Fitzgerald , Isaac and Herman Waterman, William Spencer and his sons William and Charles, Thomas and Edward Hodgins, John Geary, Joseph Fallows, John Minhinnick, William English and John Walker. Together, the shareholders possessed twelve oil refineries and controlled 85% of
312-632: 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
390-748: 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
468-640: A cheaper and higher quality product. In 1893, Ottawa reduced import duties on refined oil products from 7.2 cents to 6 cents per wine gallon , and in 1896, Wilfrid Laurier's government reduced the tariff again to 5 cents. Additionally, Laurier removed restrictions on tank cars and tank steamers, allowing foreign companies to bulk ship oil into Canada by rail or sea. Before, foreign companies had to repackage their product into oil barrels before entering Canada, adding roughly five cents in shipping and handling charges to each gallon of imported oil. In 1895, Imperial Oil's Board of Directors began negotiations to sell
546-739: A deal for the Esso-branded stations to join the PC Optimum rewards program, beginning on June 1, 2018. Loblaw Companies had sold its network of 213 gas stations (all of which are attached to its various grocery store locations) to Brookfield Business Partners in 2017; Brookfield entered into an agreement with Imperial Oil to use the Mobil brand for these stations. As part of the sale agreement, these stations also continue to participate in PC Optimum. Oil refinery An oil refinery or petroleum refinery
624-609: A dividend of $ 93,000. Following the deal, Imperial Oil shut down the Silver Star refinery in Petrolia and moved its refining operations to Sarnia, Ontario. In a landmark 1911 anti-trust case , the U.S. Supreme Court ordered Standard Oil to break up into 34 separate companies. Ownership of Imperial Oil, as well Standard Oil's other subsidiaries outside the U.S., were all transferred to only one of those 34 successor firms, Jersey Standard (later renamed Exxon ). Imperial Oil discovered
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
780-428: 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
858-430: 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

#1732877070687936-645: 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
1014-658: 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
1092-462: 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
1170-526: A separate subsidiary, independent of Imperial Oil. From the 1934-35 season through the 1975-76 season , Imperial Oil was a sponsor of the Canadian Broadcasting Corporation program Hockey Night in Canada for both radio and television broadcasts. Esso, which had three stars on their signs, sponsored Hockey Night in Canada 's three stars of the game. In the same era, the company

A number of refineries are located in Sherwood Park, Alberta , directly adjacent to
1326-482: A way to remove the sulphur content in the oil pumped at Lambton County . The high sulphur content in Canadian oil placed it at a disadvantage compared to the oil mined at Pennsylvania due to its "distinctive odour" when burned. Canadians called the product "skunk oil". Between 1885 and 1887, Frasch discovered that mixing copper oxide with the oil during the distilling process would remove the sulphur content and odour from

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)
2106-475: 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

The Ploiești refineries, after being taken over by Nazi Germany , were bombed in the 1943 Operation Tidal Wave by
3822-555: 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 ,

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
