Abstract

PURPOSE: To recover exhaust gas contg. SO2 and NOx as a useful resource, by thermal decomposition of alkali dithionate, a by-product, accumulated in absorption soln., which has treated the SO2 and the NOx simultaneously, with reducing agent to convert it into alkali sulfide and a gas contg. SO2 and CO2.
