Abstract
An improvement in regenerative SO.sub.2 scrubbing systems which use sodium, potassium or ammonium carbonate to react with the SO.sub.2 to form sulfite, wherein a thiosulfate-rich aqueous solution of the carbonate is used to prevent oxidation of the sulfite to sulfate; to serve both as a source of the carbonate and as a source of sulfite-reducing agent; and finally to increase the salt concentration in the SO.sub.2 absorbent solution, to thereby permit operation of the scrubbing system at higher temperatures than those normally employed.
