Fugitive and Stationary Source Emissions from Coke Plants and Impact on the Local Ambient Air Quality

The steel industry is the leading producer and consumer of coke. It controls about 72% of world coke making capacity, the remaining 28% being controlled by independent producers most of whom use non-recovery coke ovens. In the UK, by-product recovery coke ovens are used in the integrated steel plants operated by Corus UK to provide for the needs of blast furnaces, the latter consuming approximately 85% of the coke production. By-product recovery coke ovens produce waste gases containing organic micro-pollutants including volatile and semi-volatile organic compounds (VOCs and SVOCs) such as benzene and polycyclic aromatic hydrocarbons (PAHs), respectively.
