SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime ...
