About Baytown

With a population of more than 77,000, Baytown, Texas, is located in the Gulf Coast region of the United States, just east of Houston, the nation's fourth largest city. Those who live and work in Baytown will find an area rich in history, as well as opportunities for outdoor activities due to its proximity to scenic waterways, namely Galveston Bay, the San Jacinto River and Buffalo Bayou.

Founded in 1919, ExxonMobil's Baytown Complex is located on approximately 3,400 acres along the Houston Ship Channel, about 25 miles east of Houston. Employing a workforce of more than 8,500, it is comprised of four manufacturing sites, including one in nearby Mont Belvieu, and a global technology center. These include the Baytown Refinery, one of the largest refineries in the United States, and the Baytown Olefins Plant, one of the largest ethylene plants in the world.

Its scope of products includes fuels, lube oils, and chemical compounds used in a diverse range of products, from auto battery cases, diapers and tire inner tubes to pharmaceutical uses, food packaging, trash bags and more.

The Baytown area sites are highly integrated, which makes the plants and products more efficient as we develop technologies to make cleaner fuels and work together to operate more safely and reliably.
