Process for in-situ production of low dissolved hydrogen sulfide, degassed, sulfur from claus sulfur recovery

Abstract

A process of producing degassed liquid sulfur within a vertical sulfur condenser may include providing a plurality of condenser tubes within an external casing; submerging exit ends of the plurality of condenser tubes within a liquid reservoir resulting in submerged exit ends of the plurality of condenser tubes; passing the Claus process gas into an inlet end of the plurality of condenser tubes; condensing the Claus process gas within the condenser tubes to produce condensed Claus process gas within the plurality of condenser tubes; and collecting the condensed Claus process gas in the liquid reservoir upon exiting of the condensed Claus process gas at an exit end of the plurality of condenser tubes. The process may further include converting hydrogen sulfide by the Claus reaction 2H2S+SO23/xSx+2H2O, and decomposing polysulfanes to hydrogen sulfide and sulfur, wherein elemental sulfur is freed from hydrogen sulfide.
