Oil Refinery or Petroleum Refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum Naphtha, Gasoline, Diesel Fuel, Asphalt Base, Heating Oil, Kerosene, Liquefied Petroleum Gas, Jet Fuel and Fuel Oils. Petrochemicals feed stock 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.

Processing units used in refineries

Petrochemicals (also known as petroleum distillates) are chemical products derived from petroleum. The two most common petrochemical classes are olefins (including ethylene and propylene) and aromatics (including benzene, toluene and xylene isomers).
