Propylene is a colorless, gaseous hydrocarbon. It is a petrochemical feedstock used primarily in the manufacture of plastics via polypropylene or cumene. It is also used to produce propylene oxide, acrylic acid, oxo alcohols and isopropanol. Marathon produces three grades of propylene at its refineries: refinery grade (RGP), chemical grade (CGP), and polymer grade (PGP), varying in purity from approximately 65% propylene to more than 99% propylene.
Production Information
Marathon generates saleable propylene from six of its seven refineries. Propylene is produced in the refinery cracking units that upgrade heavier feedstocks into light products, such as gasoline and distillate. Cokers also create a propylene by-product. See the specific locations, quantities, and grades produced at each refinery in the table below.
Transportation
Marathon transports propylene from the refineries via pipeline, rail, and truck. It must be stored and transported in pressurized containers to keep the product in a liquid state. Since all transportation modes are not available at all facilities, the table below illustrates MPC’s current logistical capabilities.
