ABSTRACT:
A scrubber module (16) of the wet type includes a partition (26) extending across the upper end of a tank (20) between the dirty flue gas inlet (28) and the clean flue gas outlet (30). The partition (26) takes the form of a plurality of hollow fingers (32), the zig-zag lower edge of which is submerged in the aqueous absorbent (22). Oxygen-containing gas such as air is introduced into the lower end of the tank (20) as the flue gas is forced underneath the partition (26) at the upper end of the tank without pre-cleaning of the flue gas to facilitate wetting and capture of the fly ash particulate as well as oxidation and absorption of the sulfur dioxide into calcium sulfate in solution, in the same vessel.
