Fire at Exxon Mobil’s Baytown complex

Exxon Mobil’s emergency teams on Wednesday evening battled a fire at  its Baytown complex, which includes one of the largest refineries in the world.

The fire broke out about 5 p.m. and was confined to a process unit, Exxon Mobil spokeswoman Rachael Moore said in an email.  No injuries were reported and all employees were accounted for, she said.

The flames were extinguished at approximately 8:30 p.m., a company statement said. A crew remained on the site late Wednesday.

Remaining plant operations were not impacted from the fire, the statement said.

Exxon Mobil’s Baytown complex houses both refining and chemical plants and has a staff of 2,200 company employees and 2,100 contractors that keep it running 24 hours a day, according to the company website.

It is capable of refining 573,000 barrels per day of crude oil, making it one of the largest refineries in the world. The refinery processes crude from the Persian Gulf, Africa, South America and Mexico. The Baytown refinery was the nation’s largest refinery by capacity in 2011, according to the U.S. Energy Information Administration.

It was not immediately clear what started the fire.

“As a precaution, our Industrial Hygiene staff is doing air quality monitoring around the complex and in the community,” Moore said. “We apologize for any inconvenience.”

More than 7.2 billion pounds of petrochemical products are manufactured each year at the complex, according to Exxon Mobil’s website.
