Kunezindlela eziningi zokuhlela izinqubo ezahlukene zamayunithi zokucubungula igesi yemvelo noma isitshalo segesi yemvelo. Okulandelayo ukucushwa okuvamile nokujwayelekile kwegesi yemvelo yemithombo yegesi engahlobene. Kubonisa indlela igesi yemvelo engaphathwanga ecutshungulwa ngayo ibe yigesi yemvelo ukuze ithengiswe ethuthwa emakethe yomsebenzisi wokugcina ngamapayipi. Uketshezi lwegesi yemvelo (NGL): i-propane, i-butane kanye ne-C5+ (leli igama elivamile le-pentane kanye ne-hydrocarbon enesisindo esikhulu samamolekyuli). Igesi yemvelo yokuqala ivame ukuqoqwa eqenjini lemithombo eseduze bese icutshungulwa kuqala esitsheni sokuhlukanisa endaweni yokuqoqwa ukuze susa amanzi ahlanzekile mahhala (susa amanzi kugesi yemvelo) kanye negesi yemvelo econdensate. Amanzi acondensate avame ukuthunyelwa endaweni yokuhluza, futhi amanzi aphathwa futhi aphathwe njengamanzi angcolile.
Ngemuva kwalokho, igesi yokuphakelayo ithuthwa iye esitshalweni sokwelapha igesi ngepayipi, lapho ukuhlanzwa kokuqala kuvame ukuba khona susa amagesi e-asidi (i-hydrogen sulfide kanye ne-carbon dioxide). Ngenxa yochungechunge lokusebenza kanye nemikhawulo yemvelo yenqubo ye-amine, ubuchwepheshe obusha obusekelwe ekusetshenzisweni kwama-membrane e-polymer ukuhlukanisa i-carbon dioxide kanye ne-hydrogen sulfide emifudlaneni yegesi yemvelo buye bamukelwa kakhulu. I-membrane iyathandeka ngoba ayidli ama-reagents. Igesi ye-asidi (uma ikhona) isuswa ngokwelashwa kwe-membrane noma i-amine, bese ithunyelwa kuyunithi yokubuyisa i-sulfur, eguqula i-hydrogen sulfide kugesi ye-asidi ibe yi-sulfur noma i-sulfuric acid. Phakathi kwezinqubo ezingasetshenziswa kulezi zinguquko, inqubo ye-Claus yiyona inqubo eyaziwa kakhulu yokubuyisa i-sulfur eyisisekelo, kuyilapho inqubo yokuxhumana yendabuko kanye ne-WSA (inqubo ye-sulfuric acid emanzi) ubuchwepheshe obusetshenziswa kakhulu bokubuyisa i-sulfuric acid. Inani elincane legesi ye-asidi lingaphathwa ngokushisa.
Igesi eseleyo evela enqubweni yeClaus ivame ukubizwa ngokuthi igesi yomsila, bese igesi iphathwa eyunithi yokwelapha igesi yomsila ukuze kutholakale i-residual sulfur compound bese iphinda isetshenziswe kuyunithi yeClaus. Ngokufanayo, kunezinqubo eziningi ezingasetshenziswa ukwelapha igesi yomsila yeyunithi yeClaus. Ngenxa yalesi sizathu, inqubo ye-WSA nayo ifaneleka kakhulu ngoba ingenza ukwelashwa kokuzifudumeza kugesi yomsila.
Isinyathelo esilandelayo sesitshalo sokwelapha igesi ukusebenzisa ukumuncwa okuvuselelwayo ku-triethylene glycol (TEG) ewuketshezi, eyaziwa ngokuthi i-ethylene glycol dehydration, i-deliquescent chloride desiccant, noma idivayisi ye-pressure swing adsorption (PSA) esebenzisa i-solid adsorbent ukuze kufakwe i-adsorption evuselelwayo ukuze kususwe umhwamuko wamanzi kugesi. Ezinye izinqubo ezintsha kakhulu, njengokuhlukaniswa kwe-membrane, nazo zingacatshangelwa.
I-Mercury isuswa kusetshenziswa inqubo yokumunca njenge-activated carbon noma i-renewable molecular sieve.
Nakuba kungavamile, ngezinye izikhathi enye yezinqubo ezintathu isetshenziswa ukususa nokulahla i-nitrogen:
- Inqubo yokushisa okuphansi (idivayisi yokususa i-nitrogen) isebenzisa ukuhluzwa okushisa okuphansi. Uma kudingeka, inqubo ingashintshwa ukuze kutholakale i-helium.
- Enkambisweni yokumunca, uwoyela ongenamafutha noma i-solvent ekhethekile isetshenziswa njengesimunci.
- Inqubo yokumunca isebenzisa i-activated carbon noma i-molecular sieve njenge-adsorbent. Ukusebenza kwale ndlela kungase kulinganiselwe ngoba kuthiwa ibangela ukulahleka kwe-butane nama-hydrocarbon asindayo.
