An oil refinery or petroleum refinery is an industrial process plant where petroleum is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemical feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant. 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.
Petroleum Company of Trinidad and Tobago Limited was a state-owned oil company in Trinidad and Tobago. Its principal activities were the exploration, development and production of hydrocarbons in addition to the manufacturing and marketing of petroleum products.
Catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes, which are then partially dehydrogenated to produce high-octane aromatic hydrocarbons. The dehydrogenation also produces significant amounts of byproduct hydrogen gas, which is fed into other refinery processes such as hydrocracking. A side reaction is hydrogenolysis, which produces light hydrocarbons of lower value, such as methane, ethane, propane and butanes.
Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum into gasoline, alkene gases, and other petroleum products. The cracking of petroleum hydrocarbons was originally done by thermal cracking, now virtually replaced by catalytic cracking, which yields greater volumes of high octane rating gasoline; and produces by-product gases, with more carbon-carbon double bonds, that are of greater economic value than the gases produced by thermal cracking.
The Gujarat Refinery is an oil refinery located at Koyali, Vadodara District in Gujarat, Western India. It is the third largest refinery owned by Indian Oil Corporation after Paradip and Panipat Refinery. The refinery is currently under projected expansion to 18 million tonnes per year.
Kochi Refinery Limited (KRL) is a crude oil refinery in the city of Kochi in Kerala, India. It is the largest public sector refinery in India with a production capacity of 15.5 million tonnes per year. Formerly known as Cochin Refineries Limited and later renamed as Kochi Refineries Limited, it was acquired by Bharat Petroleum Corporation Limited in the year 2006. The refinery is situated at Ambalamugal, around 12 km (7.5 mi) east of the city centre.
The Nelson complexity index (NCI) is a measure to compare the secondary conversion capacity of a petroleum refinery with the primary distillation capacity. The index provides an easy metric for quantifying and ranking the complexity of various refineries and units. To calculate the index, it is necessary to use complexity factors, which compare the cost of upgrading units to the cost of crude distillation unit.
U.S. Oil & Refining Co. is an oil refinery located in the tideflats of Tacoma, Washington.
Fawley Refinery is an oil refinery located at Fawley, Hampshire, England. The refinery is owned by Esso Petroleum Company Limited, a subsidiary of Exxon Mobil Corporation, which acquired the site in 1925. Situated on Southampton Water, it was rebuilt and extended in 1951 and is now the largest oil refinery in the United Kingdom, and one of the most complex refineries in Europe. With a capacity of 270,000 barrels (43,000 m3) per day, Fawley provides 20 per cent of the UK's refinery capacity. Over 2,500 people are employed at the site.
The Płock refinery is a large oil refinery and petrochemical complex located in Płock, Poland. It is owned by PKN Orlen, and is one of the two crude oil refineries in Poland, the other one is Gdansk refinery. The refinery has a Nelson complexity index of 9.5 and a capacity is 16.3 million tonnes per year or 276,000 barrels per day of crude oil.
Gdańsk oil refinery is a 10.5 million tonne per year refinery located near the Polish city of Gdańsk on the Baltic Sea. The refinery was established in 1975 to supply fuels and lubricants, and has undergone several upgrades and expansions to increase its capacity and the range of products available. It now has a Nelson complexity index of 11.1. It is one of two oil refineries in Poland, the other is Plock refinery.
Corinth Refinery is an oil refining complex in Greece, the largest industrial complex in the country with a capacity of 380,000 barrels per day (60,000 m3/d), and it is operated by Motor Oil Hellas.
The BPRefinery (Kent) was an oil refinery on the Isle of Grain in Kent. It was commissioned in 1953 and had a maximum processing capacity of 11 million tonnes of crude oil per year. It was decommissioned in August 1982.
The Montreal East Refinery was an oil refinery located in Montreal East and formerly Shell Canada's largest refinery. In October 2010, refinery operations permanently ceased and the facility was subsequently converted into a storage terminal.
The Gulf Refinery at Milford Haven was an oil refinery situated on the Pembrokeshire coast in Wales. The refinery, originally owned and operated by Gulf Oil, was opened in August 1968 by Queen Elizabeth II. The plant, constructed at a cost of approximately £35 million, produced a range of petroleum products and occupied an area of 300 acres. It was initially designed to process 60,000 barrels of crude oil per day. The capacity was increased to 119,000 barrels (18,900 m3) a day of oil.
Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil with CAS-no 64742-48-9. It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline.
The Tema Oil Refinery (TOR) is one of two crude oil refineries in Ghana. In 1977, the Government of Ghana became the sole shareholder. The name of the refinery was changed to the Tema Oil Refinery in 1991. The refinery was first named the Ghanaian Italian Petroleum Company (GHAIP).
The Dangote Refinery is an oil refinery owned by Dangote Group that was inaugurated on the 22nd of May 2023 in Lekki, Nigeria. When in full operation, it is expected to have the capacity to process about 650,000 barrels per day of crude oil, making it the largest single-train refinery in the world. The investment is over 19 billion US dollars.
Barmer Refinery is an upcoming public sector refinery and petrochemical complex in the Pachpadra of Rajasthan, India. It is owned by HPCL Rajasthan Refinery Limited (HRRL), a joint venture between Hindustan Petroleum Corporation Limited and the Government of Rajasthan.
