Industrial Application and Improvement of Desulfurization and Denitrification Technology for Coke Oven Flue Gas
In order to solve the problem of environmental pollution and resource waste caused by direct discharge of coke oven flue gas,based on the analysis of coke oven flue gas composition and the principle analysis of process design,the optimal denitration and desulfurization process route was determined according to on-site production conditions.A desulfurization and denitrification process route model was constructed based on Aspen Plus software,and simulation analysis was conducted on the flue gas flow rate,reducing agent ammonia gas,liquid gas ratio,and calcium sulfur ratio for desulfurization and denitrification efficiency.Finally,the optimal denitrification and desulfurization process parameters were obtained.
