Abstract: A process is presented to treat a process stream containing a hydrocarbon (oil and/or gas) and hydrogen sulfide with a liquid treatment solution containing a sulfur dye catalyst. The process stream can be within a pipeline, wellbore, subsea pipeline or a wellhead that contains hydrogen sulfide where the liquid treatment solution is injected at a predetermined point to define a scavenger zone such that the sulfur dye catalyst in the liquid treatment solution causes the sulfide from the hydrogen sulfide to react with the catalyst. The hydrocarbon component is separated substantially free of the hydrogen sulfide from a spent treatment solution containing spent sulfur dye catalyst which can then be fed to an oxidation vessel where it is contacted with an oxygen containing gas causing the sulfide to oxidize to thiosulfate and converting the spent sulfur dye catalyst to regenerated sulfur dye catalyst.

Abstract: In a catalytic treatment process, mercaptans in sour hydrocarbon are oxidized to disulfide oils using an aqueous treatment solution containing a chelated polyvalent metal catalyst, alkali metal hydroxide, and the alkali metal salt of at least one alcohol in a non-dispersive mixing apparatus wherein an upgraded hydrocarbon containing the disulfide oils is produced.
