Gypsum/ammonium sulfate slurry and ammonium carbonate solution were fed directly into the agitated premix tank. The slurry of FGD gypsum/ammonium sulfate/ammonium carbonate was metered to the converter. During the pilot plant tests the ammonium carbonate feed rate frequently exceeded 105% of the stoichiometric requirements.
