FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.

In the kiln system, the material and gas flow in opposite direction. During this process, 211.15 t/h of raw meal and 6.88 t/h of coal are fed to the pyro-processing unit, and only 150.90 t/h of calcined raw meal is transported to the kiln. Approximately 85% of the carbonate breaks down during this process in the surveyed plant.

Selection of Calcination Process. Limestone calcination process is selected on basis of limestone. If size of limestone is less than 4 inches and capacity of plant is less than 200 tonnes per day, then shaft kiln is selected. Whereas for higher capacities and for small stone size sludges (industrial waste), rotary kiln is installed.
