ABSTRACT:
A method is provided for removing SO.sub.2 from gas streams by its gas-phase reaction with a stabilized Criegee intermediate under conditions where a very large excess of water vapor is avoided, resulting in efficient scavenging of SO.sub.2 by the Criegee intermediate to form an adduct. The adduct reacts with water vapor to convert it directly to sulfuric acid, which is then separated from the gas stream. The Criegee intermediate may be generated in a variety of ways.
