Site

Located in Westlake, Louisiana, the Lake Charles Refinery processes primarily heavy, high-sulfur and high-acid crude oils, along with some light, sweet crude oil. It receives domestic Gulf Coast, U.S.-advantaged and foreign crude oils. Within the facilities are crude distillation, a fluid catalytic cracker, alkylation, a delayed coker and hydrodesulfurization units that enable the refinery to produce gasoline and diesel fuels, and fuel-grade petroleum coke. The facilities also include a specialty coker and calciner, which produce graphite petroleum coke for the steel industry.
