An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful 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.
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 much of the technology and can be thought of, as types of chemical plants. Since December 2008, the world's largest oil refinery has been the Jamnagar Refinery owned by Reliance Industries, located in Gujarat, India, with a processing capacity of 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 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 Arab chemists, with clear descriptions given in Arabic handbooks such as those of Muhammad ibn Zakarīya Rāzi (865–925). The streets of Baghdad were paved with tar, derived from petroleum that became accessible from natural fields in the region.

alt=Flasque comprenant du pétrole brut|vignette|Pétrole brut Le pétrole (en latin , du grec petra, « roche », et du latin , « huile »), dit aussi naphte dans l'Antiquité, est une huile minérale d’origine naturelle composée d'une multitude de composés organiques, essentiellement des hydrocarbures, piégée dans des formations géologiques particulières. Le pétrole dans son gisement est fréquemment associé à des fractions légères qui se séparent spontanément du liquide à la pression atmosphérique, ainsi que diverses impuretés comme le dioxyde de carbone, le sulfure d'hydrogène, l'eau de formation et des traces métalliques.
Le craquage (cracking en anglais) est, en pétrochimie, la thermolyse du pétrole et de ses dérivés liquides. L'opération consiste à casser une molécule organique complexe en éléments plus petits, notamment des alcanes, des alcènes, des aldéhydes et des cétones. Les conditions de température et de pression, ainsi que la nature du catalyseur sont des éléments déterminants du craquage. En dehors de l'industrie pétrochimique, le craquage comprend toute dissociation induite d'une molécule (par exemple, le craquage de l'eau), à travers un processus tel que la thermolyse, la pyrolyse ou la photolyse.
Petrochemicals (sometimes abbreviated as petchems) are the chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as maize, palm fruit or sugar cane. The two most common petrochemical classes are olefins (including ethylene and propylene) and aromatics (including benzene, toluene and xylene isomers). Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions.
