BP Plc said the ultracracker at its Texas City, Texas, refinery had a leaking exchanger to the cooling tower that led to emissions, according to a filing with state regulators.
The issue resulted in hydrogen sulfide being released into the atmosphere, according to the filing with the Texas Commission of Environmental Quality.
Plant operators are developing a plan to reduce the load and isolate the exchanger to stop the leak, which was discovered about 4 p.m. local time yesterday, the filing showed. Scott Dean, a spokesman for BP, didn’t immediately return an e-mail seeking comment.
The refinery has a capacity of 475,000 barrels a day, according to data compiled by Bloomberg.
