    Spent Acid Recovery Process And Plant Design

    Regenerating spent sulfuric acid consists of four primary steps. 1. Decomposition of Spent Acid 2. SO 2 gas cooling cleaning and conditioning 3. Conversion of SO 2 to SO 3 4. Absorption of SO 3 into H 2 SO 4. Spent acid andor hydrogen sulfide is decomposed by combusting the spent acid and hydrogen sulfide gases in a decomposition furnace. This produces SO 2 gas. Fuel is burned along with the
