About the Texas City Refinery

The Valero Texas City Refinery is located on the Texas City Ship Channel, approximately 40 miles southeast of Houston. With several recent upgrading projects, the refinery provides significant feedstock flexibility and product diversity to Valero's Gulf Coast operations. The plant dates to 1908, originally built to process 1,500 barrels per day of Oklahoma crude oil. The refinery has gone through continuous upgrades and expansions since then, including major upgrades from 1955 to 1970 when the total throughput of the refinery was increased from 40,000 to 130,000 barrels per day. In 1996, gas oil hydrotreater and residual oil solvent extraction units were commissioned along with significant revamps to the fluid catalytic cracking unit and the No. 3 crude unit. Since acquiring the refinery in 1997, Valero has invested more than $750 million in expansions and upgrades at Texas City. Most recently, the plant completed a major expansion consisting of a new delayed coker and a gasoline desulfurization unit. These expansions and upgrades give the facility a great deal of feedstock flexibility, resulting in a higher gross margin than a conventional refinery. The new units allow the crude units to run lower-value, heavier-gravity crude feedstocks to produce a large slate of low-sulfur, clean fuels.

Valero is an EEO/AA Employer. All qualified applicants are encouraged to apply and will receive consideration for employment without regard to legally protected status including sexual orientation, gender identity, Women, Minorities, Individuals with Disabilities and protected Veterans.
