Rotamass Flue Gas Desulfurization | Yokogawa America

SO 2 is an acid gas and the typical sorbents used to remove the SO 2 from the flue gases are alkaline. Lime slurry is sprayed directly into the stack gas and absorbs SO 2. When wet scrubbing with a Ca(OH) 2 (lime) slurry, the reaction produces CaSO 3 (calcium sulfite). Ca(OH) 2 (solid) + SO 2 (gas) → CaSO 3 (solid) + H 2 O (liquid)
