Dry scrubbing systems are used to remove acid gases (such as SO2 and HCl) primarily from combustion sources. Dry scrubbing systems consist of two main sections or devices: the scrubber and the scrubber media. Dry scrubbers spray very fine absorbents into a vessel where they combine with flue gases. The resulting sorbent is captured by the ...
