ABSTRACT:
A process for removing the sulfur oxides from a gas stream by sorbing the sulfur oxide gases in a zeolite and subsequently purging the previously-sorbed sulfur oxide gases by exposing the zeolite to water or water vapor, which is preferentially sorbed on the zeolite. The zeolite is then regenerated by desorbing the water or water vapor from the zeolite. A gas stream having a reduced volume and an increased sulfur oxide gas concentration is isolated and directed to sulfur oxide removal and processing apparatuses.
