The El Paso refinery is located approximately three miles east of downtown El Paso, Texas and is located on approximately 555 acres. The refinery was originally two facilities but the operations of the two plants were combined in 1993 and continue to operate as one entity today.

The “North” refinery was originally built by Standard Oil Company (later Chevron) in 1928 and was significantly modernized in 1957. It was subsequently modernized again in 1972 with the addition of a naphtha hydrotreater, catalytic reformer, and sulfur plant.

The “South” refinery was originally built by the Texas Company (later Texaco) in 1931 and was significantly modernized in 1954. The facility was subsequently sold in 1986 to El Paso Refinery, L.P. (EPR) and was again significantly modernized and expanded to more than three times its previous operating capacity between 1986 and 1991. The refinery has added a diesel hydrotreater, gasoline hydrotreater, and numerous additional units during the last few years providing added flexibility in processing lesser grades of crude.

The refinery has crude capacity of approximately 128,000 barrels per day, FCCU capacity of 29,500 barrels per day, alkylation capacity of 10,000 barrels per day and reforming capacity of 18,000 barrels per day.
