Since all of the slurry liquor is evaporated in spray dryerbased "dry" FGD systems, in these systems all of the absorbed mercury will be found in the solids stream. Additional technologies have been developed to enhance the percentage oxidation of mercury in flue gas at the FGD inlet, and to limit reemission of mercury in the absorber.
Aug 11, 2018· 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.
