Abstract
A process for removing sulfur from a HS-containing gas stream is disclosed. A preferred embodiment of the process comprises incorporating a short contact time catalytic partial oxidation reactor, a cooling zone, and a condenser into a conventional refinery or gas plant process, such as a natural gas desulfurizer, a hydrotreater, coker or fluid catalytic cracker, in which sulfur removal is needed in order to produce a more desirable product. An HS-containing gas stream is fed into a short contact time reactor where the HS is partially oxidized over a suitable catalyst in the presence of Oto elemental sulfur and water.
