In coking project phase 1 for Baosteel,a process of Spray Dryer Absorber (SDA)+bag filter system+Selective Catalytic Reduction (SCR) is adopted for coke oven flue gas DeSOx and DeNOx,which was put into operation in October 2016; for phase 3 & 4,a process of active carbon Soda DeSOx (SDS)+medium & low temperature SCR,which were put into operation in November 2019.Operation of the two processes are compared in terms of operability,DeSOx and DeNOx efficiency,by-products treatment and operating cost.
