FGD Gypsum Production Process Gypsum Association

To make FGD gypsum, the sludge is oxidized by forcing clean, compressed air through it. In the oxidation vessel, calcium sulfite sludge is converted to calcium sulfate (CaSO 4 ), which almost immediately combines with some of the water in the slurry to form calcium sulfate dihydrate (CaSO 4 ·2H 2 O).
