Research on treatment technology of CO in commonly used discharged flue gas of CDQ plant
The commonly used discharged flue gas of coke dry quenching(CDQ)has high CO content,and direct emissions will have certain impact on the environment.The CDQ process was introduced,and CO source and content in commonly used discharged flue gas of CDQ were analyzed.Combined with various CO treatment technologies,based on the overall consideration of commonly used discharged flue gas desulfurization technology of CDQ,the feasible route of CO treatment was analyzed.Through the 168 h experimental study using low-temperature catalytic combustion process in Qian'an Zhonghua Coal Chemical Co.,Ltd.,the results showed that the removal rate of CO could reach more than 98%,which could meet the emission requirements and make a certain contribution to energy saving and carbon reduction.
