The unit was shut yesterday after a leak was discovered, said the people, who declined to be identified because they aren’t authorized to speak for the refinery.
The refinery shut a unit because hydrogen sulfide was leaking from piping, according to a filing with the National Response Center. The filing didn’t identify the unit.
Bill Stephens, a company spokesman, didn’t immediately respond to an e-mail seeking more information.
Sulfur recovery units capture and hold sulfur removed during desulfurization.
The refinery processes mostly heavy, high-sulfur crude oil. Its main products are transportation fuels such as gasoline and jet fuel, according to the company’s website.
The plant, near Lake Charles in southwestern Louisiana, has a capacity of 252,400 barrels of oil a day, according to the Energy Department.
