time period at around 15,000,000 barrels per day (2,400,000 m /d). Increases in facility size and improvements in efficiencies have offset much of

8680-483: The UK, diesel is normally stored in a black container to differentiate it from unleaded or leaded petrol, which are stored in green and red containers, respectively. Ethylene-vinyl acetate (EVA) is added to diesel as a "cold flow improver". 50-500 ppm of EVA inhibits crystallization of waxes, which can block fuel filters. Antifoaming agents ( silicones ), antioxidants ( hindered phenols ), and "metal deactivating agents" (salicylaldimines) are other additives. Their use

8804-452: The US. Methanol can also be replaced with ethanol for the transesterification process, which results in the production of ethyl esters. The transesterification processes use catalysts, such as sodium or potassium hydroxide, to convert vegetable oil and methanol into biodiesel and the undesirable byproducts glycerine and water, which will need to be removed from the fuel along with methanol traces. Biodiesel can be used pure (B100) in engines where

8928-453: The United Kingdom, mainland Europe, and North America is of a ULSD type. Before diesel fuel had been standardized, the majority of diesel engines typically ran on cheap fuel oils . These fuel oils are still used in watercraft diesel engines. Despite being specifically designed for diesel engines, diesel fuel can also be used as fuel for several non-diesel engines, for example the Akroyd engine ,

9052-413: The aforementioned light fuel oils. Spark ignition engines did not start as well on distillate, so typically a small auxiliary gasoline tank was used for cold starting, and the fuel valves were adjusted several minutes later, after warm-up, to transition to distillate. Engine accessories such as vaporizers and radiator shrouds were also used, both with the aim of capturing heat, because when such an engine

9176-680: The blend, so that B20 fuel is taxed 20% less than pure petrodiesel. Other states, such as North Carolina, tax biodiesel (in any blended configuration) the same as petrodiesel, although they have introduced new incentives to producers and users of all biofuels. Diesel fuel is mostly used in high-speed diesel engines, especially motor-vehicle (e.g. car, lorry) diesel engines, but not all diesel engines run on diesel fuel. For example, large two-stroke watercraft engines typically use heavy fuel oils instead of diesel fuel, and certain types of diesel engines, such as MAN M-System engines, are designed to run on petrol with knock resistances of up to 86 RON. On

9300-585: The commercial-scale production of bio-based plastic from renewable materials. In March 2020, Neste invested in German Sunfire, a company developing high-temperature electrolysis technology. In September, Neste sold its 49.99% stake in Nynas to Bitumina Industries, and began closure-related negotiations for the Naantali refinery. The refinery was planned to close by the end of March 2021. As part of

9424-555: The company was bought by the Deutsche Erdöl-AG and Edeleanu, being of Jewish origin, moved back to Romania. After the war, the trademark was used by the successor company EDELEANU Gesellschaft mbH Alzenau (RWE) for many petroleum products, while the company was lately integrated as EDL in the Pörner Group . The Ploiești refineries, after being taken over by Nazi Germany , were bombed in the 1943 Operation Tidal Wave by

9548-644: The company's name was changed from Neste Oil back to Neste to emphasize the company's focus on the renewable energy business. In 2017, Neste acquired Jacobs Engineering's 40% stake in Neste Jacobs and gained full control of the company. After the takeover, Neste Jacobs was renamed Neste Engineering Solutions Oy. When CEO Lievonen retired in November 2018, he was followed by the Belgian - German Peter Vanacker. In June, Neste and LyondellBasell announced

9672-555: The construction of new refineries may have also contributed to rising fuel prices in the United States. Additionally, many refineries (more than 100 since the 1980s) have closed due to obsolescence and/or merger activity within the industry itself. Environmental and safety concerns mean that oil refineries are sometimes located some distance away from major urban areas. Nevertheless, there are many instances where refinery operations are close to populated areas and pose health risks. In California's Contra Costa County and Solano County ,

9796-987: The cooperation, Neste produces hydrocarbons from renewable raw materials as a feedstock to manufacture phenol by Borealis. Phenol is used by Covestro to produce polycarbonate plastics, which would primarily be used for car headlights and window coatings. In December 2021, CEO Vanacker resigned to become the CEO of LyondellBasell . Matti Lehmus became CEO in May 2022. Neste's operations are divided into marketing and services, oil products, renewable aviation, renewable polymers and chemicals, and renewable road transportation units, as well as managing an operating platform. In 2022 Neste operated conventional oil refineries at Porvoo in Finland and renewable diesel refineries in Porvoo, Singapore and Rotterdam, Netherlands. In 2015, two renewable diesel production lines in Porvoo produced 0.525 million metric tonnes of renewable diesel, which

9920-667: The crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. The largest share of oil products is used as "energy carriers", i.e. various grades of fuel oil and gasoline . These fuels include or can be blended to give gasoline, jet fuel , diesel fuel , heating oil , and heavier fuel oils. Heavier (less volatile ) fractions can also be used to produce asphalt , tar , paraffin wax , lubricating and other heavy oils. Refineries also produce other chemicals , some of which are used in chemical processes to produce plastics and other useful materials. Since petroleum often contains

10044-487: The desalter, the crude oil is further heated by exchanging heat with some of the hot, distilled fractions and other streams. It is then heated in a fuel-fired furnace (fired heater) to a temperature of about 398 °C and routed into the bottom of the distillation unit. The cooling and condensing of the distillation tower overhead is provided partially by exchanging heat with the incoming crude oil and partially by either an air-cooled or water-cooled condenser. Additional heat

10168-443: The equipment needed to comply with the requirements of the pertinent environmental protection regulatory agencies. In the United States, there is strong pressure to prevent the development of new refineries, and no major refinery has been built in the country since Marathon's Garyville, Louisiana facility in 1976. However, many existing refineries have been expanded during that time. Environmental restrictions and pressure to prevent

10292-422: The five largest shareholders of Neste were: Neste has a target to make its production carbon neutral by 2035. Neste has been criticized for using palm oil and palm fatty acid distillate, a by‐product of physical refining of crude palm oil products, as a part of its feedstock for renewable products. Critics include of WWF , Greenpeace , Biofuelwatch and Milieudefensie , among others. Neste consumes 1–2% of

10416-412: The growing demand for automotive gasoline and aircraft fuel. In the United States, for various complex economic and political reasons, the construction of new refineries came to a virtual stop in about the 1980s. However, many of the existing refineries in the United States have revamped many of their units and/or constructed add-on units in order to: increase their crude oil processing capacity, increase

10540-514: The highly automated and technically advanced nature of modern petroleum refineries, nearly all processes are contained within engineering controls and represent a substantially decreased risk of exposure to workers compared to earlier times. However, certain situations or work tasks may subvert these safety mechanisms, and expose workers to a number of chemical (see table above) or physical (described below) hazards. Examples of these scenarios include: A 2021 systematic review associated working in

10664-542: The hundreds of different hydrocarbon molecules in crude oil are separated in a refinery into components that can be used as fuels , lubricants , and feedstocks in petrochemical processes that manufacture such products as plastics , detergents , solvents , elastomers , and fibers such as nylon and polyesters . Petroleum fossil fuels are burned in internal combustion engines to provide power for ships , automobiles , aircraft engines , lawn mowers , dirt bikes , and other machines. Different boiling points allow

10788-480: The inlet crude oil feedstock and the final end products. The diagram depicts only one of the literally hundreds of different oil refinery configurations. The diagram also does not include any of the usual refinery facilities providing utilities such as steam, cooling water, and electric power as well as storage tanks for crude oil feedstock and for intermediate products and end products. There are many process configurations other than that depicted above. For example,

10912-621: The late Northern Wei dynasty , the Chinese geographer, writer and politician Li Daoyuan introduced the process of refining oil into various lubricants in his famous work Commentary on the Water Classic . Crude oil was often distilled by Persian chemists , with clear descriptions given in handbooks such as those of Muhammad ibn Zakarīya Rāzi ( c.  865–925 ). The streets of Baghdad were paved with tar , derived from petroleum that became accessible from natural fields in

11036-425: The latter half of the 20th century, and is now used almost exclusively for the combustion engines of self-powered rail vehicles (locomotives and railcars). In general, diesel engines are not well-suited for planes and helicopters. This is because of the diesel engine's comparatively low power-to-mass ratio , meaning that diesel engines are typically rather heavy, which is a disadvantage in aircraft. Therefore, there

11160-411: The less profitable refineries. Raw or unprocessed crude oil is not generally useful in industrial applications, although "light, sweet" (low viscosity, low sulfur ) crude oil has been used directly as a burner fuel to produce steam for the propulsion of seagoing vessels. The lighter elements, however, form explosive vapors in the fuel tanks and are therefore hazardous, especially in warships . Instead,

11284-415: The lost physical capacity of the industry. In 1982 (the earliest data provided), the United States operated 301 refineries with a combined capacity of 17.9 million barrels (2,850,000 m ) of crude oil each calendar day. In 2010, there were 149 operable U.S. refineries with a combined capacity of 17.6 million barrels (2,800,000 m ) per calendar day. By 2014 the number of refinery had reduced to 140 but

11408-576: The majority owner of Finnoil. Kesoil also became a wholly owned subsidiary . In 1992, Union service stations became Neste service stations. The following year the same happened to Finnoil service stations. In 1994, Gasum was established with Gazprom as a minor (25%) shareholder. In 1994, Neste's polyolefin production was separated into Borealis , a joint venture with the Norwegian Statoil . In 1998, Neste's 50% stake in Borealis

11532-489: The manufacturer approves such use, but it is more often used as a mix with diesel, BXX where XX is the biodiesel content in percent. FAME used as fuel is specified in DIN EN 14214 and ASTM D6751 standards. In the US, diesel is recommended to be stored in a yellow container to differentiate it from kerosene , which is typically kept in blue containers, and gasoline (petrol), which is typically kept in red containers. In

11656-487: The merger the chemical operations of Neste were transferred to the newly established company Neste Chemicals , which was sold to the investment firm Industri Kapital for $ 535 million. In 1998, Kesoil service stations also became Neste stations. An engineering joint venture, Neste Jacobs Oy, was established with the American Jacobs Engineering in 2004. In May 2004, Fortum Oil and Gas Corporation

11780-436: The molecules in crude oil include different atoms such as sulfur and nitrogen, the hydrocarbons are the most common form of molecules, which are molecules of varying lengths and complexity made of hydrogen and carbon atoms , and a small number of oxygen atoms. The differences in the structure of these molecules account for their varying physical and chemical properties , and it is this variety that makes crude oil useful in

11904-443: The new EN 590 standard, which has been used in the European Union ever since. In sea-going watercraft, where diesel propulsion had gained prevalence by the late 1970s due to increasing fuel costs caused by the 1970s energy crisis , cheap heavy fuel oils are still used instead of conventional motor-vehicle diesel fuel. These heavy fuel oils (often called Bunker C ) can be used in diesel-powered and steam-powered vessels. Diesel fuel

12028-487: The nineteenth century, petroleum was known and utilized in various fashions in Babylon , Egypt , China , Philippines , Rome and Azerbaijan . However, the modern history of the petroleum industry is said to have begun in 1846 when Abraham Gessner of Nova Scotia , Canada devised a process to produce kerosene from coal. Shortly thereafter, in 1854, Ignacy Łukasiewicz began producing kerosene from hand-dug oil wells near

12152-406: The operating principle of his rational heat motor would work with any kind of fuel in any state of matter. The first diesel engine prototype and the first functional Diesel engine were only designed for liquid fuels. At first, Diesel tested crude oil from Pechelbronn , but soon replaced it with petrol and kerosene , because crude oil proved to be too viscous, with the main testing fuel for

12276-466: The operations of Neste, the oil crisis of 1973 had little effect in Finland. In 1976, Finland's first skyscraper , Neste's 83.6-meter tall headquarters, was built in Keilaniemi , Espoo. In 1980, Jaakko Ihamuotila became the CEO. Neste started its service station operations in 1983. Neste held a legal import monopoly until the market liberalization in the 1990s. In 1991, Neste became

12400-598: The other hand, gas turbine and some other types of internal combustion engines, and external combustion engines , can also be designed to take diesel fuel. The viscosity requirement of diesel fuel is usually specified at 40 °C. A disadvantage of diesel fuel in cold climates is that its viscosity increases as the temperature decreases, changing it into a gel (see Compression Ignition – Gelling ) that cannot flow in fuel systems. Special low-temperature diesel contains additives to keep it liquid at lower temperatures. Trucks and buses , which were often otto-powered in

12524-414: The past, diesel fuel contained higher quantities of sulfur . European emission standards and preferential taxation have forced oil refineries to dramatically reduce the level of sulfur in diesel fuels. In the European Union, the sulfur content has dramatically reduced during the last 20 years. Automotive diesel fuel is covered in the European Union by standard EN 590 . In the 1990s specifications allowed

12648-421: The petrol fuel tax. Diesel fuel is similar to heating oil , which is used in central heating . In Europe, the United States, and Canada, taxes on diesel fuel are higher than on heating oil due to the fuel tax , and in those areas, heating oil is marked with fuel dyes and trace chemicals to prevent and detect tax fraud . "Untaxed" diesel (sometimes called "off-road diesel" or "red diesel" due to its red dye)

12772-464: The product stream via amine gas treating . Using the Claus process , hydrogen sulfide is afterward transformed to elementary sulfur to be sold to the chemical industry. The rather large heat energy freed by this process is directly used in the other parts of the refinery. Often an electrical power plant is combined into the whole refinery process to take up the excess heat. According to the composition of

12896-455: The proper progression of these processes is complex, and has evolved through the advancement of the scientific field of petroleum engineering . The wide array of high pressure and/or high temperature reactions, along with the necessary chemical additives or extracted contaminants, produces an astonishing number of potential health hazards to the oil refinery worker.  Through the advancement of technical chemical and petroleum engineering,

13020-626: The region. In the 9th century, oil fields were exploited in the area around modern Baku , Azerbaijan. These fields were described by the Arab geographer Abu al-Hasan 'Alī al-Mas'ūdī in the 10th century, and by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads. Arab and Persian chemists also distilled crude oil in order to produce flammable products for military purposes. Through Islamic Spain , distillation became available in Western Europe by

13144-503: The saturated hydrocarbons as desired. Another refinery stream that contributes to diesel fuel is hydrocracking . Finally, kerosene is added to modify its viscosity. Synthetic diesel can be produced from many carbonaceous precursors but natural gas is most important. Raw materials are converted to synthesis gas which by the Fischer–Tropsch process is converted to a synthetic diesel. Synthetic diesel produced in this way generally

13268-461: The smaller classes may also offer gasoline-fuelled engines. The dieselization of tractors and heavy equipment began in Germany before World War II but was unusual in the United States until after that war. During the 1950s and 1960s, it progressed in the US as well. Diesel fuel is commonly used in oil and gas extracting equipment, although some locales use electric or natural gas powered equipment. Tractors and heavy equipment were often multifuel in

13392-609: The time, reports of the health impacts of working in an oil refinery can be found as early as the 1800s. For instance, an explosion in a Chicago refinery killed 20 workers in 1890. Since then, numerous fires, explosions, and other significant events have from time to time drawn the public's attention to the health of oil refinery workers. Such events continue in the 21st century, with explosions reported in refineries in Wisconsin and Germany in 2018. However, there are many less visible hazards that endanger oil refinery workers. Given

13516-458: The total capacity increased to 18.02 million barrels (2,865,000 m ) per calendar day. Indeed, in order to reduce operating costs and depreciation, refining is operated in fewer sites but of bigger capacity. In 2009 through 2010, as revenue streams in the oil business dried up and profitability of oil refineries fell due to lower demand for product and high reserves of supply preceding the economic recession , oil companies began to close or sell

13640-621: The town of Krosno , Poland . Romania was registered as the first country in world oil production statistics, according to the Academy Of World Records . In North America, the first oil well was drilled in 1858 by James Miller Williams in Oil Springs, Ontario , Canada. In the United States, the petroleum industry began in 1859 when Edwin Drake found oil near Titusville , Pennsylvania . The industry grew slowly in

13764-509: The use of nuclear fuel . Diesel fuel is often used as the main ingredient in oil-base mud drilling fluid. The advantage of using diesel is its low cost and its ability to drill a wide variety of difficult strata, including shale, salt and gypsum formations. Diesel-oil mud is typically mixed with up to 40% brine water. Due to health, safety and environmental concerns, Diesel-oil mud is often replaced with vegetable, mineral, or synthetic food-grade oil-base drilling fluids, although diesel-oil mud

13888-616: The user can be fined (e.g. US$ 10,000 in the US). In the United Kingdom, Belgium and the Netherlands, it is known as red diesel (or gas oil), and is also used in agricultural vehicles, home heating tanks, refrigeration units on vans/trucks which contain perishable items such as food and medicine and for marine craft. Diesel fuel, or marked gas oil is dyed green in the Republic of Ireland and Norway. The term "diesel-engined road vehicle" (DERV)

14012-420: The vast majority of these processes are automated and enclosed, thus greatly reducing the potential health impact to workers.   However, depending on the specific process in which a worker is engaged, as well as the particular method employed by the refinery in which he/she works, significant health hazards remain. Although occupational injuries in the United States were not routinely tracked and reported at

14136-601: The world's largest oil refinery has been the Jamnagar Refinery owned by Reliance Industries , located in Gujarat , India, with a processing capacity of 1.24 million barrels (197,000 m ) per day. Oil refineries are an essential part of the petroleum industry's downstream sector. The Chinese were among the first civilizations to refine oil. As early as the first century, the Chinese were refining crude oil for use as an energy source. Between 512 and 518, in

14260-497: The world's total palm oil production. In 2016, less than 20% of renewable raw materials used by Neste was crude palm oil. Crude palm oil used by the company has been traceable to the oil palm plantation level since 2007, and has been 100% certified since 2013. However, certification does not apply to palm fatty acid distillate. Since 2016, Neste has published information about all its crude palm oil suppliers on its website. Oil refinery An oil refinery or petroleum refinery

14384-489: Was a coal-dust–producing industry existent, nor was fine, high-quality coal-dust commercially available in the late 1890s. This is the reason why the Diesel engine was never designed or planned as a coal-dust engine. Only in December 1899, did Diesel test a coal-dust prototype, which used external mixture formation and liquid fuel pilot injection. This engine proved to be functional, but suffered from piston ring failure after

14508-456: Was also weak, with the evidence primarily centering around neighborhoods in developed countries . Diesel fuel The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil , but alternatives that are not derived from petroleum, such as biodiesel , biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel

14632-463: Was approximately one fifth of the diesel consumption of Finland. Neste's production facility in Singapore is the largest renewable diesel refinery in the world, with an annual capacity of 1.1 million metric tonnes. A planned new production line is expected to increase its capacity by one million tonnes in 2022. Neste's refinery feedstock includes of crude oil and renewable raw materials, such as used cooking fat , waste animal and fish fat from

14756-503: Was considered waste and was often dumped directly into the nearest river. The invention of the automobile shifted the demand to gasoline and diesel, which remain the primary refined products today. Today, national and state legislation require refineries to meet stringent air and water cleanliness standards. In fact, oil companies in the U.S. perceive obtaining a permit to build a modern refinery to be so difficult and costly that no new refineries were built (though many have been expanded) in

14880-589: Was established in Espoo. In 1955, Uolevi Raade became the company's CEO . In 1957, the first oil refinery in Finland was built at Naantali using US technology. The Porvoo refinery was built in 1965 in Sköldvik (Kilpilahti). Originally, much of the oil refined was of Soviet origin, though North Sea oil was used after the collapse of the USSR. In 1971, Neste acquired half of Kesko -owned Kesoil. Because of

15004-494: Was run on distillate, it ran better when both it and the air it inhaled were warmer rather than at ambient temperature. Dieselization with dedicated diesel engines (high-compression with mechanical fuel injection and compression ignition) replaced such systems and made more efficient use of the diesel fuel being burned. Poor quality diesel fuel has been used as an extraction agent for liquid–liquid extraction of palladium from nitric acid mixtures. Such use has been proposed as

15128-555: Was sold to OMV and IPIC . In 1994, Neste began as the main sponsor of a competition previously known as the Finnish Rally and renamed Neste Rally Finland . In October 2020, Neste ended its 26-year title sponsorship. In November 1995, the company was listed on the main list of the Helsinki Stock Exchange . In 1998, Neste merged with the power company Imatran Voima Oy to create Fortum Oyj . After

15252-757: Was split into two: the company's oil business was renamed Fortum Oil Corporation and other operations renamed Fortum Heat and Gas Corporation. Fortum Oil Corporation was a subsidiary of Fortum Corporation. In the spring of 2005, Fortum Oil Corporation was demerged from Fortum, becoming the Neste Oil Corporation. Neste Oil Corporation was listed on the Helsinki Stock Exchange in June 2005. Risto Rinne started as Ihamuotila's successor and CEO. A renewable diesel plant, using second generation biofuels and NEXBTL technology and located at

15376-846: Was the Abadan Refinery in Iran . This refinery suffered extensive damage during the Iran–Iraq War . Since 25 December 2008, the world's largest refinery complex is the Jamnagar Refinery Complex, consisting of two refineries side by side operated by Reliance Industries Limited in Jamnagar, India with a combined production capacity of 1,240,000 barrels per day (197,000 m /d). PDVSA 's Paraguaná Refinery Complex in Paraguaná Peninsula , Venezuela , with
