granular gypsum flue gas desulfurisasi ammonium sulfat
FGD gypsum is formed when fossil-fueled power plants utilize flue gas desulfurization systems to remove sulfur dioxide from gas pollutants. Using a process referred to as scrubbing, gas pollutants are fed through calcium carbonate to eliminate impurities and environmental concerns.
