PSR sulfur recovery catalyst ikoreshwa cyane cyane mu ishami rishinzwe kugarura sulfur rya klaus, sisitemu yo gutunganya gaze mu itanura, sisitemu yo gutunganya gaze mu mijyi, uruganda rwa ammonia rukora, inganda z’umunyu wa barium strontium, n’ishami rishinzwe kugarura sulfur mu ruganda rwa methanol. Mu bikorwa bya catalyst, Klaus reaction ikorwa kugira ngo ikore sulfur mu nganda.
Katalyst yo kugarura sulfure ishobora gukoreshwa muri reactor iyo ari yo yose yo hasi. Dukurikije imiterere y'imikorere, igipimo ntarengwa cyo guhindura H2S gishobora kugera kuri 96.5%, igipimo cya hydrolysis cya COS na CS2 gishobora kugera kuri 99% na 70% uko bikurikirana, igipimo cy'ubushyuhe ni 180℃ -400℃, naho ubushyuhe ntarengwa bwo kwirinda ni 600℃. Uburyo bw'ibanze bwa H2S hamwe na SO2 mu gukora element sulfur (S) na H2O:
2H2S + 3O2 = 2SO2 + 2H2O 2H2S + SO2 = 3 / XSX + 2H2O
Ni ikintu kidasubirwaho ko igikoresho kinini cyo kugarura sulfure gikoresha uburyo bwa Claus + reduction-absorption (bugaragazwa n'uburyo bwa SCOT). Ihame nyamukuru ry'uburyo bwo kugarura sulfure ya SCOT ni ugukoresha gazi igabanya (nka hydrogen), kugabanya ibintu byose bitari H2S bya sulfure nka S02, COS, CSS mu mwuka w'inyuma w'igikoresho cyo kugarura sulfure kuri H2S, hanyuma bigakurura H2S binyuze mu muti wa MDEA, hanyuma bigasubizwa mu itanura ritwika gazi ikomoka kuri aside y'igikoresho cyo kugarura sulfure kugira ngo bikomeze kugarura sulfure. Imyuka iva hejuru y'umunara wo kugarura irimo sulfure nto gusa, isohoka mu kirere inyuze mu gikoresho cyo gutwika ku bushyuhe bwinshi.
