Abstract: 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.

Abstract: 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.
