Abstract

PURPOSE: To accomplish recovery or regeneration of SO2 and an absorption liquid in a continuous, closed system through a sequential combination of process composed of the absorption of SO2 in a waste gas by a liquid containing a chelate complex and the recovery of concentrated SO2 and a regenerated chelate complex from the absorption liquid.
