ABSTRACT:
Apparatus and method for scrubbing gases such as flue gases by subjecting the gases to a shower of gas scrubbing solid particulate material. The scrubbing is desirably effected in a downwardly extending passage leading from the top of a stack from which flue gases are diverted into the top of the passage. The aggregate mass of the solid particulate scrubbing material shower may be great enough to cause down draft for improved stack draft. The particulate material is reconditioned after separation from the cleansed gas and reused in the gas scrubbing cycle. Reconditioning of the particulate material in a liquid also effects wetting of the material for improved scrubbing action. The liquid of the particulate material reconditioning bath may be filtered or otherwise reconditioned and recycled. The recycled material may agitate the spent gas scrubbing solid particulate material for improved reconditioning of the material.
