Document Description
The Tesoro Reliability Improvement and Regulatory Compliance Project will occur at Tesoro's Refinery and at their separate Sulfur Recovery Plant. The purpose of the proposed project is to increase the reliability of specific existing processing equipment at both Tesoro facilities. The proposed changes to the Refinery include the following: (1) install a new fuel gas treatment unit; (2) replace an existing cogeneration system with a new cogeneration system; (3) replace multiple, existing steam boilers with new equipment; (4) modify the Delayed Coking Unit (DCU), the Hydrocracking Unit (HCU) and the Fluid Catalytic Cracking Unit (FCCU) to increase recovery of liquefied petroleum gas (LPG); (5) modify the existing coke handling, screening, and loading system; (6) modify the 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 to the existing flares to prevent direct atmospheric releases; (9) improve sulfur treatment for the 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. The purpose of these modifications is to increase the reliability of specific existing Refinery processing equipment.
