Additional Use of Coke Oven GasCosts & Benefits
|Parent Process: Coke Making|
|Energy Savings Potential||
Coke oven gas with a heating capacity of 6 to 8 GJ can be recovered for every ton of coke produced. (IEA, 2007)
In China, the potential of recovering COG from stand-alone coke enterprises was estimated to be around 250 PJ in 2005.
|CO2 Emission Reduction Potential||
In China, CO2 emissions can be reduced by 25 million tons by recovering COG from stand-alone coke enterprises located near coal mines
By using COG as supplementary fuel in blast furnace, a steel mill in the US was able to save US $6 million annually. The project required an investment of around US $6.1 million, and had a payback time of just over one year.

Additional Use of Coke Oven Gas Publications
The U.S. Environmental Protection Agency’s (EPA) energy guide, Energy Efficiency Improvement and Cost Saving Opportunities for the U.S. Iron and Steel Industry, discusses energy efficiency practices and technologies that can be implemented in iron and steel manufacturing plants. This guide provides current real world examples of iron and steel plants saving energy and reducing cost and carbon dioxide emissions.
Additional Use of Coke Oven Gas Case Studies
This case study provides an overview of how an integrated iron and steel mill in the US has started to use COG in blast furnace and therby saved around US $6 million/y.
