GEA Bischoff - Dry Desulphurization

For the removal of SO2 from industrial waste gases GEA Bischoff has available several different processes: Dry desulphurization by lime injection in the gas flow upstream bagfilters; Dry desulphurization in the circulized fluidized bed (CFB); Semi dry desulphurization by injection of lime milk in a spray absorber (SDA); Wet desulphurization in counter current scrubber with limestone (CaCO3) or lime (Ca(OH)2) as absorbent; Wet desulphurization in counter current absorber with caustic soda as absorbent. This process can be combined with a WESP on top of the scrubber.
