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.

Community Advisory Panel

Year established: 1992

The Sweeny Refinery Community Advisory Panel (CAP) serves as a forum in which the needs of the community and the refinery's role in the community are shared in a balanced and positive manner. CAP meetings provide an opportunity to discuss plant operations, community concerns or issues, and the current business climate. CAP members are a diverse group, including civic/academic leaders, government officials, business leaders and owners, retirees, and company management. Phillips 66 representatives on the CAP include the refinery manager, environmental, safety and security, emergency response and community relations personnel. Dedicated to generating open and honest communication between the community and the refinery, the CAP plays a vital role.

The Sweeny Refinery Community Advisory Panel is comprised of approximately 20 citizen members and 25 company members, with an average meeting attendance of 30.

Meetings are conducted bi-monthly, with facilities and lunch provided by the company.
