    Abstract: A process for reducing hydrogen sulfide from a gas comprising contacting the gas with an aqueous scrubbing liquid recycled from a sour water stripper. The aqueous scrubbing liquid comprises ammonia. The contacting of the gas with the aqueous scrubbing liquid thereby produces a semi-sweet gas with reduced concentration of hydrogen sulfide and a rich liquid solution.

    Abstract: A water stream containing NH4HS is treated to produce elemental sulfur, an ammoniacal aqueous stream and a treated water stream by the steps of: (a) catalytically treating the water stream with an airstream to produce an effluent stream containing ammonium polysulfide, N2 and unreacted NH4HS; (b) separating the effluent stream from step (a) into a vent gas stream and a water stream; (c) decomposing the polysulfide contained in the water stream from step (b) to produce a vapor stream and a bottom stream containing elemental sulfur; (d) separating sulfur from the bottom stream from step (c) to form a treated water stream; (e) recovering a first portion of the treated water stream from step (d) as a product stream; (f) using a second portion of the treated water stream from step (d) to scrub the vent gas stream from step (b) in order to remove NH3 and H2S therefrom; (g) fractionating the overhead vapor stream from step (c) and the bottom stream from the scrubbing step to form an ammoniacal aqueous overhead stream and an aqueous bottom stream containing essentially all of the unreacted sulfide present in the effluent stream from the treating step; and, (h) recycling the bottom stream from step (g) to step (a). Key feature is the use of a scrubbing step on the vent gases from the treating step operated at a relatively low pressure and a relatively high-liquid gas loading, coupled with a combination scrubbing and fractionating step on the bottom stream from the scrubbing step and on the vapor stream from the polysulfide decomposition step. This combination scrubbing and fractionating step is operated at a relatively high pressure, thereby increasing the amount of H2S that can be absorbed. The principle advantages of the resulting process are significant improvements in the amount of ammonia and sulfur recovered and a substantial simplification of the overall process.

    Abstract: Inorganic, water-soluble oxysulfur compounds are reduced by contacting an aqueous solution of the oxysulfur compound and hydrogen with a bimetallic catalyst at reduction conditions. The bimetallic catalyst comprises catalytically effective amounts of a metallic sulfide selected from sulfides of the transition metals from group VI and of a metallic sulfide selected from the sulfides of the transition metals of group VIII combined with a porous carrier material. A specific example of the disclosed invention is a method for reducing an inorganic, water-soluble thiosulfate compound to a sulfide compound by contacting an aqueous solution of the thiosulfate compound and hydrogen, at reduction conditions, with a catalyst comprising a combination of catalytically effective amounts of molybdenum sulfide and of cobalt sulfide with a porous carrier material.

    Abstract: The present invention is directed to a method and system for integrating a catalyst regeneration system with a plurality of hydrocarbon conversion apparatuses, preferably, a plurality of multiple riser reactor units. One embodiment of the present invention is a reactor system including a plurality of reactor units, at least one reactor unit preferably comprising a plurality of riser reactors. The system also includes a regenerator for converting an at least partially deactivated catalyst to a regenerated catalyst. A first conduit system transfers the at least partially deactivated catalyst from the reactor units to the regenerator, and a second conduit system transfers regenerating catalysts from the regenerator to the plurality of reactor units. Optionally, catalysts from a plurality of hydrocarbon conversion apparatuses may be directed to a single stripping unit and/or a single regeneration unit.
