Ultra Low Emission and Continuous Operation Technology for Desulfurization and Denitrification of Coke Oven Flue Gas
By analyzing different processes ofcoke oven flue gas desulfurization and denitrification sys-tems and comparing the operating characteristics of different devices,this paper introduces the system backup,system switching,and continuous operation schemes for ultra-low emissions of coke oven flue gas desulfurization and denitrification.On the premise of ensuring compliance with environmental protection indicators,a new system is put into use to replace the old processes with higher operating costs.The aux-iliary material cost per ton of coke is reduced by 6.7%,the annual gas consumption is saved by 2.4 million cubic meters,steam consumption is reduced by 12000 m3,and the hidden danger of exceeding the environ-mental protection index during shutdown maintenance and fault shutdownis eliminated.
