Title

Tesoro Reliability Improvement and Regulatory Compliance Project

Description

The purpose of the Tesoro Improvement and Regulatory Compliance Project is to improve the reliability of refinery operations and to comply with regulatory requirements. The proposed project includes the following changes to the Refinery: 1) install a new fuel gas treatment unit; 2) replace an existing cogeneration system with a new, more efficient cogeneration system; 3) replace multiple, existing stream boilers with new, more efficient equipment; 4) modify the Delayed Cooking Unit (DCU), the Hydrocracking Unit (HU), and the Fluid Catalytic Cracking Unit (FCCU) to increase recovery of liquefied petroleum gas (LPG); 5) modify the existing coke handli9ng, screening, and loading system; 6) modify existing Hydrotreating Unit (HTU) No. 2 in order to comply with the revised California Air Resources Board's gasoline specifications (revised CARB Phase III); 7) upgrade the existing amine/sour water system to improve hydrocarbon removal efficiency; 8) connect certain existing atmospheric pressure relief devices (PRDs) to the existing flares to prevent direct atmospheric releases; 9) recover and treat sour gas from the spent acid storage tank and the LPG sulfur extraction unit; 10) modify the coke drum blowdown system; 11) modify heater number H-101 at the DCU; and 12) install a new crude oil storage tank. The proposed project at the Sulfur Recovery Plant will modify an existing Claus Unit to improve sulfur recovery.
