Sweeny Refinery

Our Sweeny Refinery, in Old Ocean, Texas, 65 miles southwest of Houston, processes mainly heavy, high-sulfur crude oil as well as some light, low-sulfur crude oil. Sweeny receives U.S.- advantaged and foreign crude oil primarily through wholly and jointly owned terminals on the Gulf Coast, including a deepwater terminal at Freeport, Texas.

The refinery facilities include two fluid catalytic cracking units, delayed coking, alkylation, a naphtha reformer and hydrodesulfurization units. It operates nearby terminals and storage facilities in Freeport, Jones Creek and on the San Bernard River, along with pipelines that connect these facilities to the refinery.

The refinery produces a high percentage of gasoline, diesel and aviation fuels. Other products include petrochemical feedstocks, home heating oil and fuel-grade petroleum coke. Refined products are distributed throughout the Midwest and southeastern United States by pipeline, barge and railcar.
