Abstract

PURPOSE: To keep absorbent content of absorbing soln. constant by crystallization and sparation of dithionate formed in the absorbing soln. , by thermal decomposition of the dithionate into SO2 and alkali sulfate, which is reduced to alkli sulfide, then by converting the alkali sulfide into alkali cabonate, which is circulated and is reutiliz d.
