Procedure

This example relates to the treatment of a sulfuric waste water containing 150 kmoles of sulfuric acid and 45 kmoles of metal sulfates (line 51) by means of a sulfitic solution containing 75 kmoles of ammonium sulfite and 75 kmoles of ammonium bisulfite (line 52), in reactor (53). 150 kmoles of SO2 evolve, 75 kmoles of ammonium sulfate and 75 kmoles of ammonium bisulfate (line 55) are produced according to the reaction:
