A method and system for liquid sulfur degassing is disclosed. The method and system generally involve degassing liquid sulfur in a degassing vessel, and the level of the liquid sulfur in the degassing vessel is controlled in the degassing vessel by determining the level of liquid sulfur in the degassing vessel.

Liquid sulfur degassing

Contemplated systems and methods for removing polysulfides and hydrogen sulfide from liquid sulfur of a Claus plant include (a) physically separated steps of catalytic decomposition of polysulfides and gas stripping, or (b) use of the stripping gas as the continuous phase in a packed column with decomposition catalyst to so avoid catalyst attrition.

Systems and methods for degassing of sulfur

Disclosed is a reactor, a retained catalyst structure, and a method for increasing the rate of decomposition of polysulfides and removal of hydrogen sulfide in liquid sulfur. The reactor, the retained catalyst structure, and the method include a retained catalyst structure arranged and disposed for contacting a first stream and a second stream in a reactor including a catalyst. The catalyst increases the rate of decomposition of polysulfides and facilitates the removal of hydrogen sulfide in the liquid sulfur of the first stream with the second stream. The first stream includes liquid sulfur containing polysulfides and dissolved hydrogen sulfide. The second stream includes an inert gas or a low oxygen-containing gas.
