ABSTRACT:
Apparatus and method for cleaning dirty gases using an apparatus comprising a particulate bed through which the dirty gases pass upwardly without being fluidized while a wash liquid descends through the bed .Clean gas supplied to a small region below the bed passes through a channel within the bed. Bed particles, preferably hollow spheres of polypropylene, are entrained in the clean gas and are transported by it to the top of the particulate bed. By this transportation, clogging, dense packing of bed material, and channel formation within the bed, are avoided.
