| titleOfInvention | Improved regeneration method for process which removes hydrogen sulfide from gas streams |
| abstract | The hydrogen sulfide containing gas is contacted with the absorbent liquid 26 containing the tertiary amine to absorb the hydrogen sulfide into the absorbent liquid in the absorption tower 11, and the absorbed liquid / hydrogen sulfide mixture is transferred to the reactor 15 [in reactor 15, 3 The secondary amine promotes the reaction of converting hydrogen sulfide into polysulfide through the reaction with sulfur], and transfers the polysulfide solution from the reactor 15 to the regeneration tower 10 (in the regeneration tower 10, the polysulfide is Conversion to elemental sulfur by reaction with air 9] and at least a portion of solution 25 containing not only elemental sulfur but also sulfate and thiosulfate groups is passed to mixer 36 (in mixer 36, When (25) comes into contact with gaseous ammonia, the sulfate and thiosulfate groups in solution 25 react with gaseous ammonia to produce ammonium sulfate and ammonium thiosulfate which will subsequently be removed from the solution. , The remainder of the solution 25 by passing the sulfur recovery zone 14, the gas stream (22) is provided a method for removing hydrogen sulphide from (for example, natural gas or fuel gas). A portion of the solution from which ammonium sulfate and ammonium thiosulfate have been removed is reunited with a portion of solution 25 that is transferred to the sulfur recovery region 14. The solution produced from the sulfur recovery zone 14 is recycled back to the absorption tower 11. |
