1. Initial precipitation of sulfate as gypsum 2. Precipitation of metals as hydroxides in a gypsum matrix 3. Additional sulfate removal via ettringite precipitation 4. pH reduction using recarbonation. Figure 1 shows the simplest version of the process where only final sulfate removal is required. Only Steps 3 and 4 of the CESR process are shown.

Production. Ammonium sulfate is made by treating ammonia, often as a byproduct from coke ovens, with sulfuric acid: 2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O). Finely divided gypsum is added to an ammonium carbonate solution.
The reactivity of flue gas desulphurization gypsum with ammonium carbonate has been studied in the temperature range (20–50) °C. Mechanism of this reaction was suggested and the kinetics parameters characterizing the reaction were determined. A mathematical model suitable for the prediction of the conversion of gypsum was proposed.
