PSR sulfur recovery catalyst inonyanya kushandiswa klaus sulfur recovery unit, choto gasi yekuchenesa system, mudhorobha gasi rekuchenesa system, synthetic ammonia chirimwa, barium strontium munyu indasitiri, uye sulfur yekudzoreredza unit mumethanol chirimwa. Pasi pechiito checatalyst, Klaus reaction inoitwa kugadzira indasitiri sarufa.
Iyo sulfur recovery catalyst inogona kushandiswa mune chero yakaderera reactor. Zvinoenderana nemamiriro ekushanda, iyo yakanyanya kutendeuka rate yeH2S inogona kusvika 96.5%, iyo hydrolysis rate yeCOS neCS2 inogona kusvika 99% uye 70% zvichiteerana, tembiricha inosvika 180 ℃ -400 ℃, uye yakanyanya tembiricha kuramba i600. ℃. Maitiro ekutanga eH2S neSO2 kugadzira element sulfur (S) uye H2O:
2H2S+3O2=2SO2+2H2O 2H2S+ SO2=3/XSX+2H2O
Iyo inzira isingadzivisiki kune yakakura sarufa yekudzoreredza mudziyo kushandisa iyo Claus + yekudzikisa-absorption process (inomiririrwa neiyo SCOT process). Nheyo huru yeSCOT sarufa yekudzoreredza maitiro ndeye kushandisa kuderedza gasi (senge hydrogen), kuderedza ese asiri-H2S sulfur makomisheni akadai seS02, COS, CSS mugasi remuswe wesarufa yekudzoreredza mudziyo kuenda kuH2S, wozotora nekubvisa H2S. kuburikidza neMDEA mhinduro, uye pakupedzisira dzokera kune asidhi gasi rinopisa choto chesarufa yekudzoreredza mudziyo kuti uwedzere kudzoreredza sarufa. Iyo gasi yekuburitsa kubva pamusoro peiyo shongwe yekunyura ine chete trace sulfide, iyo inoburitswa mumhepo kuburikidza ne incinerator pakupisa kwakanyanya.
