The refinery currently has an alkylation unit shut for repairs, said the people, who asked not to be identified because the information is not public.
Hydrocrackers convert heavy feedstocks into lighter fuels such as high-octane gasoline and diesel. Alkylation units work with catalytic crackers to make high-octane gasoline blending components.
Todd Spitler, a spokesman for Exxon in Fairfax, Virginia, and Jennifer Hughes and Stephanie Cargile, spokeswomen for the refinery in Baton Rouge, didn’t immediately respond to requests for comment.
The Baton Rouge refinery can process 503,500 barrels of crude oil a day, according to data compiled Bloomberg.
