Petrochemicals Reference Gas Mixture
Petrochemical Gas Mixture (also known as petroleum distillates) are the chemical products obtained from petroleum by refining. Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions. Chemical plants produce olefins by steam cracking of natural gas liquids like ethane and propane.
Few examples of Natural Gas Standard are given below
