Removal of SO2 and Production of Sulfur from Smelter ...

· . The proposed process for removing SO2 and producing sulfur from smelter gases is based upon the phenomena that when SO2 and H2S are absorbed in a suitable aqueous or organic liquid, they react rapidly, even at room temperature, to form elemental sulfur and water according to the stoichiometry shown in reaction 1.
