USGS Fact Sheet 07601: Coal Combustion Products
As the flue gas comes in contact with the slurry of calcium salts, sulfur dioxide (SO 2) reacts with the calcium to form hydrous calcium sulfate (CaSO 4 2H 2 O, gypsum). Figure 2. Flow diagram of the fluegasdesulfurization process based on lime ( CaO ) or limestone ( CaCO 3 ), which are the sorbents used by 90 percent of FGD systems in the United States.

At conditions typical of flue gas desulfurization processes calcium sulfite dissolution was controlled by mass transfer, not surface reaction kinetics. Dissolution was fast at low pH and slowed near the equilibrium pH determined by dissolved Ca ++ and SO 3 = concentrations in the aqueous solutions, K sp of the CaSO 3 · 1/2H 2 O solids, and temperature.
