ExxonMobil Baytown Refinery Reports FCCU Emissions Event

DAVENPORT, FL (DTN) – Exxon Mobil Corporation reported an emissions event at its 588,000 bpd Baytown Refinery in Baytown, according to a filing with the Texas Commission on Environmental Quality.

The event began Sunday (5/11) at 12:45 p.m. and is expected to continue through Wednesday (5/13) at 12:45 a.m. CT, for a total duration of about 72 hours.

According to the filing, a leak on the inlet duct of Reactor 501A at Fluidized Catalytic Cracking Unit 3 resulted in sulfur dioxide emissions to the atmosphere. ExxonMobil estimated sulfur dioxide emissions at 500 pounds.

The company said refinery personnel are following unit procedures to isolate the leak and that fenceline monitoring conducted as a precaution indicated no adverse environmental impact to the refinery or surrounding community. ExxonMobil also said it expects to meet contractual commitments.

The Baytown refinery is the fifth-largest refinery in the United States and primarily produces gasoline, diesel, and jet fuel.

DTN reached out to ExxonMobil for additional details but did not get an immediate response.
