Conoco Said to Shut Sulfur Recovery Unit at Louisiana Refinery

ConocoPhillips has shut the main sulfur recovery unit at its Lake Charles refinery in Westlake, Louisiana, people familiar with the plant’s operations said.

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.
