Sunoco Reports Faulty Weld on Line at Marcus Hook

June 2 (Bloomberg) -- Sunoco Inc. reported a faulty weld on a process line associated with an alkylation unit at the Marcus Hook refinery in Pennsylvania, according to a Pennsylvania regulator.

The release was reported at about 4:30 p.m. local time yesterday, said Deborah Fries, a spokeswoman with the Pennsylvania Department of Environmental Regulation.

“Sunoco did not state that the unit was or was going to be shut down,” she said in an e-mail today.

Outages can increase prices for refined products as companies turn to spot markets to help them meet supply contracts. Operational disruptions can also depress prices for crude oil as less feedstock is used.

Thomas Golembeski, a company spokesman based at company headquarters in Philadelphia, declined to comment on daily refinery operations.

The plant can process 194,000 barrels of oil a day, according to data compiled by Bloomberg.
