CGS Wet Flue Gas Desulfurization (FGD) Systems
For a lime FGD system, a lime slaker processing pebble lime is required in place of the limestone wet ball mill. To facilitate the disposal of the solid waste, or to produce a saleable product in the form of high quality gypsum, a forced oxidation system may be utilized to oxidize the main reaction product, calcium sulfite, to gypsum.

Gypsum Calcination
Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.
