Valero Has Leak, Emissions at Port Arthur Refinery

Valero Energy Corp. said a leaking depropanizer overhead trim cooler in a catalytic reforming unit led to emissions at its Port Arthur refinery in Texas, according to a filing with state regulators.

The leak was discovered at about 8:00 a.m. local time, according to a filing with the Texas Commission on Environmental Quality. The work is expected to end by Nov. 2.

“There was no impact to production associated with this emissions report,” said Bill Day, a company spokesman. “It was a leak in a depropanizer cooler in a reformer unit, and repairs are under way.”

The plant, about 90 miles east of Houston, can process 287,000 barrels of crude a day, according to data compiled by Bloomberg.
