Ethylene (C2H4) is an olefinic hydrocarbon used as feedstock for various processes and production of petrochemicals, such as PE, SM, VCM, VAM, EG, etc.
Propylene (C3H6) is an olefinic hydrocarbon recovered from refinery processes or petrochemical processes. The propylene produced by Formosa Petrochemical's naphtha crackers is typically non-fuel use propylene. Non-fuel use propylene is one intended for use in non-fuel applications, such as petrochemical production and processes. Non-fuel use propylene includes chemical-grade propylene, polymer-grade propylene, and trace amounts of propane. Propylene is used as feedstock for various processes and production of petrochemicals, such as PP, AN, Phenol, 2EH, etc.
Butadiene, or 1, 3 butadiene, is a flammable gaseous olefin used in the production of synthetic elastomer (synthetic rubber), ABS, 1, 4-butanediol and nylon 6, 6.
Riffinate-1, or BBR, is a mixture of 1-butene, 2-butene, isobutene (isobutylene) and butane, used in the production of MTBE and 1-butene.
