Tesoro Carson Refinery Hydrotreater Seen Restarting Next WeekLynn Doan
Tesoro Corp.’s Carson plant, part of California’s largest refining complex, is expected to keep a hydrotreater shut until next week as it resolves a compressor malfunction, a person familiar with operations said.
The hydrotreater, which removes impurities from feedstock for the fluid catalytic cracker, was one of several units shut for planned work that began earlier this month, said the person, who asked not to be identified because the information isn’t public. Maintenance on the unit, initially expected to be finished by Nov. 28, was extended because of the compressor work, the person said.
Tina Barbee, a spokeswoman at Tesoro’s headquarters in San Antonio, declined by e-mail to comment. She said earlier today that the refinery is performing “planned maintenance activities.”
Tesoro bought the 266,000-barrel-a-day Carson plant from BP Plc in June and has been integrating the site with its 97,000-barrel-a-day Wilmington refinery. The Carson section includes the biggest fluid catalytic cracker in California, two cokers and distillate hydrocracking, according to a June 3 statement from BP.
A reformer, which processes desulfurized feedstock into high-octane gasoline blending components, is expected to return to service at Carson today or tomorrow after maintenance, said the person familiar with operations. Other equipment that was shut for the turnaround, including a sulfur unit, has been restarted, the person said.
The Carson section runs crudes from Alaska’s North Slope, the Middle East and West Africa, according to BP.
