An apparatus for the removal of particulate matter and sulfur oxides from waste gases is disclosed. The apparatus comprises a vessel for cross-current contacting of the waste gas with a moving bed of acceptor for sulfur oxides, and separate processing chambers for removal of the particulate matter from the loaded acceptor, for the removal of sulfur oxides for the loaded acceptor, and for reactivating the acceptor.

Removal of sulfur oxides and particulate matter from waste gas streams

A process for the removal of particulate matter and sulfur oxides from waste gases is disclosed which comprises cross-current contacting of the waste gas stream with a moving bed of supported, copper-containing acceptor in a first zone, thereby accepting the sulfur oxides and filtering out the particulate matter, removing in subsequent separate zones the particulate matter and the sulfur oxides from the acceptor and, optionally, reactivating the acceptor in a subsequent zone before introducing it back into the first zone for further removal of sulfur oxides and particulate matter. An apparatus suitable for carrying out the process is also described.
