Chemisorptive catalytic oxidation process for SO2 from smelting waste gases by Fe(II)
Chemisorption of SO2 from smelting plant exhaust gases in a single sieve plate column was investigated. Main parameters were SO2 and O2 gas and H2SO4, FeSO4 and Al2(SO4)3 liquid concentrations on reaction rate and equilibrium in FeII-EDTA solutions. Absence of inhibitors with this kind of flue gases promote fast kinetics. Optimal process conditions with 3% wt. FeSO4 catalyst up to 2000 PPM SO2. Maximum yield of 16% H2SO4 could be achieved considering optimal liquid/vapor ratio, oxygen surplus and insert salt concentrations.
