Abstract:

Analysis is made for the behaviors of coke oven waste gas from 6m battery fired with COG.Introduction is also given for the process in sequence of SCR DeNOx under low temperature,waste heat recovery and a new DeSOx by catalytic method, which can solve the problems of inactive catalyst due to blockage as well as off-line regeneration and maintenance, and therefore realize ultra-low emission in manner of stability and high efficiency and a comprehensive utilization of the waste heat and diluted sulphuric acid.
