Valero Says Valve Opened on Port Arthur Coking Unit
By Samantha Zee – Sep 20, 2010 5:32 PM CT Valero Energy Corp. reported a wet gas compressor valve opened on a delayed coking unit at its Port Arthur, Texas, refinery, leading to flaring, according to a filing with state regulators.
The valve was closed and the event is being investigated, according to the filing with the Texas Commission on Environmental Quality. Flaring associated with the malfunction began at 3:13 a.m. local time and lasted four minutes, the filing showed.
“It was a brief trip of the compressor but had no impact to refinery production,” said Bill Day, a company spokesman.
The plant, about 90 miles east of Houston, can process 287,000 barrels of crude a day, according to data compiled by Bloomberg.
