Abstract
Flue gas is treated by a regenerable wet scrubbing process to reduce sulfur- and nitrogen oxides by reacting with a solution containing ammonium thiosulfate and hydroxide, and a ferrous chelating agent. A portion of the spent scrubber solution is regenerated by reaction with hydrogen sulfide, flashed to hydrolyze the polysulfide content, and then returned as regenerated solution to the principal scrubbing circuit.
