Abstract:
1. A reactor, comprising: a first inlet for a first stream including liquid sulfur containing polysulfides and dissolved hydrogen sulfide; a second inlet for a second stream of an inert gas or a low oxygen containing gas; a retained catalyst structure arranged and disposed to facilitate contact between the first stream, the second stream, and the retained catalyst structure; the retained catalyst structure having a catalyst material affixed, coated, trapped, or supported such that movement of the catalyst is limited; and wherein the amount of catalyst is sufficient to increase the rate of decomposition of the polysulfides and facilitate removal of hydrogen sulfide produced by decomposing polysulfides and hydrogen sulfide present in the liquid sulfur of the first stream with the second stream, thereby decreasing total polysulfides and hydrogen sulfide content in the liquid sulfur to less than 5 ppmw.
