Kunezindlela eziningi zokumisa izinqubo zeyunithi ezahlukahlukene zokucubungula igesi yemvelo noma ukwelapha isizinda segesi yemvelo. Okulandelayo ukumiswa okuvamile nokujwayelekile kwegesi yemvelo yemithombo yegesi engahlobene. Ibonisa ukuthi igesi yemvelo enganakiwe icutshungulwa kanjani ibe igesi yemvelo ukuze idayiswe eyiswa emakethe yomsebenzisi ekugcineni ngamapayipi.Uketshezi lwegesi yemvelo (NGL): i-propane, i-butane ne-C5+(leli igama elivamile le-pentane kanye ne-high molecular weight hydrocarbon ). Igesi yemvelo yoqobo ivamise ukuqoqwa eqenjini lemithombo eseduze bese kuqala icutshungulwa esitsheni esiyisihlukanisi endaweni lapho kuqoqwa khona.khipha amanzi ahlanzekile mahhala (susa amanzi kugesi yemvelo) kanye ne-condensate yegesi yemvelo. Amanzi e-condensate ngokuvamile athunyelwa endaweni yokuhluzwa, futhi amanzi aphathwa futhi aphathwe njengamanzi angcolile.
Bese, igesi ephakelayo ithuthelwa endaweni yokuhlanza igesi ngepayipi, lapho ukuhlanzwa kokuqala kuvamisesusa amagesi ane-asidi (i-hydrogen sulfide ne-carbon dioxide) .Ngenxa yochungechunge lokusebenza kanye nemikhawulo yemvelo yenqubo ye-amine, ubuchwepheshe obusha obusekelwe ekusetshenzisweni kwe-polymer membranes ukuhlukanisa i-carbon dioxide ne-hydrogen sulfide emifudlaneni yegesi yemvelo buye bathola ukwamukelwa okwengeziwe. Ulwelwesi luyakhanga ngoba aluwadli ama-reagents.Igesi ye-Acid (uma ikhona) ikhishwa ngolwelwesi noma ngokwelashwa kwe-amine, bese ithunyelwa kuyunithi yokutakula isibabule, eguqula i-hydrogen sulfide kugesi ye-asidi ibe yi-elemential sulphur noma i-sulfuric acid. Phakathi kwezinqubo ezingasetshenziswa kulokhu kuguqulwa, inqubo kaClaus iyinqubo eyaziwa kabanzi kakhulu yokuthola isibabule esiyisisekelo, kuyilapho inqubo yokuxhumana evamile kanye ne-WSA (inqubo ye-sulfuric acid emanzi) iwubuchwepheshe obusetshenziswa kakhulu ekubuyiseni i-sulfuric acid. Inani elincane legesi ye-asidi lingelashwa ngokushiswa.
Igesi eyinsalela evela kunqubo kaClaus ngokuvamile ibizwa ngokuthi i-tail gas, bese igesi ihlanzwa endaweni yokwelapha igesi yomsila ukuze kubuyiselwe insalela yesulphur compound bese iphinda isetshenziswe kabusha ibuyiselwe ku-Claus unit. Ngokufanayo, kunezinqubo eziningi ezingasetshenziswa ukwelapha igesi yomsila weyunithi yeClaus. Ngenxa yalesi sizathu, inqubo ye-WSA nayo ifaneleka kakhulu ngoba ingakwazi ukuqhuba ukwelashwa kokuzifudumeza ngegesi yomsila.
Isinyathelo esilandelayo sesitshalo sokwelapha igesi ukusebenzisa ukumuncwa okuvuselelekayo ku-liquid triethylene glycol (TEG), eyaziwa ngokuthi i-ethylene glycol dehydration, deliquescent chloride desiccant, noma i-pressure swing adsorption (PSA) idivayisi esebenzisa i-adsorbent eqinile yokukhangisa kwamanzi avuselelekayo ukuze kukhishwe i-adsorption yamanzi evuselelekayo. umhwamuko ovela kugesi. Ezinye izinqubo ezintsha, njengokuhlukaniswa kolwelwesi, nazo zingacatshangelwa.
I-Mercury ibe isikhishwa kusetshenziswa inqubo ye-adsorption efana nekhabhoni ecushiwe noma isisefo semolekyuli esivuselelekayo.
Nakuba kungavamile, ngezinye izikhathi izinqubo ezintathu zisetshenziselwa ukususa nokwenqaba i-nitrogen:
- Inqubo yezinga lokushisa eliphansi (idivayisi yokukhipha i-nitrogen ) isebenzisa i-distillation enezinga lokushisa eliphansi. Uma kunesidingo, inqubo ingashintshwa ukuze kubuyiselwe i-helium.
- Enqubweni yokumuncwa, amafutha anomzimba noma i-solvent ekhethekile isetshenziswa njenge-absorbent.
- Inqubo ye-adsorption isebenzisa i-carbon activated noma i-molecular sieve njenge-adsorbent. Ukusebenza kwale ndlela kungase kube nomkhawulo ngoba kuthiwa kubangela ukulahleka kwe-butane nama-hydrocarbons asindayo.
