Cokemaking

Granite City

Our Granite City cokemaking facility began operations in October 2009. It has 120 cokemaking ovens and produces 650,000 tons of coke per year. Substantially all of the coke produced at this facility is sold to U.S. Steel. The coke is delivered via conveyer belt directly to U.S. Steel’s nearby blast furnace facility. In addition, our Granite City facility generates over 500,000 pounds per hour of superheated steam from process waste heat, which is delivered to U.S. Steel’s adjacent cogeneration facility.

Haverhill

Our Haverhill cokemaking facility is located in Franklin Furnace, Ohio. The facility was built in two phases: the first was commissioned in 2005 and the second commenced operations in 2008. This plant now has 200 cokemaking ovens and produces 1.1 million tons of coke annually. Our Haverhill operations supply coke to ArcelorMittal and AK Steel, delivering product via rail and truck.

The initial phase of the Haverhill facility includes a process steam plant that generates low-pressure steam from the flue gas produced during the cokemaking process. This process steam is sold to an adjacent chemical manufacturing complex.

The second phase of the Haverhill facility includes a cogeneration plant that uses the hot flue gas produced during the cokemaking process to generate electricity. The plant generates approximately 45 megawatts of electrical power per hour, which is sold primarily to AK Steel.
