Marathon's Detroit, Michigan refinery is located near I-75 in southwest Detroit, Michigan, on approximately 200 acres. The refinery has the capacity to convert 102,000 barrels per day of crude oil into such products as gasoline, diesel fuel, asphalt, propane, kerosene, jet fuel, chemical grade propylene, sulfur, roofing flux and heating oil.


The Detroit refinery is the only refinery in the state of Michigan, and it is currently in the midst of a $2.2 billion heavy oil upgrade project that will increase crude capacity to 115,000 barrels per day and enable the processing of additional heavy crude oils when it is completed in mid-2012.


The refinery was first awarded the ENERGY STAR in 2007.


In 2002, the Detroit 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. In addition to a 2005 expansion that involved the installation of more energy efficient equipment, the Detroit refinery has focused on reducing consumption through improved operating and maintenance practices.  These include such practices as steam trap monitoring and repair programs, insulation studies and repairs, proper electric motor versus steam turbine operation, heater excess oxygen optimization and heat exchanger monitoring and cleaning. Savings from these practices account for annual energy reductions of 300,000 MMBTU per year.
