· 2.1.3.6.2 H 2 O 2 Process. Use of H 2 O 2 can oxidize the SO 2 to SO 3 which is then used to produce sulfuric acid. However, due to the high cost of H 2 O 2 this process is not economical. H 2 O 2 is therefore used for oxidizing the remaining traces of (dissolved) SO 2 in the circulating acid in the plant.
