摘要： A method and apparatus for eliminating COS and/or CS2 from a hydrocarbon-containing feed stream, and further eliminating H2S from such feed stream or converting all sulfur species in such feed stream to H2S and SO2 to allow for easy subsequent conversion of such H2S and SO2 to elemental sulfur in a Claus reaction. The method comprises: (i) injecting water so that the feed stream contains greater than 10 vol % (water equivalent); (ii) passing the feed stream through catalyst means which hydrogenates COS and/or CS2 to H2S; (iii) injecting O2 so that the stoichiometric ratio of O2 to H2S is at least 0.5:1.0; (iv) passing the stream though a reaction zone having oxidation catalyst means which oxidizes H2S to elemental sulfur or SO2 (depending on the amount of oxygen and water added); where the temperature of the reaction zone is above the elemental sulfur dew point.

摘要： A method of reducing sulfur compounds from an incoming gas stream, comprising flowing the gas stream over a hydrolysis catalyst to convert COS and CS2 to H2S and reduce SO2 to elemental sulfur to form an effluent stream; providing an acidic gas removal unit comprising an absorbent; flowing said effluent stream over said absorbent to produce a stream free of acidic gases; applying an acidic-gas desorption mode to said acidic-gas rich absorbent to produce an acidic gas stream; introducing oxygen to said acidic gas-rich stream; providing a direct oxidation vessel containing catalyst suitable for catalyzing the oxidation of the H2S to sulfur wherein the temperature of the vessel is at or above the sulfur dew point at the reaction pressure; and flowing said acidic gas-rich stream over said catalyst to produce a processed stream having a reduced level of sulfur compounds.
