| titleOfInvention | Process for producing ammonium thiosulphate |
| abstract | A process is provided for removing hydrogen sulphide and ammonia out of a gas (12), such as sour water stripper gas. The hydrogen sulfide and ammonia-containing gas is fed into a first reactor (38) where only a portion of the hydrogen sulfide and ammonia are sorbed out of the gas into an ammonium sulfite and ammonium bisulfite-containing scrub solution (40), where the sorbed hydrogen sulfide and sorbed ammonia react with the sulfite values within the scrub solution to form ammonium thiofulfate product. The residual, unsorbed hydrogen sulfide and unsorbed ammonia from the gas are fed into a water scrubber (74), where water, ammonia and hydrogen sulfide react to form ammonium bisulfide product and a gas containing residual, unreacted hydrogen sulfide (78). This residual, unreacted hydrogen sulfide may be combusted into sulfur dioxide. This sulfur dioxide (or sulfur dioxide from another source) (84) is mixed with the scrub solution (58) in a second reactor (82) where it reacts with the ammonia therein to provide the ammonium sulfite and ammonium bisulfite necessary for the production of ammonium thiosulfate product. |
