Petroleum & Refinery
Statistics and facts on petroleum and refinery
Oil refining is the process by which crude oil is manufactured into more complex and useful products. This process comes mainly through purification, distillation and conversion of crude oil in refineries. Oil refineries are large industrial complexes, noticeable mainly by their tank farms, pipeline systems and flare systems. The best known refinery products are petroleum naphtha, diesel fuel, gasoline, kerosene, heating oil, LPG (liquefied petroleum gas) and asphalt base.
Refinery products can have gaseous, fluid and solid forms. On average, around one quarter of a modern oil refinery’s production is gasoline, while one fifth is diesel fuel and light heating oil. Approximately one tenth make naphtha (crude gasoline) and heavy heating oil, respectively. However, this depends on the types of crude oil as well as on the production methods of the plant.
Refined oil products play a major role in modern life. Gasoline and diesel are inevitable for the whole automotive market, while kerosene/jet fuel is needed in aeronautics. Naturally, the petrochemical industry is highly dependent on petroleum and some natural gas products. This is why petrochemical plants are often located near oil and gas refineries. Interestingly, many active substances in medicines are derived from refined crude oil products, mostly from naphtha.
