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.
Valero Energy Corporation is an American-based fuels producer mostly involved in manufacturing and marketing transportation fuels and other related products. It is headquartered in San Antonio, Texas, United States.

Catalytic reforming is a chemical process used to convert naphthas from crude oil into 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.
EP Petroecuador is the national oil company of Ecuador. Ecuador is a member of the Organization of the Petroleum Exporting Countries (OPEC) and, although it is the smallest member, the country produced 531,000 barrels of crude oil per day in 2019. The oil corporation is a significant part of the Ecuadorian economy. The petroleum industry has expanded to the production of refined commodities such as gasoline, liquefied petroleum, and jet fuel. The government of Ecuador is highly dependent on the revenues from the energy sector to support its budget and finance state projects.
Milford Haven Waterway is a natural harbour in Pembrokeshire, Wales. It is a ria or drowned valley which was flooded at the end of the last ice age. The Daugleddau estuary winds west to the sea. As one of the deepest natural harbours in the world, it is a busy shipping channel, trafficked by ferries from Pembroke Dock to Ireland, oil tankers and pleasure craft. Admiral Horatio Nelson, visiting the haven with the Hamiltons, described it as the next best natural harbour to Trincomalee in Ceylon and "the finest port in Christendom". Much of the coastline of the Waterway is designated as a Site of Special Scientific Interest, listed as Milford Haven Waterway SSSI.
The Llandarcy Oil Refinery, also known as the National Oil Refinery, BP Llandarcy and Skewen refinery, was the United Kingdom's first oil refinery, initially opened by the Anglo-Persian Oil Company on 29 June 1922, although operations had begun on 1 July 1921. Before this, the only oil refined in the UK came from Scottish shale.
Rhoscrowther was a village, ecclesiastical parish and civil parish in Pembrokeshire, Wales on the south shore of the Milford Haven Waterway. The placename is Welsh and perhaps means "crwth-player's moor". It is part of the community of Angle.
Coryton Refinery was an oil refinery in Essex, England, on the estuary of the River Thames 28 miles (45 km) from central London, between Shell Haven Creek and Hole Haven Creek, which separates Canvey Island from the mainland.
Shell Haven was a port on the north bank of the Thames Estuary at the eastern end of Thurrock, Essex, England and then an oil refinery. The refinery closed in 1999 and the site was purchased by DP World who received planning consent in May 2007 for the new London Gateway deep water container port at the site. The neighbouring Coryton Refinery remained in operation until 2012.
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.

It was Britain's third largest oil spillage and the twelfth largest in the world at the time.
