| abstract |
A process is provided in which particulates, nitrogen noxides, and sulfur oxides are simultaneously removed from nflue gases in a granular bed filter and scrubber with a nnitrogen oxide-capturing reducing agent and a bed of sulfur noxide-capturing and particulate-re-moving material. The nspent sulfur oxide-capturing and particulate-removing matenrial can be regenerated in pipe riser by reaction with a nregenerating reducing agent. |
