Baton Rouge Refinery

ExxonMobil's Baton Rouge Refinery in Baton Rouge, Louisiana is the sixth-largest oil refinery in the United States and seventeenth-largest in the world, with an input capacity of 540,000 oilbbl per day as of January 1, 2020. The refinery is the site of the first commercial fluid catalytic cracking plant that began processing at the refinery on May 25, 1942.

Standard Oil first erected the refinery in 1909. Today's facility is part of a complex made of nine individual plants across the region. The main plant is located on the east bank of the Mississippi River. There are about 6,300 workers spread across these sites, including 4,000 direct employees (the rest are contractors).

In 2013 Genesis Energy LP announced an investment of $125 million to improve ExxonMobil's existing assets in the Baton Rouge area. The investment includes plans to build an 18 mi, 20 in diameter crude oil pipeline that connects Genesis Energy's Port Hudson terminal, to ExxonMobil's Baton Rouge refinery.
