Abstract

PURPOSE: To recover accumulating SO2 -4 as high purity gypsum contained no iron, by drawing out a part of water solution, contained NH4HSO3 for NOX absorption and Fe(HSO3)2 and Fe in the above water solution is precipitated and is separated as FeSO3 and then, reacting quicklime etc. with remained water solution
