ABSTRACT:
A process is provided in which particulates, nitrogen oxides, and sulfur oxides are simultaneously removed from flue gases in a granular bed filter and scrubber with a nitrogen oxide-capturing reducing agent and a bed of sulfur oxide-capturing and particulate-removing material. The spent sulfur oxide-capturing and particulate-removing material can be regenerated in a lift pipe riser.
