The Joliet Refinery is also among the most energy-efficient refineries of its size in the country, and is striving to be on par with European standards for energy efficiency.
The refinery’s energy efficiency comes in part from two key technologies. Through cogeneration, energy produced in the course of refining is captured and converted into electricity, heat or steam to be used as power. Using heat integration, units at the refinery collect heat and recycle it back into the refining process to ensure smooth operations. Running an energy-efficient refinery results in lower operating costs and significantly reduced emissions.
