Abstract
1289696 Flue gas desulphurization ESSO RESEARCH & ENG CO 8 Dec 1969 [24 Dec 1968] 59740/69 Heading C1A A process for the removal of SO 2 from fluegases comprises contacting the flue gas with a copper-containing absorbent to absorb at least 90% of the SO 2 present, regenerating the absorbent with a reducing gas to recover the SO 2 , oxidizing any H 2 and CO present to H 2 O and CO 2 , drying the gas and converting the SO 2 to SO 3 and absorbing the SO 3 in sulphuric acid. The flue gas may be derived from the burning of coal or oil, and is preferably contacted with the absorbent at a space velocity of 2000 to 15,000 v./v./hr. at a maximum pressure drop of 5 inches water gauge. The absorbent may be a copper or copper oxide on a carrier, e.g. alumina, zirconia-kieselguhr, silica and silicaalumina. The preferred reducing gas for the regeneration process is a steam/hydrogen/CO/ CO 2 mixture derived from the catalytic reform- ing of methane, other suitable reducing gases include CO and hydrocarbon mixtures in the C 6 -C 14 range. The absorbent may be given an inert gas purge at the start and finish of the regeneration stage. The regenerated SO 2 gas, after oxidation of the residual H 2 and CO to water and CO 2 , and drying is converted to SO 3 and worked up into sulphuric acid by conventional means.
