Marathon's Texas City, Texas, refinery is located on Galveston Bay, off the entrance to the Houston Ship Channel. It was built in 1931 and acquired by Marathon (then The Ohio Oil Company) in 1962 from Plymouth Oil Company.


With a crude refining capacity of 76,000 barrels per day, the refinery processes mainly sweet crude oil. Its products include gasoline, diesel fuel, naphtha, light cycle oil, propane, propylene, benzene, toluene, xylene, sulfur and various other chemicals.


Texas City was first awarded the ENERGY STAR in 2006. 


In 2002, the Texas City refinery began developing a more comprehensive energy conservation program in conjunction with Marathon's corporate commitment to improve energy efficiency by 10 percent in 10 years.  This was accomplished through heat integration to eliminate some reboilers, replacement of condensing turbines for more efficient electric motors and fuel use optimization to minimize natural gas purchases.  A major redesign of the catalytic cracking unit in Texas City provided an opportunity for more efficient energy design.  Since the redesign in 2003, Texas City has saved over 1,400,000 MMBTU per year versus the earlier operations.
