Valero Energy Corp. reported above-normal emissions at its Corpus Christi, Texas refinery following an incident with a sulfur recovery unit.

"A loss of integrity was discovered on the outlet pipe of SRU Train 3 condenser," the refinery said in a statement to the Texas Commission on Environmental Quality.

Acid gas is being routed to standby trains to allow for repairs, Valero said.

It said the emissions of some 100 pounds of hydrogen sulfide began Thursday and were expected to last about nine hours.

Valero's 293,000-barrel-a-day Corpus Christi refinery includes an east and west plant. This incident happened at the west plant.
