Flue gas desulfurization (FGD) technology has been adopted by a number of power stations for the removal of sulfur dioxide (SO2) from flue gas. ... with water in a slurry preparation .
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. In the absorber, SO2 is ...
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.
