Wet Flue Gas Desulfurization with Lime/Limestone Slurry

Flow optimisation is therefore extremely necessary. In the mist eliminator, the drops carried from the absorption zone by the flue gas are returned to the process. At the outlet of the absorber, the clean gas is saturated and can be directly removed via a cooling tower or wet stack. Optionally the clean gas can be heated and routed to a dry stack.
