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 ...
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.
fgd slurry preparation powder bondhumal A typical lime/limestone Flue Gas Desulfurization (FGD) system consists of three major sub systems The reagent (lime or limestone slurry) preparation; The scrubber/SO2 absorber and mist eliminator, and slurry.
Abstract. The wetfluegas desulfurization (FGD) process plays an important role in removing watersoluble fluegas components such as sulphur dioxide (SO 2) and oxidized mercury the reducing environment of the FGD, there is the possibility of reemission of the already absorbed mercury (Hg) to the gas phase, which may be diminished by the utilization of specific additives.
