Three Rivers Refinery
The Valero Three Rivers Refinery is located approximately 70 miles south of San Antonio, and in the heart of Eagle Ford Shale production. This economic advantage makes it an important link in Valero's operations in the Southwest. The plant, situated about halfway between San Antonio and Corpus Christi, Texas, began operations in 1974 with the commissioning of a crude unit and has had several major expansions and upgrades since then. The first expansion was in 1978 and 1979 when catalytic reformer and vacuum distillation units were added. In 1981, a fluidized catalytic cracking unit (FCC) and alkylation unit were added. In 1990 and 1992, the crude unit was expanded again. A continuous catalytic reformer was added in 1991. A hydrocracker unit was built in 1993, and a gas oil hydrotreater and hydrogen plant were moved to the plant site in 1995 and 1996. Additionally, a petrochemicals BTX extraction unit was added in 1996. Beginning in 2003, units were modified to provide the capability of processing medium-sour crude oil. The refinery is capable of producing a wide variety of products including gasoline, diesel fuel, jet fuel, benzene, toluene, xylene, liquefied petroleum gases (LPGs), propylene, No. 6 fuel oil, fuel gas and sulfur. Due to the proximity of the Eagle Ford Shale formation, the refinery receives mostly local crude by trucks and pipelines. The finished products are mainly shipped by pipeline to the San Antonio terminals. The refinery also produces naphthenic lubricants/specialty process oils.
