Making Limestone Slurry for FGD. The process can be supplied as a single pass steady state process by measuring the finished slurry density discharging from the mixer. The water delivery rate to the mixer can be adjusted by ± 15% to maintain targeted solids levels. The unit conveys conditioned limestone powder from a surge hopper . More
Limestone slurry is prepared mixing fine limestone powder with water in a slurry preparation tank. Sorbent slurry from this tank is then pumped into the absorber reaction tank. The absorber is a counterflow tower with flue gas flowing upwards, while limestone slurry is sprayed downwards by an array of spray nozzles.
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 ...
