  • Our propylene facilities and related operations consist of seven propylene fractionation plants, a PDH unit, pipeline systems aggregating approximately 985 miles in length, and related petrochemical marketing activities. This business includes an export facility and associated above-ground polymer grade propylene storage spheres located in Seabrook, Texas.

    In general, propylene fractionation plants separate refinery grade propylene (a mixture of propane and propylene) into either polymer grade or chemical grade propylene along with by-products of propane and mixed butane. Polymer grade and chemical grade propylene can also be produced as a by-product of ethylene production. The demand for polymer grade propylene primarily relates to the manufacture of polypropylene, which has a variety of end uses, including film packaging, fiber for carpets and upholstery and molded plastic parts for appliance, automotive, house ware and medical products. Chemical grade propylene is a basic petrochemical used in the manufacturing of plastics, synthetic fibers and foams.
