Wet Scrubber Systems - Lenntech

In wet scrubber systems an alkali sorbent solution (limestone or lime) is injected into the flue gas. The sorbent slurry is injected by using a spray tower. The CaCO3 slurry is sprayed from the top to the bottom and the hot flue gas flows from the bottom to the top of the SO 2 absorber (countercurrent flow system). The alkaline slurry reacts with the SO 2 into calcium sulfite, further ...
