Petrochemical Synthesis

Petrochemicals are used to manufacture thousands of products people use every day. Air Liquide guarantees its customers a safe, reliable and competitive supply of gases required for their production processes so they can focus on their core business.

Petrochemical Synthesis at a Glance

Petrochemical synthesis is the process whereby petroleum hydrocarbons from either petroleum or other fossil fuels like gas and coal, as well as biomass, are converted into chemical products. Air Liquide has an extensive experience in supplying industrial gases that are vital for petrochemical synthesis. Many processes require the use of oxygen, hydrogen, carbon monoxide and nitrogen in large volumes. The resulting chemicals products are then used to make thousands of synthetic products, such as textiles, plastics, rubber, fibers, fertilizers, paints, building materials and medical products.

Those gases act as reactants in the chemical process. Nitrogen is sometimes used as a reactant but mainly for its inerting properties.

Beside the industrial gases, Air Liquide is also able to supply steam and power to its petrochemical customers, typically from cogeneration facilities.
