April 12, 2023 [MarketWatch] – Marathon Petroleum Corp. reported above-normal gas emissions Monday at a Sulfur Recovery Unit of its Galveston Bay refining complex near Houston.
“Sul[fur] trap plugged allowing H2S [hydrogen sulfide] directly to incinerator,” the refinery said in a statement to the Texas Commission on Environmental Quality. “Unit resolved the issue and returned to normal operations.”
It said the emissions began early Monday morning and ended shortly after noon, lasting about 12 hours in total.
Marathon’s 565,000 barrel-a-day Galveston Bay complex is the second-largest U.S. refinery after Saudi Aramco’s 603,000 barrel-a-day Motiva refinery in Port Arthur, Texas.
