Update on US refinery production outages

Listed below are unplanned and planned production outages at US refineries as reported by Dow Jones Newswires. The information is compiled from both official and unofficial refining sources and does not purport to be a comprehensive list.

Citgo Corp.'s Lake Charles, Louisiana refinery has experienced two upsets in as many days, according to two separate filings to the US National Response Center. On March 13, a compressor at the refinery's Coker One Unit began flaring a release of hydrogen sulfide, and on March 12 a leak at the B-Reformer Unit released an unknown quantity of distillate into the atmosphere. The cause of these events were not known. Citgo was not available to comment.

Valero Energy Corp. on March 13 said an early-day electrical upset at its Port Arthur, Texas refinery had no material impact to production. All units were in operation, the company spokesman said.

Phillips 66 on March 13 said maintenance at a key gasoline-making unit's wet gas compressor at its Borger, Texas refinery has concluded. The planned work started on Feb. 27.

Chevron Corp. on March 11 restarted a major electrical unit at its refinery in Richmond, California. The unspecified unit had been shut down to investigate the cause of the upset, a filing to local environmental regulators said.

Valero on March 11 said the new, 57,000 barrels-a-day hydrocracking unit at its Port Arthur, Texas, refinery was shut for compressor repairs. The same unit had returned to service on March 4 after a five-day unplanned shutdown. A second, 45,000 barrels-a-day hydrocracking unit is operating normally, a company spokesman said.

Valero on March 11 said a hydrogen plant upset at its Benicia, California refinery forced the shutdown of a hydrocracking unit on March 10. A restart timing is not yet available.

Phillips 66 on March 11 said power to its oil refinery in Sweeny, Texas has been fully restored and the plant is in the process of restarting after a third-party provided power failure on March 10. It will take several days for the refinery to reach normal operations, a Phillips 66 spokesman said.

A malfunction at BP-Husky Refining LLC's Toledo-area refinery in Oregon, Ohio had no impact on production, a person familiar with operations at the plant said on March 11. The refinery reported emissions due to a problem at the plant's tail-gas thermal oxidizer on March 10 to the US National Response Center.

Shell Oil Co. on March 9 reported flaring because of equipment failure at its joint venture Deer Park Refinery in Deer Park, Texas. The snag released emissions of acid gas to the plant's safety flare stack. No further information was provided in the report to local environmental regulators. Separately, Shell said a small fire on March 10 at the Deer Park Refinery was quickly extinguished. No further details were provided, and the impact to production was unclear.

PBF Energy Inc. on March 9 reported flaring owing to a release of sulfur dioxide at its Delaware City Refinery in Delaware. The unit(s) involved in the event wasn't specified in the company's report to local environmental regulators. Impact to production was unclear.
