A method, apparatus and system for treating a stream containing H2S are disclosed. A preferred method comprises mixing the stream containing H2S with a light hydrocarbon stream and an oxygen containing stream to form a feed stream; contacting the feed stream with a catalyst while simultaneously raising the temperature of the stream sufficiently to allow partial oxidation of the H2S and partial oxidation of the light hydrocarbon to produce a product stream containing elemental sulfur, H2O, CO and hydrogen, and cooling the product stream sufficiently to condense at least a portion of the elemental sulfur and produce a tail gas containing CO, H2, H2O and any residual elemental sulfur, and any incidental SO2, COS, and CS2 from the hydrocarbon stream or produced in the process. The tail gate is contacted with a hydrogenation catalyst so that CO is then reacted with water to produce CO2 and hydrogen and any elemental sulfur, SO2, COS, and CS2 in the tail gas is preferably converted into H2S. The resulting H2 and H2S-containing tail gas stream is then contacted with an alkanolamine absorber to remove the H2S, producing a hydrogen stream which may be compressed and further purified for use in a hydrogen consuming process.
