PROCESS FOR IN-SITU PRODUCTION OF LOW DISSOLVED HYDROGEN SULFIDE, DEGASSED, SULFUR FROM CLAUS SULFUR RECOVERY

摘要

A process of producing degassed liquid sulfur within a horizontal sulfur condenser may include condensing a portion of a Claus process gas introduced into a condenser tube to produce liquid sulfur; creating first and second chambers above a liquid sulfur reservoir with a baffle; passing the liquid sulfur and the Claus process gas into the first chamber; forcing the Claus process gas from the liquid reservoir within the first chamber to the second chamber; causing a chemical reaction between dissolved hydrogen sulfide in the liquid sulfur and sulfur dioxide from the Claus process gas on a catalyst to produce elemental sulfur and reducing the dissolved H2S content of the remaining sulfur; converting hydrogen sulfide by a Claus reaction; decomposing polysulfanes to hydrogen sulfide and sulfur, freeing elemental sulfur from hydrogen sulfide; forcing the Claus process bubbles from the liquid reservoir into the second chamber above the liquid reservoir.

主权项

1. A process of producing degassed liquid sulfur within a sulfur condenser, comprising:
providing a Claus process gas inlet in a first end of a casing of the sulfur condenser; providing a Claus process gas outlet in a second end of the casing of the sulfur condenser; providing a liquid sulfur outlet in a second end of the casing of the sulfur condenser; providing a condenser tube within the sulfur condenser between the first end of the casing and the second end of the casing; introducing a Claus process gas through the Claus process gas inlet, into the condenser tube, and through an interior of the condenser tube from a condenser tube inlet to a condenser tube outlet; condensing a portion of the Claus process gas within the condenser tube to produce condensed elemental sulfur; and passing the liquid elemental sulfur and the Claus process gas into a liquid reservoir proximate the second end of the casing.
