ExxonMobil Baton Rouge Refinery

Both Exxon and Mobil descended from Standard Oil which was established in 1870.  Standard Oil, also known as Esso, was split up into 34 companies in 1911.  The Baton Rouge refinery was constructed by one of the 34 companies, Standard Oil of New Jersey.  Meanwhile, Humble Oil and Refining Company was founded in Texas in 1911.  Over time, Humble Oil and Refining Company became affiliated with Standard Oil of New Jersey, and they eventually consolidated in 1959.  In the early 1970s, Standard Oil of New Jersey became Exxon Corporation, and Humble Oil became Exxon USA.  In 1998, Exxon and Mobil merged and became ExxonMobil.

The ExxonMobil Baton Rouge Refinery produces gasoline, diesel, jet fuel, aviation fuel, lubricating oils and waxes and has employed thousands of workers over the years.  Occupying 2,100 acres, it is considered the third largest refinery in the United States and currently employs approximately 2,500 workers.
