The Kirishi-2 Oil Refinery is Russia's first residual oil high conversion refinery . It was opened in Kirishi , Russia in 2017. It is located on the site of the KINEF refinery.
93-551: The Kirishi-2 Oil Refinery produces a high yield of light oil (73.12%) and high-quality motor fuels . Its products include AI-95 motor gasoline , gas petrochemicals, diesel , kerosene , LPG , isobutene , N-butane , petroleum coke , propane and sulphur . The Kirishi-2 Oil Refinery has an annual output of 10 million tons. As of 2024 the refinery produced approximately 11 percent of Russia's total output gasoline, 6.4 percent of its diesel fuel, 5.6 percent of fuel oil, and 7.4 percent of its aviation fuel . The Kirishi-2 refinery
186-414: A backup fuel for peaking power plants in case the supply of natural gas is interrupted or as the main fuel for small electrical generators . In Europe, the use of diesel is generally restricted to cars (about 40%), SUVs (about 90%), and trucks and buses (over 99%). The market for home heating using fuel oil has decreased due to the widespread penetration of natural gas as well as heat pumps . However, it
279-404: A bunker fuel as the fuel that powers the engine of a ship or aircraft. Bunker A is No. 4 fuel oil, bunker B is No. 5, and bunker C is No. 6. Since No. 6 is the most common, "bunker fuel" is often used as a synonym for No. 6. No. 5 fuel oil is also called Navy Special Fuel Oil ( NSFO ) or just navy special ; No. 5 or 6 are also commonly called heavy fuel oil ( HFO ) or furnace fuel oil ( FFO );
372-794: A convenient seaport does not exist, inland transport may be achieved with the use of barges . Lighter fuel oils can also be transported through pipelines . The major physical supply chains of Europe are along the Rhine River . Emissions from bunker fuel burning in ships contribute to climate change and to air pollution levels in many port cities, especially where the emissions from industry and road traffic have been controlled. The switch of auxiliary engines from heavy fuel oil to diesel oil at berth can result in large emission reductions, especially for SO 2 and PM . CO 2 emissions from bunker fuels sold are not added to national GHG emissions. For small countries with large international ports, there
465-481: A density 0.5539 times that of air (0.678 kg per standard cubic meter). In the early 1800s, natural gas became known as "natural" to distinguish it from the dominant gas fuel at the time, coal gas . Unlike coal gas, which is manufactured by heating coal, natural gas can be extracted from the ground in its native gaseous form. When the use of natural gas overtook the use of coal gas in English speaking countries in
558-461: A high percentage of overall deaths from transport sector air pollution. In Taiwan, shipping accounts for 70% of all transport-attributable air pollution deaths in 2015, followed by Morocco at 51%, Malaysia and Japan both at 41%, Vietnam at 39%, and the UK at 38%. As well as commercial shipping, cruise ships also emit large amounts of air pollution, damaging people's health. Up to 2019, it was reported that
651-484: A major source of natural gas in the United States and Canada. Because of increased shale gas production the United States was in 2014 the number one natural gas producer in the world. The production of shale gas in the United States has been described as a "shale gas revolution" and as "one of the landmark events in the 21st century." Following the increased production in the United States, shale gas exploration
744-404: A river or ocean, residual oil tends to break up into patches or tarballs – mixtures of oil and particulate matter such as silt and floating organic matter – rather than form a single slick. An average of about 5-10% of the material will evaporate within hours of the release, primarily the lighter hydrocarbon fractions. The remainder will then often sink to the bottom of the water column. Because of
837-411: A simpler one such as gas or No. 2 oil. The high sulfur content of No. 6 oil—up to 3% by weight in some extreme cases—had a corrosive effect on many heating systems (which were usually designed without adequate corrosion protection in mind), shortening their lifespans and increasing the polluting effects. This was particularly the case in furnaces that were regularly shut down and allowed to go cold, because
930-542: A synthetic crude that can be further refined into finished products, while MTG can produce synthetic gasoline from natural gas. STG+ can produce drop-in gasoline, diesel, jet fuel and aromatic chemicals directly from natural gas via a single-loop process. In 2011, Royal Dutch Shell's 140,000 barrels (22,000 m ) per day F–T plant went into operation in Qatar . Natural gas can be "associated" (found in oil fields ), or "non-associated" (isolated in natural gas fields ), and
1023-543: A tarry semisolid. The flash point of most blends of No. 6 oil is, incidentally, about 65 °C (149 °F). Attempting to pump high-viscosity oil at low temperatures was a frequent cause of damage to fuel lines, furnaces, and related equipment which were often designed for lighter fuels. For comparison, BS 2869 Class G heavy fuel oil behaves in similar fashion, requiring storage at 40 °C (104 °F), pumping at around 50 °C (122 °F) and finalizing for burning at around 90–120 °C (194–248 °F). Most of
SECTION 10
#17327868469351116-442: Is ISO 8217: 2017. The standard divides fuels into residual and distillate fuels. The most common residual fuels in the shipping industry are RMG and RMK. The differences between the two are mainly the density and viscosity, with RMG generally being delivered at 380 centistokes or less, and RMK at 700 centistokes or less. Ships with more advanced engines can process heavier, more viscous, and thus cheaper, fuel. Governing bodies around
1209-427: Is a distillate home heating oil . Trucks and some cars use similar diesel no. 2 with a cetane number limit describing the ignition quality of the fuel. Both are typically obtained from the light gas oil cut. The name gasoil refers to the original use of this fraction in the late 19th and early 20th centuries—the gas oil cut was used as an enriching agent for carbureted water gas manufacture . Number 3 fuel oil
1302-493: Is a flammable gaseous fuel made by the destructive distillation of coal . It contains a variety of calorific gases including hydrogen , carbon monoxide , methane , and other volatile hydrocarbons , together with small quantities of non-calorific gases such as carbon dioxide and nitrogen , and was used in a similar way to natural gas. This is a historical technology and is not usually economically competitive with other sources of fuel gas today. Most town "gashouses" located in
1395-652: Is a high-viscosity residual oil requiring preheating to 104–127 °C (219–261 °F). Residual means the material remaining after the more valuable cuts of crude oil have boiled off. The residue may contain various undesirable impurities, including 2% water and 0.5% mineral oil . This fuel may be known as residual fuel oil (RFO), by the Navy specification of Bunker C , or by the Pacific Specification of PS-400. The British Standard BS 2869, Fuel Oils for Agricultural, Domestic and Industrial Engines , specifies
1488-421: Is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) in addition to various smaller amounts of other higher alkanes . Traces of carbon dioxide , nitrogen , hydrogen sulfide , and helium are also usually present. Methane is colorless and odorless, and the second largest greenhouse gas contributor to global climate change after carbon dioxide. Because natural gas
1581-403: Is a residual-type industrial heating oil requiring preheating to 77–104 °C (171–219 °F) for proper atomization at the burners. It may be obtained from the heavy gas oil cut, or it may be a blend of residual oil with enough number 2 oil to adjust viscosity until it can be pumped without preheating. This fuel is sometimes known by the Navy specification of Bunker B . Number 6 fuel oil
1674-458: Is a schematic block flow diagram of a typical natural gas processing plant. It shows the various unit processes used to convert raw natural gas into sales gas pipelined to the end user markets. The block flow diagram also shows how processing of the raw natural gas yields byproduct sulfur, byproduct ethane, and natural gas liquids (NGL) propane, butanes and natural gasoline (denoted as pentanes +). As of mid-2020, natural gas production in
1767-399: Is also found in coal beds (as coalbed methane ). It sometimes contains a significant amount of ethane , propane , butane , and pentane —heavier hydrocarbons removed for commercial use prior to the methane being sold as a consumer fuel or chemical plant feedstock. Non-hydrocarbons such as carbon dioxide , nitrogen , helium (rarely), and hydrogen sulfide must also be removed before
1860-413: Is also possible to purify oil with a density of 1010 kg/m3. The first British standard for fuel oil came in 1982. The latest standard is ISO 8217 issued in 2017. The ISO standard describe four qualities of distillate fuels and 10 qualities of residual fuels. Over the years the standards have become stricter on environmentally important parameters such as sulfur content. The latest standard also banned
1953-569: Is an important difference between the emissions in territorial waters and the total emissions of the fuel sold. At the 1997 Third Conference of the Parties in Kyoto, Japan, countries agreed to exempt bunker fuels, and multilateral military operations, from national emissions totals after insistence from the U.S. climate change delegation for such exemptions. Natural gas Natural gas (also called fossil gas, methane gas , or simply gas )
SECTION 20
#17327868469352046-628: Is beginning in countries such as Poland, China, and South Africa. Chinese geologists have identified the Sichuan Basin as a promising target for shale gas drilling, because of the similarity of shales to those that have proven productive in the United States. Production from the Wei-201 well is between 10,000 and 20,000 m per day. In late 2020, China National Petroleum Corporation claimed daily production of 20 million cubic meters of gas from its Changning-Weiyuan demonstration zone. Town gas
2139-728: Is burned in a furnace or boiler to generate heat ( heating oils ), or used in an engine to generate power (as motor fuels ). However, it does not usually include other liquid oils, such as those with a flash point of approximately 42 °C (108 °F), or oils burned in cotton- or wool-wick burners. In a stricter sense, fuel oil refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha . Fuel oil consists of long-chain hydrocarbons , particularly alkanes , cycloalkanes , and aromatics . Small molecules, such as those in propane , naphtha, gasoline, and kerosene , have relatively low boiling points , and are removed at
2232-560: Is either blended with lighter petroleum fractions or burned directly in specialized boilers and furnaces. It is also used as a petrochemical feedstock. In the Russian practice, though, "mazut" is an umbrella term roughly synonymous with the fuel oil in general, that covers most of the types mentioned above, except US grades 1 and 2/3, for which separate terms exist ( kerosene and diesel fuel /solar oil respectively — Russian practice doesn't differentiate between diesel fuel and heating oil). This
2325-537: Is estimated to have 51,000 cubic kilometers (12,000 cu mi) of natural gas and 50 billion barrels (7.9 billion cubic meters) of natural gas condensates . Because natural gas is not a pure product, as the reservoir pressure drops when non-associated gas is extracted from a field under supercritical (pressure/temperature) conditions, the higher molecular weight components may partially condense upon isothermic depressurizing—an effect called retrograde condensation . The liquid thus formed may get trapped as
2418-460: Is further separated in two grades, "naval mazut" being analogous to US grades 4 and 5, and "furnace mazut", a heaviest residual fraction of the crude, almost exactly corresponding to US Number 6 fuel oil and further graded by viscosity and sulfur content. In the maritime field another type of classification is used for fuel oils: Marine diesel oil contains some heavy fuel oil, unlike regular diesels. CCAI and CII are two indexes which describe
2511-694: Is heated and compressed deep underground. Methanogenic organisms produce methane from a variety of sources, principally carbon dioxide. During petroleum production, natural gas is sometimes flared rather than being collected and used. Before natural gas can be burned as a fuel or used in manufacturing processes, it almost always has to be processed to remove impurities such as water. The byproducts of this processing include ethane , propane , butanes , pentanes , and higher molecular weight hydrocarbons. Hydrogen sulfide (which may be converted into pure sulfur ), carbon dioxide , water vapor , and sometimes helium and nitrogen must also be removed. Natural gas
2604-522: Is its high initial viscosity, particularly in the case of No. 6 oil, which requires a correctly engineered system for storage, pumping, and burning. Though it is still usually lighter than water (with a specific gravity usually ranging from 0.95 to 1.03) it is much heavier and more viscous than No. 2 oil, kerosene, or gasoline. No. 6 oil must, in fact, be stored at around 38 °C (100 °F) heated to 65–120 °C (149–248 °F) before it can be easily pumped, and in cooler temperatures it can congeal into
2697-403: Is natural gas produced from shale . Because shale's matrix permeability is too low to allow gas to flow in economical quantities, shale gas wells depend on fractures to allow the gas to flow. Early shale gas wells depended on natural fractures through which gas flowed; almost all shale gas wells today require fractures artificially created by hydraulic fracturing . Since 2000, shale gas has become
2790-408: Is odorless, odorizers such as mercaptan (which smells like rotten eggs ) are commonly added to it for safety so that leaks can be readily detected. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that
2883-406: Is often stored underground [references about geological storage needed]inside depleted gas reservoirs from previous gas wells, salt domes , or in tanks as liquefied natural gas. The gas is injected in a time of low demand and extracted when demand picks up. Storage nearby end users helps to meet volatile demands, but such storage may not always be practicable. With 15 countries accounting for 84% of

2976-651: Is owned by Surgutneftegaz 's Kirishinefteorgsintez subsidiary. The refinery project was managed by Giorgi Ramzaitsev , the chairman of the Board of Directors of ChekSU , a major manganese ore and ferroalloy mining and processing company in Russia, and Andrei Yermolaev , a former member of the Leningrad Regional Legislative Assembly . On 12 March 2024 the refinery was attacked by Ukrainian drones. Reuters reported that at least half of
3069-452: Is preparing to export natural gas. Floating liquefied natural gas (FLNG) is an innovative technology designed to enable the development of offshore gas resources that would otherwise remain untapped due to environmental or economic factors which currently make them impractical to develop via a land-based LNG operation. FLNG technology also provides a number of environmental and economic advantages: Many gas and oil companies are considering
3162-548: Is primarily dependent on proximity to markets (pipelines), and regulatory restrictions. Natural gas can be indirectly exported through the absorption in other physical output. The expansion of shale gas production in the US has caused prices to drop relative to other countries. This has caused a boom in energy intensive manufacturing sector exports, whereby the average dollar unit of US manufacturing exports has almost tripled its energy content between 1996 and 2012. A "master gas system"
3255-429: Is primarily used in the northern hemisphere. North America and Europe are major consumers. Often well head gases require removal of various hydrocarbon molecules contained within the gas. Some of these gases include heptane , pentane , propane and other hydrocarbons with molecular weights above methane ( CH 4 ). The natural gas transmission lines extend to the natural gas processing plant or unit which removes
3348-716: Is sometimes informally referred to simply as "gas", especially when it is being compared to other energy sources, such as oil, coal or renewables. However, it is not to be confused with gasoline , which is also shortened in colloquial usage to "gas", especially in North America. Natural gas is measured in standard cubic meters or standard cubic feet . The density compared to air ranges from 0.58 (16.8 g/mole, 0.71 kg per standard cubic meter) to as high as 0.79 (22.9 g/mole, 0.97 kg per scm), but generally less than 0.64 (18.5 g/mole, 0.78 kg per scm). For comparison, pure methane (16.0425 g/mole) has
3441-592: Is still estimated to account for around 250,000 deaths each year, and around 6.4 million childhood asthma cases each year. The hardest hit countries by air pollution from ships are China, Japan, the UK, Indonesia, and Germany. In 2015, shipping air pollution killed an estimated 20,520 people in China, 4,019 people in Japan, and 3,192 people in the UK. According to an ICCT study, countries located on major shipping lanes are particularly exposed, and can see shipping account for
3534-476: Is still the primary fuel for cruise ships , a tourism sector that is associated with a clean and friendly image. In stark contrast, the exhaust gas emissions - due to HFO's high sulfur content - result in an eco balance significantly worse than that for individual mobility. The term " bunkering " broadly relates to storage of petroleum products in tanks (among other, disparate meanings). The precise meaning can be further specialized depending on context. Perhaps
3627-604: Is traded on a "dry gas" basis and is required to be commercially free from objectionable odours, materials, and dust or other solid or liquid matter, waxes, gums and gum forming constituents, which might damage or adversely affect operation of equipment downstream of the custody transfer point. LNG carrier ships transport liquefied natural gas (LNG) across oceans, while tank trucks can carry LNG or compressed natural gas (CNG) over shorter distances. Sea transport using CNG carrier ships that are now under development may be competitive with LNG transport in specific conditions. Gas
3720-409: Is transported at high pressure, typically above 200 bars (20,000 kPa; 2,900 psi). Compressors and decompression equipment are less capital intensive and may be economical in smaller unit sizes than liquefaction/regasification plants. Natural gas trucks and carriers may transport natural gas directly to end-users, or to distribution points such as pipelines. In the past, the natural gas which
3813-416: Is turned into liquid at a liquefaction plant, and is returned to gas form at regasification plant at the terminal . Shipborne regasification equipment is also used. LNG is the preferred form for long distance, high volume transportation of natural gas, whereas pipeline is preferred for transport for distances up to 4,000 km (2,500 mi) over land and approximately half that distance offshore. CNG

3906-480: Is very common in some areas, such as the Northeastern United States . Residual fuel oil is less useful because it is so viscous that it has to be heated with a special heating system before use and it may contain relatively high amounts of pollutants , particularly sulfur , which forms sulfur dioxide upon combustion. However, its undesirable properties make it very cheap. In fact, it is
3999-427: The supply chain can result in natural gas having a similar carbon footprint to other fossil fuels overall. Natural gas can be found in underground geological formations , often alongside other fossil fuels like coal and oil (petroleum). Most natural gas has been created through either biogenic or thermogenic processes. Thermogenic gas takes a much longer period of time to form and is created when organic matter
4092-526: The 1% of its buildings that burned fuel oils No. 4 and No. 6 were responsible for 86% of the soot pollution generated by all buildings in the city. New York made the phase out of these fuel grades part of its environmental plan, PlaNYC, because of concerns for the health effects caused by fine particulates, and all buildings using fuel oil No. 6 had been converted to less polluting fuel by the end of 2015. Residual fuel's use in electrical generation has also decreased. In 1973, residual fuel oil produced 16.8% of
4185-548: The 19th century, natural gas was primarily obtained as a by-product of producing oil . The small, light gas carbon chains came out of solution as the extracted fluids underwent pressure reduction from the reservoir to the surface, similar to uncapping a soft drink bottle where the carbon dioxide effervesces . The gas was often viewed as a by-product, a hazard, and a disposal problem in active oil fields. The large volumes produced could not be used until relatively expensive pipeline and storage facilities were constructed to deliver
4278-406: The 20th century, it was increasingly referred to as simply "gas." In order to highlight its role in exacerbating the climate crisis , however, many organizations have criticized the continued use of the word "natural" in referring to the gas. These advocates prefer the term "fossil gas" or "methane gas" as better conveying to the public its climate threat. A 2020 study of Americans' perceptions of

Classes E to H are residual oils for atomizing burners serving boilers or, with the exception of Class H, certain types of larger combustion engines. Classes F to H invariably require heating prior to use; Class E fuel may require preheating, depending on ambient conditions. Mazut is a residual fuel oil often derived from Russian petroleum sources and
4464-638: The International Marine Organization (IMO) all marine shipping vessels will require the use of very low sulfur fuel oil (0.5% Sulfur) or to install exhaust gas scrubber systems to remove the excess sulfur dioxide. The emissions from ships have generally been controlled by the following sulfur caps on any fuel oil used on board: 3.50% on and after 1 January 2012 and 0.50% on and after 1 January 2020. Further removal of sulfur translates to additional energy and capital costs and can impact fuel price and availability. If priced correctly
4557-432: The US had peaked three times, with current levels exceeding both previous peaks. It reached 24.1 trillion cubic feet per year in 1973, followed by a decline, and reached 24.5 trillion cubic feet in 2001. After a brief drop, withdrawals increased nearly every year since 2006 (owing to the shale gas boom ), with 2017 production at 33.4 trillion cubic feet and 2019 production at 40.7 trillion cubic feet. After
4650-427: The US, over one-third of households (>40 million homes) cook with gas. Natural gas dispensed in a residential setting can generate temperatures in excess of 1,100 °C (2,000 °F) making it a powerful domestic cooking and heating fuel. Stanford scientists estimated that gas stoves emit 0.8–1.3% of the gas they use as unburned methane and that total U.S. stove emissions are 28.1 gigagrams of methane. In much of
4743-523: The United States begins with localized use. In the seventeenth century, French missionaries witnessed the American Indians setting fire to natural gas seeps around lake Erie, and scattered observations of these seeps were made by European-descended settlers throughout the eastern seaboard through the 1700s. In 1821, William Hart dug the first commercial natural gas well in the United States at Fredonia, New York , United States, which led in 1858 to

Some parameters of marine fuel oils according to ISO 8217 (3. ed 2005): Bunker fuel or bunker crude is technically any type of fuel oil used aboard water vessels . Its name is derived from coal bunkers, where the fuel was originally stored. In 2019, large ships consumed 213 million metric tons of bunker fuel. The Australian Customs and the Australian Tax Office defines
4929-702: The bottoms of the gashouse ovens was often used for roofing and other waterproofing purposes, and when mixed with sand and gravel was used for paving streets. Huge quantities of natural gas (primarily methane) exist in the form of clathrates under sediment on offshore continental shelves and on land in arctic regions that experience permafrost , such as those in Siberia . Hydrates require a combination of high pressure and low temperature to form. In 2013, Japan Oil, Gas and Metals National Corporation (JOGMEC) announced that they had recovered commercially relevant quantities of natural gas from methane hydrate. The image below
5022-429: The cheapest liquid fuel available. Since it requires heating before use, residual fuel oil cannot be used in road vehicles, boats or small ships, as the heating equipment takes up valuable space and makes the vehicle heavier. Heating the oil is also a delicate procedure, which is impractical on small, fast moving vehicles. However, power plants and large ships are able to use residual fuel oil. Use of residual fuel oil

By 1983, it had fallen to 6.2%, and as of 2005 , electricity production from all forms of petroleum, including diesel and residual fuel, is only 3% of total production. The decline is the result of price competition with natural gas and environmental restrictions on emissions. For power plants, the costs of heating the oil, extra pollution control and additional maintenance required after burning it often outweigh

Natural gas can come out of the ground and cause a long-burning fire. In ancient Greece , the gas flames at Mount Chimaera contributed to the legend of the fire-breathing creature Chimera . In ancient China , gas resulting from the drilling for brines was first used by about 400 BC. The Chinese transported gas seeping from
6045-448: The fuels most frequently quoted are listed below in order of cost, the least expensive first. The density is also an important parameter for fuel oils since marine fuels are purified before use to remove water and dirt from the oil. Since the purifiers use centrifugal force , the oil must have a density which is sufficiently different from water. Older purifiers work with a fuel having a maximum of 991 kg/m3; with modern purifiers it
6138-435: The gas needs to be cooled down and compressed, as the friction in the pipeline causes the gas to heat up. Many existing pipelines in the US are close to reaching their capacity, prompting some politicians representing northern states to speak of potential shortages. The large trade cost implies that natural gas markets are globally much less integrated, causing significant price differences across countries. In Western Europe ,
6231-517: The gas pipeline network is already dense. New pipelines are planned or under construction between Western Europe and the Near East or Northern Africa . Whenever gas is bought or sold at custody transfer points, rules and agreements are made regarding the gas quality. These may include the maximum allowable concentration of CO 2 , H 2 S and H 2 O . Usually sales quality gas that has been treated to remove contamination
6324-896: The gas to consumer markets. Until the early part of the 20th century, most natural gas associated with oil was either simply released or burned off at oil fields. Gas venting and production flaring are still practised in modern times, but efforts are ongoing around the world to retire them, and to replace them with other commercially viable and useful alternatives. In addition to transporting gas via pipelines for use in power generation, other end uses for natural gas include export as liquefied natural gas (LNG) or conversion of natural gas into other liquid products via gas to liquids (GTL) technologies. GTL technologies can convert natural gas into liquids products such as gasoline, diesel or jet fuel. A variety of GTL technologies have been developed, including Fischer–Tropsch (F–T), methanol to gasoline (MTG) and syngas to gasoline plus (STG+). F–T produces
6417-526: The ground in crude pipelines of bamboo to where it was used to boil salt water to extract the salt in the Ziliujing District of Sichuan . Natural gas was not widely used before the development of long distance pipelines in the early twentieth century. Before that, most use was near to the source of the well, and the predominant gas for fuel and lighting during the industrial revolution was manufactured coal gas. The history of natural gas in
6510-503: The heaviest oil must be heated for it to flow. Price usually decreases as the fuel number increases. Number 1 fuel oil is a volatile distillate oil intended for vaporizing pot-type burners and high-performance/clean diesel engines. It is the kerosene refinery cut that boils off immediately after the heavy naphtha cut used for gasoline . This fuel is commonly known as diesel no. 1 , kerosene , and jet fuel . Former names include: coal oil, stove oil, and range oil. Number 2 fuel oil
6603-548: The high viscosity requires heating, usually by a recirculated low pressure steam system, before the oil can be pumped from a bunker tank. Bunkers are rarely labeled this way in modern maritime practice. Since the 1980s the International Organization for Standardization (ISO) has been the accepted standard for marine fuels (bunkers). The standard is listed under number 8217, with recent updates in 2010 and 2017. The latest edition of bunker fuel specification
6696-442: The higher-molecular weight hydrocarbons to produce natural gas with energy content between 35–39 megajoules per cubic metre (950–1,050 British thermal units per cubic foot). The processed natural gas may then be used for residential, commercial and industrial uses. Natural gas flowing in the distribution lines is called mid-stream natural gas and is often used to power engines which rotate compressors. These compressors are required in
6789-455: The ignition quality of residual fuel oil, and CCAI is especially often calculated for marine fuels. Despite this, marine fuels are still quoted on the international bunker markets with their maximum viscosity (which is set by the ISO 8217 standard - see below) due to the fact that marine engines are designed to use different viscosities of fuel. The unit of viscosity used is the centistoke (cSt) and
6882-458: The internal condensation produced sulfuric acid . Environmental cleanups at such facilities are frequently complicated by the use of asbestos insulation on the fuel feed lines. No. 6 oil is very persistent, and does not degrade rapidly. Its viscosity and stickiness also make remediation of underground contamination very difficult, since these properties reduce the effectiveness of methods such as air stripping . When released into water, such as
6975-612: The largest proven gas reserves. Sources that consider that Russia has by far the largest proven reserves include the US Central Intelligence Agency (47,600 km ) and Energy Information Administration (47,800 km ), as well as the Organization of Petroleum Exporting Countries (48,700 km ). Contrarily, BP credits Russia with only 32,900 km , which would place it in second, slightly behind Iran (33,100 to 33,800 km , depending on
7068-457: The low cost of the fuel. Burning fuel oil, particularly residual fuel oil, produces uniformly higher carbon dioxide emissions than natural gas. Heavy fuel oils continue to be used in the boiler "lighting up" facility in many coal-fired power plants. This use is approximately analogous to using kindling to start a fire. Without performing this act it is difficult to begin the large-scale combustion process. The chief drawback to residual fuel oil
7161-499: The low quality of bunker fuel, when burnt it is especially harmful to the health of humans, causing serious illnesses and deaths. Prior to the IMO's 2020 sulfur cap, shipping industry air pollution was estimated to cause around 400,000 premature deaths each year, from lung cancer and cardiovascular disease, as well as 14 million childhood asthma cases each year. Even after the introduction of cleaner fuel rules in 2020, shipping air pollution
7254-399: The most common, more specialized usage refers to the practice and business of refueling ships. Bunkering operations are located at seaports, and they include the storage of bunker (ship) fuels and the provision of the fuel to vessels. Alternatively "bunkering" may apply to the shipboard logistics of loading fuel and distributing it among available bunkers (on-board fuel tanks). Finally, in
7347-433: The natural gas can be transported. Natural gas extracted from oil wells is called casinghead gas (whether or not truly produced up the annulus and through a casinghead outlet) or associated gas. The natural gas industry is extracting an increasing quantity of gas from challenging, unconventional resource types : sour gas , tight gas , shale gas , and coalbed methane . There is some disagreement on which country has
7440-441: The pores of the gas reservoir get depleted. One method to deal with this problem is to re-inject dried gas free of condensate to maintain the underground pressure and to allow re-evaporation and extraction of condensates. More frequently, the liquid condenses at the surface, and one of the tasks of the gas plant is to collect this condensate. The resulting liquid is called natural gas liquid (NGL) and has commercial value. Shale gas
7533-523: The refinery's production was halted by the attack. Fuel oil Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel , and others. The term fuel oil generally includes any liquid fuel that
7626-434: The ships of the single largest cruise company, Carnival Corporation & plc , emitted ten times more sulfur dioxide than all of Europe's cars combined. Although the following trends generally hold true, different organizations may have different numerical specifications for the six fuel grades. The boiling point and carbon chain length of the fuel increases with fuel oil number. Viscosity also increases with number, and
7719-550: The source). It is estimated that there are about 900,000 km of "unconventional" gas such as shale gas, of which 180,000 km may be recoverable. In turn, many studies from MIT , Black & Veatch and the US Department of Energy predict that natural gas will account for a larger portion of electricity generation and heat in the future. The world's largest gas field is the offshore South Pars / North Dome Gas-Condensate field , shared between Iran and Qatar. It
7812-414: The start of the fractional distillation process. Heavier petroleum-derived oils like diesel fuel and lubricating oil are much less volatile and distill out more slowly. Oil has many uses; it heats homes and businesses and fuels trucks , ships , and some cars . A small amount of electricity is produced by diesel, but it is more polluting and more expensive than natural gas . It is often used as
7905-521: The sulfur content requirement outside the ECAs to 0.5% m/m by 2020. This is where Marine Distillate Fuels and other alternatives to use of heavy bunker fuel come into play. They have similar properties to diesel #2, which is used as road diesel around the world. The most common grades used in shipping are DMA and DMB. Greenhouse gas emissions resulting from the use of international bunker fuels are currently included in national inventories. Heavy fuel oil
7998-654: The third peak in December 2019, extraction continued to fall from March onward due to decreased demand caused by the COVID-19 pandemic in the US . The 2021 global energy crisis was driven by a global surge in demand as the world quit the economic recession caused by COVID-19, particularly due to strong energy demand in Asia. Because of its low density, it is not easy to store natural gas or to transport it by vehicle. Natural gas pipelines are impractical across oceans, since
8091-412: The transmission line to pressurize and repressurize the mid-stream natural gas as the gas travels. Typically, natural gas powered engines require 35–39 MJ/m (950–1,050 BTU/cu ft) natural gas to operate at the rotational name plate specifications. Several methods are used to remove these higher molecular weighted gases for use by the natural gas engine. A few technologies are as follows: In
8184-507: The world, e.g. , California, European Union, have established Emission Control Areas (ECA) that limit the maximum sulfur of fuels burned in their ports to limit pollution, reducing the percentage of sulfur and other particulates from 4.5% m/m to as little as 0.10% as of 2015 inside an ECA. As of 2013 3.5% continued to be permitted outside an ECA, but the International Maritime Organization has planned to lower
8277-449: The worldwide extraction, access to natural gas has become an important issue in international politics, and countries vie for control of pipelines. In the first decade of the 21st century, Gazprom , the state-owned energy company in Russia, engaged in disputes with Ukraine and Belarus over the price of natural gas, which have created concerns that gas deliveries to parts of Europe could be cut off for political reasons. The United States
8370-426: Was a distillate oil for burners requiring low-viscosity fuel. ASTM merged this grade into the number 2 specification, and the term has been rarely used since the mid-20th century. Number 4 fuel oil is a commercial heating oil for burner installations not equipped with preheaters. It may be obtained from the heavy gas oil cut. This fuel is sometimes known by the Navy specification of Bunker A . Number 5 fuel oil
8463-494: Was invented in Saudi Arabia in the late 1970s, ending any necessity for flaring. Satellite and nearby infra-red camera observations, however, shows that flaring and venting are still happening in some countries. Natural gas is used to generate electricity and heat for desalination . Similarly, some landfills that also discharge methane gases have been set up to capture the methane and generate electricity. Natural gas
8556-622: Was more common in the past. It powered boilers , railroad steam locomotives , and steamships . Locomotives, however, have become powered by diesel or electric power; steamships are not as common as they were previously due to their higher operating costs (most LNG carriers use steam plants, as "boil-off" gas emitted from the cargo can be used as a fuel source); and most boilers now use heating oil or natural gas. Some industrial boilers still use it and so do some old buildings, including in New York City . In 2011 New York City estimated that
8649-567: Was recovered in the course of recovering petroleum could not be profitably sold, and was simply burned at the oil field in a process known as flaring . Flaring is now illegal in many countries. Additionally, higher demand in the last 20–30 years has made production of gas associated with oil economically viable. As a further option, the gas is now sometimes re- injected into the formation for enhanced oil recovery by pressure maintenance as well as miscible or immiscible flooding. Conservation, re-injection, or flaring of natural gas associated with oil
