Petrochemicals (also known as petroleum distillates) are chemical products derived from petroleum. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as corn or sugar cane.Oil refineries produce ole fins and aromatics by fluid catalytic cracking of petroleum fractions. Chemical plants produce ole fins by steam cracking of natural gas liquids like ethane and propane. Aromatics are produced by catalytic reforming of naphtha. Ole fins and aromatics are the building-blocks for a wide range of materials such as solvents, detergents, and adhesives.
