Flue Gas Desulfurization by Limestone and Hydrated Lime ...

Flue gas desulfurization (FGD) processes are usually categorized as wet and dry or semi-dry systems. In wet FGD processes flue gas is contacted with a slurry consisting of a sorbent in an aqueous medium, such that the flue gas is cooled to the adiabatic saturation temperature. Whereas, dry and semi-dry FGD processes involve injection of a
