  • Process for the removal of sulfur dioxide from exhaust flue gases
    Patent number: 4113840
    Abstract: Sulfur dioxide is removed from exhaust flue gases continuously by contact with adsorbent, activated carbon, in aqueous slurry form, preferably in a venturi contactor. The carbon with adsorbed sulfur dioxide is partially dewatered and passed to an oxidation zone in which the sulfur dioxide is converted to sulfur trioxide and absorbed into the aqueous phase to form saleable sulfuric acid. The desorbed activated carbon is recycled to the venturi contactor.
