(Petrochemicals are a very complex industrial sector that influenced almost every sphere of life. In everyday life, use of plastics, soaps confirms the importance of petrochemicals in our daily world. The petrochemical industry links downstream sectors like pharmaceuticals with the upstream oil and gas industries. The petrochemical industry renovates feed stocks such as naphtha and natural gas components like ethane, propane and butane through steam cracking or catalytic cracking into petrochemical building blocks i.e. olefins and aromatics.

Petrochemicals are chemical derivatives from petroleum. Several chemicals made from petroleum are also acquire from other fossil fuels like coal or natural gas, or renewable sources like corn or sugar cane. Two major petrochemical classes are olefins (include ethylene and propylene) and aromatics (i.e. benzene, toluene and xylene isomers). Oil refineries manufacture olefins and aromatics through fluid catalytic cracking of petroleum fractions.

Main application of petrochemical is their exploitation as a fuel. The combustion of crude oil gave in-road to origin of numerous energies from petroleum. Petroleum has been a source of energy for lighting, heating and locomotion and predominantly the most expedient fuel for the internal combustion engine.

In addition to that, Petrochemicals are playing very significant role in various other industrial area. Industrial raw materials obtained or synthesized from petrochemicals are wax, fertilizers, preservatives, soaps and detergents, dyes, plastic commodities, plasters, sports shoes and explosives: most of the explosives contain petroleum products. In spite of an immense degree of progress and advancement, petrochemicals are still a key concern to global industrial sector. Present article covers the major industrial applications areas of petrochemicals.

Detergents have been synthesized using oils, alcohol (a petrochemical Products made from petrochemicals include such items as plastics, soaps and detergents, solvents, drugs, fertilizers, pesticides, explosives, synthetic fibers and rubbers, paints, epoxy resins, and flooring and insulating materials.
