117-518: The formerly agrarian town today has one of the largest oil refineries ( PCK Raffinerie GmbH ) in Germany, established in 1958 and connected to the Russian Druzhba pipeline network. The refinery uses 20 million cubic meters of water per year for the process. A large paper factory ( UPM ) is located near Schwedt. Most industries were located in the remote area during communist rule in

234-402: 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

351-786: A German-ethnicity sovereign state , within what today comprises Germany, occurred in 1778 as the state flag of the Principality of Reuss-Greiz , a defunct principality in the modern state's borders. Some reordering of the Thuringian states occurred during the German Mediatisation from 1795 to 1814, and the territory was included within the Napoleonic Confederation of the Rhine organized in 1806. The 1815 Congress of Vienna confirmed these changes and

468-632: 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

585-761: 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

702-800: 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

819-428: 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

936-430: 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

1053-645: 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

1170-658: 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

1287-711: A minimum voting age of 21. Between 1920 and 1932, under the Weimar Republic , six Landtag elections were held. Thuringia was one of the states where the Nazi Party first gained real political power during the Weimar Republic. Wilhelm Frick was appointed Minister of the Interior in the state coalition government after the Nazi Party won six deputies to the Thuringian Landtag in

1404-462: 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

1521-551: 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

1638-447: A strong tendency from rural areas towards the big cities. From 2008 to 2012, there was a net migration from Thuringia to Erfurt of +6,700 persons (33 per 1000 inhabitants), +1,800 to Gera (19 per 1000), +1,400 to Jena (14 per 1000), +1,400 to Eisenach (33 per 1000) and +1,300 to Weimar (21 per 1000). Between Thuringia and the other German states, the balance is negative: In 2012, Thuringia lost 6,500 persons to other federal states,

1755-538: A well-equipped winter sports destination – half of Germany's 136 Winter Olympic gold medals had been won by Thuringian athletes as of 2014. Thuringia was favoured by or was the birthplace of three key intellectuals and leaders in the arts: Johann Sebastian Bach , Johann Wolfgang von Goethe , and Friedrich Schiller . The state has the University of Jena , the Ilmenau University of Technology ,

1872-504: Is temperate with humid westerly winds predominating. Increasingly as one moves from the north-west to the south-east, the climate shows continental features: winters can be cold for long periods, and summers can become warm. Dry periods are often recorded, especially within the Thuringian Basin, leeward to mountains in all directions. It is Germany's driest area, with annual precipitation of only 400 to 500 mm. Artern , in

1989-469: Is about 1.78% less. The current population is 2,120,237 (31 December 2020) with an annual rate of decrease of about 0.5%, which varies widely between the local regions. In 2012, 905,000 Thuringians lived in a municipality with more than 20,000 inhabitants, this is an urbanization rate of 42% which continues to rise. In July 2013, there were 41,000 non-Germans by citizenship living in Thuringia (1.9% of

2106-471: Is among the 10 largest German municipalities by area (9th as of Nov. 2023). Gartz (Germany), Penkun (Germany), Szczecin (Poland), Gryfino (Poland), Cedynia (Poland), Chojna (Poland), Mieszkowice (Poland), Moryń (Poland), Trzcińsko-Zdrój (Poland), Myślibórz (Poland), Pyrzyce (Poland). After the Migration Period , the area had been settled by Polabian Slavs . From 937 onwards

2223-433: 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

2340-593: Is bordered by Bavaria , Hesse , Lower Saxony , Saxony-Anhalt , and Saxony . It has been known as "the green heart of Germany" ( das grüne Herz Deutschlands ) from the late 19th century due to its broad, dense forest. Most of Thuringia is in the Saale drainage basin , a left-bank tributary of the Elbe . Thuringia is home to the Rennsteig , Germany's best-known hiking trail . Its winter resort of Oberhof makes it

2457-408: 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

2574-551: Is forest with beech as its predominant species, as can still be found in the Hainich mountains today. In the uplands, a mixture of beech and spruce would be natural. However, most of the plains have been cleared and are in intensive agricultural use while most of the forests are planted with spruce and pine . Since 1990, Thuringia's forests have been managed aiming for a more natural and tough vegetation more resilient to climate change as well as diseases and vermin. In comparison to

2691-470: Is now Thuringia were the Sorbs proper , who unified all tribes in what is now southern half of Eastern Germany. The Ostsiedlung movement led to the assimilation of Slavic people between the 11th and the 13th century under German rule. The population growth increased during the 18th century and stayed high until World War I , before it slowed within the 20th century and changed to a decline since 1990. Since

2808-424: 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

2925-413: 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)

3042-806: Is situated in the east of the historic Uckermark region stretching from the Oder to the Havel River. It is situated on a sandur at the western edge of the Oder floodplain running along the German-Polish border , which in 1995 was declared as the Lower Oder Valley National Park nature reserve. Across the river and the border, about 10 km (6.2 mi) to the southeast, is the Polish town of Chojna . The nearest German towns are Angermünde (about 18 km (11 mi) to

3159-475: 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

3276-718: The Bratwurst and the Forest , because a large amount of the territory is forested. Named after the Thuringii Germanic tribe who occupied it around AD 300, Thuringia came under Frankish domination in the 6th century. Thuringia became a landgraviate in 1130 AD. After the extinction of the reigning Ludowingian line of counts and landgraves in 1247 and the War of the Thuringian Succession (1247–1264),

3393-648: 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

3510-564: 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,

3744-685: The German Democratic Republic in 1949, but was dissolved in 1952 during administrative reforms , and divided into the Districts of Erfurt , Suhl and Gera . Thuringia was re-established in 1990 following German reunification , slightly re-drawn, and became one of the new states of the Federal Republic of Germany. The name Thuringia or Thüringen derives from the Germanic tribe Thuringii , who emerged during

3861-851: The German Peasants' War of 1525. In Mühlhausen and elsewhere, the Anabaptists found many adherents. Thomas Müntzer , a leader of some non-peaceful groups of this sect, was active in this city. Within the borders of modern Thuringia the Roman Catholic faith only survived in the Eichsfeld district, which was ruled by the Archbishop of Mainz , and to a small degree in Erfurt and its immediate vicinity. The modern German black-red-gold tricolour flag's first appearance anywhere in

The north-west includes the Eichsfeld , a hilly and sometimes forested region, where the Leine river emanates. The central and northern part of Thuringia is defined by the 3,000 km (1,200 sq mi) wide Thuringian Basin , a very fertile and flat area around the Unstrut river and completely surrounded by

4095-637: The Goldisthal Pumped Storage Station in the Thuringian Highlands. Thuringia is Germany's only state with no connection to navigable waterways. The geographic centre of the Federal Republic is in Thuringia, within the municipality of Vogtei next to Mühlhausen . The centre of Thuringia is eight kilometres south of the capital's Cathedral , in the municipality of Rockhausen . Thuringia's climate

4212-645: The Migration Period . Their origin is largely unknown. An older theory claims that they were successors of the Hermunduri , but later research rejected the idea. Other historians argue that the Thuringians were allies of the Huns , came to central Europe together with them, and lived before in what is Galicia today. Publius Flavius Vegetius Renatus first mentioned the Thuringii around 400; during that period,

4329-764: The Rhön Mountains around Geisa in the southwest. Protestant church membership is shrinking rapidly, whereas the Catholic Church is somewhat more stable because of Catholic migration from Poland, Southern Europe and West Germany. Other religions play no significant role in Thuringia. There are only a few thousand Muslims (largely migrants) and about 750 Jews (mostly migrants from Russia) living in Thuringia. Furthermore, there are some Orthodox communities of Eastern European migrants and some traditional Protestant Free churches in Thuringia without any societal influence. The Protestant parishes of Thuringia belong to

4446-725: The University of Erfurt , and the Bauhaus University of Weimar . The Frankish Duchy of Thuringia was established around 631 AD by King Dagobert I . The modern state was established in 1920 by the Weimar Republic through a merger of the Ernestine duchies , save for Saxe-Coburg . After World War II , Thuringia came under the Soviet occupation zone in Allied-occupied Germany , and its borders were reformed, to become contiguous . Thuringia became part of

4563-544: The Vogtland , a hilly but in most parts non-forested region in the south. The far eastern region (east of White Elster) is the Osterland or Altenburger Land along Pleiße river, a flat, fertile and densely settled agricultural area. There are two large rivers in Thuringia. The Saale , a tributary of the Elbe , with its tributaries the Unstrut , Ilm and White Elster, drains the most part of Thuringia. The Werra –

4680-595: The electoral threshold of 5%. The other two parties of the traffic light coalition in Berlin, Greens and the Free Democratic Party (FDP), did not pass the threshold and lost all of their seats, which contributed to the break-up of that coalition on November 6th. The Christian Democratic Union (CDU) recorded small gains and came second with 24%. The newly-founded Sahra Wagenknecht Alliance BSW debuted in third place at 16%. The AfD in Thuringia became

4797-493: 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 .

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

5148-408: 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

5265-399: 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

5382-793: The " Law on the Reconstruction of the Reich " of 30 January 1934, which replaced the German federal system with a unitary state . Thuringia was the location of the Buchenwald concentration camp with multiple subcamps. After being controlled briefly by the US following the end of the Second World War , from July 1945 the state of Thuringia came under the Soviet occupation zone and was expanded to include parts of Prussian Saxony, such as

5499-628: 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

5616-860: 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

5733-460: The 1960s and 1970s. Large residential areas were built for the workers moving to Schwedt. About 9% of the town's flats are in prefab concrete buildings ( Plattenbau ) dating from the era. As many jobs were lost after German reunification and the return to market economy, Schwedt has lost a quarter of its population since 1990. In recent decades, Schwedt became a model town for the demolition of Plattenbau housing to combat urban decay . Schwedt

5850-788: The 1960s, the government of the DDR expanded housing and encouraged people to move to Schwedt, a trend that ended with German reunification . Since 1990, Schwedt is again part of the State of Brandenburg. Schwedt is twinned with: Oil refinery An oil refinery or petroleum refinery 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

5967-551: The 2011 Census results. Since the Protestant Reformation , the most prominent Christian denomination in Thuringia has been Lutheranism . During the GDR period, church membership was discouraged and has continued shrinking since the reunification in 1990. Today over two thirds of the population is non-religious. The Protestant Church in Germany has had the largest number of members in the state, adhered to by 20.8% of

6084-589: The Austro-Hungarian Empire (now in Poland ) in 1854. The first large refinery opened at Ploiești , Romania, in 1856–1857. It was in Ploiesti that, 51 years later, in 1908, Lazăr Edeleanu , a Romanian chemist of Jewish origin who got his PhD in 1887 by discovering amphetamine , invented, patented and tested on industrial scale the first modern method of liquid extraction for refining crude oil,

6201-691: The Bear again invaded the lands on the Oder river, which remained disputed between the newly established Margraviate of Brandenburg and the Pomeranian dukes . The settlement of Schwedt was first mentioned in a 1265 deed. In the course of the Brandenburg–Pomeranian conflict , the Brandenburg margrave Louis II the Roman ceded it to Duke Barnim III of Pomerania in 1354. It was again besieged by

6318-523: The City of Edmonton , which has a population of over 1,000,000 residents. NIOSH criteria for occupational exposure to refined petroleum solvents have been available since 1977. 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

6435-405: The December 1929 election. In this position, he removed from the Thuringian police force anyone he suspected of being a republican and replaced them with men who were favourable towards the Nazis. He also ensured that, whenever an important position came up within Thuringia, a Nazi was given that post. Following the Nazi seizure of power in Berlin, the Landtag was formally abolished as a result of

6552-431: The Ludowingian Landgraves of 12th-century origin. The eight stars around it represent the eight former states which formed Thuringia. The flag of Thuringia is a white-red bicolor, derived from the white and red stripes of the Ludowingian lion. The coat of arms and flag of Hesse are quite similar to the Thuringian ones, since they are also derived from the Ludowingian symbols. Symbols of Thuringia in popular culture are

6669-446: The Thuringian states' inclusion in the German Confederation ; the Kingdom of Prussia also acquired some Thuringian territory and administered it within the Province of Saxony . The Thuringian duchies which became part of the German Empire in 1871 during the Prussian-led unification of Germany were Saxe-Weimar-Eisenach , Saxe-Meiningen , Saxe-Altenburg , Saxe-Coburg-Gotha , Schwarzburg-Sondershausen , Schwarzburg-Rudolstadt and

6786-422: The Thuringii were famous for their excellent horses. The Thuringian Realm existed until after 531. The Landgraviate of Thuringia was the largest state in the region, persisting between 1131 and 1247. Afterwards the state known as Thuringia ceased to exist; nevertheless the term commonly described the region between the Harz mountains in the north, the White Elster river in the east, the Franconian Forest in

6903-523: 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

7254-403: The areas around Erfurt , Mühlhausen , and Nordhausen . Erfurt became the new capital of Thuringia. Ostheim , an exclave of Landkreis Eisenach, was ceded to Bavaria. In 1952, the German Democratic Republic dissolved its states, and created districts ( Bezirke ) instead. The three districts that shared the former territory of Thuringia were Erfurt, Gera and Suhl . Altenburg Kreis

7371-415: The balance was negative with Switzerland (−2,800) and Austria (−900). Of the approximately 850 municipalities of Thuringia, 126 are classed as towns (within a district) or cities (forming their own urban district). Most of the towns are small with a population of less than 10,000; only the ten biggest ones have a population greater than 30,000. The first towns emerged during the 12th century, whereas

7488-408: The beginning of Urbanisation around 1840, the Thuringian cities have higher growth rates resp. smaller rates of decline than rural areas (many villages lost half of their population since 1950, whereas the biggest cities ( Erfurt and Jena ) kept growing). The 1981 census projected that Thuringia's population would reach 2,221,222 by 2011. The population counted in the 2011 census was 2,181,603, which

7605-415: The birth ratio. Furthermore, the population is getting older and older with some rural municipalities recording more than 30% of over-65s (pensioners). This is a problem for the regional labour market, as there are twice as many people leaving as entering the job market annually. The birth rate was about 1.8 children per women in the 1970s and 1980s, shrinking to 0.8 in 1994 during the economic crisis after

7722-426: The college towns Erfurt , Jena , Weimar and Ilmenau have the highest rates, whereas there are almost no migrants living in the most rural smaller municipalities. The Thuringian population has a significant sex ratio gap, caused by the emigration of young women, especially in rural areas. Overall, there are 115 to 120 men per 100 women in the 25–40 age group ("family founders") which has negative consequences for

7839-427: 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

7956-555: 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 ,

8073-667: 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

8190-487: 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

8307-573: The economy has seen an upturn and the general economic situation has improved. Agriculture and forestry have declined in importance over the decades. Nevertheless, they are more important than in most other areas of Germany, especially within rural regions. 54% of Thuringia's territory is in agricultural use. The fertile basins such as the large Thuringian Basin or the smaller Goldene Aue , Orlasenke and Osterland are in intensive use for growing cereals, vegetables, fruits and energy crops. Important products are apples, strawberries, cherries and plums in

8424-443: 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

8541-525: The first Hohenzollern margrave Frederick I in 1434, but to no avail. In 1481 the Thuringian counts of Hohnstein acquired the estates; they granted town privileges to Schwedt as well as to neighbouring Vierraden and introduced the Protestant Reformation . The rise of Schwedt came to an end with the extinction of the Hohnstein counts in 1609 and the disastrous Thirty Years' War , when the town on

8658-472: The first far-right party in Germany since World War II to win a state election. Thuringia is divided into 17 districts ( Landkreise ): Furthermore, there are five urban districts: Thuringia's economy is marked by the economic transition that happened after the German reunification and led to the closure of most of the factories within the Land. The unemployment rate reached a peak in 2005. Since that year,

8775-525: The following hill chains (clockwise from the north-west): Dün , Hainleite , Windleite , Kyffhäuser , Hohe Schrecke , Schmücke , Finne , Ettersberg , Steigerwald , Thuringian Forest , Hörselberge and Hainich . Within the Basin the smaller hill chains Fahner Höhe and Heilinger Höhen . South of the Thuringian Basin is the state's largest mountain range, marked by the Thuringian Forest in

8892-440: The forest, agriculture is still quite conventional and dominated by large structures and monocultures. Problems here are caused especially by increasingly prolonged dry periods during the summer months. Environmental damage in Thuringia has been reduced to a large extent after 1990. The condition of forests, rivers and air was improved by modernizing factories, houses (decline of coal heating) and cars, and contaminated areas such as

9009-751: The forested mountains, are protected as natural reserves, including Thuringia's first national park within the Hainich mountains, founded in 1997, the Rhön Biosphere Reserve , the Thuringian Forest Nature Park and the South Harz Nature Park . During the Middle Ages, Thuringia was at the border between Germanic and Slavic territories, marked by the Saale river. The main Slavic tribe in what

9126-461: The former Uranium surface mines around Ronneburg have been remediated. Today's environmental problems are the salination of the Werra river, caused by discharges of K+S salt mines around Unterbreizbach and overfertilisation in agriculture, damaging the soil and small rivers. Environment and nature protection has been of growing importance and attention since 1990. Large areas, especially within

9243-412: 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

9360-816: The headwater of the Weser – drains the south-west and west of the state. Furthermore, some small areas on the southern border are drained by tributaries of the Main , itself a tributary of the Rhine . There are no large natural lakes in Thuringia, but it does have some of Germany's biggest dams, including the Bleiloch Dam and the Hohenwarte Dam on the River Saale, as well as the Leibis-Lichte Dam and

9477-514: 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

9594-542: 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

9711-480: 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,

9828-652: The lands of the Slavic Ukrani tribes in the west were subdued by the Saxon forces of Margrave Gero and incorporated into his vast Marca Geronis , while the lands east of the Oder were held by Pomeranian tribes under sovereignty of the newly formed Duchy of Poland ruled by Duke Mieszko I . The Saxon Northern March was lost in the Great Slav Rising of 983, and not before 1147 the Saxon count Albert

9945-619: The largest party with 33% of the vote (and 36% of the seats), its best ever performance and the first time it placed first in a state election in Germany. The incumbent governing coalition suffered dramatic losses; the Left had split up, with new Sahra Wagenknecht Alliance (BSW) becoming the more popular part, while the remaining Left lost more than half of its support and fell to fourth place on 13%. The 130+ year old SPD, which since late 2021 rules Germany under Chancellor Olaf Scholz, recorded its worst result in any postwar state election, barely passing

10062-621: 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

10179-417: The latest ones received town status only in the 20th century. Today, all municipalities within districts are equal in law, whether they are towns or villages. Independent cities (i.e. urban districts) have greater powers (the same as any district) than towns within a district. * Average annual change in percent within the last three years (13 December 2009 to 31 December 2012), adjusted from incorporations and

10296-411: 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,

10413-415: 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

10530-436: 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

10647-460: The most to Bavaria , Saxony , Hesse and Berlin . Only with Saxony-Anhalt and Brandenburg the balance is positive. The international migration is fluctuating heavily. In 2009, the balance was +700, in 2010 +1,800, in 2011 +2,700 and in 2012 +4,800. The most important countries of origin of the Thuringia migrants from 2008 to 2012 were Poland (+1,700), Romania (+1,200), Afghanistan (+1,100) and Serbia / Montenegro / Kosovo (+1,000), whereas

10764-753: 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 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,

10881-487: 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

10998-493: The north-east, is warm and dry, with a mean annual temperature of 8.5 °C and mean precipitation of 450 mm; contrast this with wet, cool Oberhof , in the Thuringian Forest, where temperature averages only 4.4 °C and mean annual precipitation reaches 1300 mm. Due to many centuries of intensive settlement, most of the area is shaped by human influence. The original natural vegetation of Thuringia

11115-709: The north-west, the Thuringian Highland in the middle and the Franconian Forest in the south-east. Most of this range is forested and the Großer Beerberg (983 m) is Thuringia's highest mountain. To the south-west, the Forest is followed up by Werra river valley, dividing it from the Rhön Mountains in the west and the Grabfeld plain in the south. Eastern Thuringia, commonly described as

11232-463: The party got 22.7%, while in 2021 they got 24.0%. Thuringia is notable for being the first and only state in Germany where the communist party that ruled former East Germany until 1989, The Left (Die Linke), and the new Alternative for Germany (AfD) have seen their first-ever first place finish in a state election. Die Linke in 2019 , and the AfD in 2024 . The Alternative for Germany (AfD) became

11349-514: The population in 2018. Members of the Catholic Church formed 7.6% of the population, while 71.6% of Thuringians were non-religious or adhere to other faiths. The highest Protestant concentrations are in the small villages of southern and western Thuringia, whereas the bigger cities are even more non-religious (up to 88% in Gera ). Catholic regions are Eichsfeld in the northwest and parts of

11466-569: The population − among the smallest proportions of any state in Germany). Nevertheless, the number rose from 33,000 in July 2011, an increase of 24% in only two years. About 4% of the population are migrants (including persons that already received German citizenship). The biggest groups of foreigners by citizenship are (as of 2012): Russians (3,100), Poles (3,000), Turks (2,100) and Ukrainians (2,000). The number of foreigners varies between regions:

11583-464: 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

11700-455: 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,

11817-626: 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

11934-477: The reunification and rose again to more than 1.4 children in 2010, which is a higher level than in West Germany. Nevertheless, there are only 17,000 births compared to 27,000 deaths per year, so that the annual natural change of the Thuringian population is about −0.45%. In 2015 there were 17,934 births, the highest number since 1990. Migration plays an important role in Thuringia. The internal migration shows

12051-707: The road from Stettin to Berlin was plundered several times. In 1631 King Gustavus Adolphus of Sweden , after landing in Pomerania, camped here on his way to the Battle of Breitenfeld . Six years later the Swedish field marshal Johan Banér set the town on fire, after its citizens refused to capitulate. During the Great Northern War , the Treaty of Schwedt was signed in the town. From 1815 to 1945, Schwedt

12168-536: The south and the Werra river in the west. After the Treaty of Leipzig , Thuringia had its own dynasty again, the Ernestine Wettins . Their various lands formed the Free State of Thuringia, founded in 1920, together with some other small principalities. The Prussian territories around Erfurt , Mühlhausen and Nordhausen joined Thuringia in 1945. The coat of arms of Thuringia shows the lion of

12285-609: 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

12402-458: 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

12519-621: 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

12636-649: The two principalities of Reuss Elder Line and Reuss Younger Line . In 1920, after World War I , these small states merged into one state, called the Free State of Thuringia ( Freistaat Thüringen ); only Saxe-Coburg voted to join Bavaria instead. Weimar became the new capital. The coat of arms of this new state was simpler than those of its predecessors. The Landtag of the newly established state first convened in 1920 in Weimar. Its deputies were elected for three years according to proportional representation , with

12753-420: 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

12870-628: The west) and Gartz (18 km (11 mi) down the Oder). In a 1974 municipal reform, the neighbouring village of Heinersdorf was incorporated into Schwedt, followed by Blumenhagen, Gatow and Kunow in 1993, by Kummerow in 1998, by Criewen and Zützen in 2001, Stendell in 2002, the former town Vierraden in 2003, Schöneberg in January 2021 and Berkholz-Meyenburg , Mark Landin and Passow in April 2022. With 360.73 km (139.28 sq mi) Schwedt

12987-481: The western half became independent under the name of " Hesse ", never to become a part of Thuringia again. Most of the remaining Thuringia came under the rule of the Wettin dynasty of the nearby Margraviate of Meissen , the nucleus of the later Electorate and Kingdom of Saxony . With the division of the house of Wettin in 1485, Thuringia went to the senior Ernestine branch of the family, which subsequently subdivided

13104-601: 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

13221-496: Was also weak, with the evidence primarily centering around neighborhoods in developed countries . Thuringia Thuringia , officially the Free State of Thuringia , is one of Germany's 16 states with 2.1 million people, its 12th-largest by population, and with 16,171 square kilometers, its 11th-largest in area. Erfurt is the capital and largest city. Other cities include Jena , Gera and Weimar . Thuringia

13338-503: 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

13455-453: Was part of Leipzig Bezirk. The present State of Thuringia was recreated with slightly altered borders during German reunification in 1990. From the northwest going clockwise; Thuringia borders on the German states of Lower Saxony , Saxony-Anhalt , Saxony , Bavaria and Hesse . The landscapes of Thuringia are quite diverse. The far north is occupied by the Harz mountains, followed by

13572-640: Was part of the Prussian Province of Brandenburg . Near the end of World War II , over two months of heavy fighting destroyed an estimated 85 percent of the town, including the Schwedt Castle. The Soviet Army occupied Schwedt on April 26, 1945, two weeks before the final defeat of Nazi Germany. From 1945 to 1952, Schwedt was part of the state of Brandenburg and from 1952 to 1990 of the Bezirk Frankfurt of East Germany . During

13689-846: 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
