Eyunithi yokuncibilikisa igesi yemvelo, kunezindlela ezintathu ezivamile zokuhlanza, okuyi-alcohol amine method, i-hot potassium method (eyenziwe nge-benfied) kanye ne- indlela ye-sulfonol amine.
I-Mercury: ukuba khona kwe-mercury kungalimaza kakhulu imishini ye-aluminium. Lapho i-Mercury (kufaka phakathi i-mercury elemental, ama-ion e-mercury kanye nama-organic mercury compounds), i-aluminium izosabela namanzi ukuze ikhiqize imikhiqizo yokugqwala emhlophe eyimpuphu, okuzolimaza kakhulu izakhiwo ze-aluminium. Inani elincane kakhulu lokuqukethwe kwe-mercury lanele ukubangela umonakalo omkhulu emishinini ye-aluminium, kanti i-Mercury izobangela nokungcola kwemvelo kanye nokulimala kwabasebenzi ngesikhathi sokulungiswa. Ngakho-ke, okuqukethwe kwe-mercury kufanele kulinganiselwe ngokuqinile. Susa i-mercury Isimiso sisekelwe ekusabeleni kwe-mercury ne-sulfur ku-reactor ye-catalytic.
I-hydrocarbon esindayo: ibhekisela kuma-hydrocarbon angaphezu kuka-C5+. Kuma-hydrocarbon, lapho isisindo sama-molecule sishintsha sisuka kokuncane siye kokukhulu, iphuzu laso lokubila liyashintsha lisuka kokuphansi liye kokuphezulu. Ngakho-ke, emjikelezweni wokujiya kwegesi yemvelo, ama-hydrocarbon esindayo ahlala ejiya kuqala. Uma i-hydrocarbon esindayo ingahlukaniswanga kuqala, noma ihlukaniswe ngemva kokujiya, i-hydrocarbon esindayo ingase iqine futhi ivimbe imishini. Ama-hydrocarbon esindayo asuswa kancane ngesihlungo sama-molecule kanye nezinye izinto ezifaka amanzi emzimbeni ngesikhathi sokuphelelwa amanzi emzimbeni, kanti okunye kuhlukaniswa ngokuhlukaniswa kwe-cryogenic.
I-Cos: ingamanziswa ngamanzi amancane kakhulu ukuze yakhe i-H2S ne-CO2, okubangela ukugqwala emishinini. Kulula ukuyixuba ne-propane etholakele. Ngokuvamile isuswa kanye ne-H2S ne-CO2 ngesikhathi sokunciphisa i-acid.
I-Helium: igesi yemvelo ingumthombo oyinhloko we-helium futhi kufanele ihlukaniswe futhi isetshenziswe. Inenani eliphezulu lokusetshenziswa ngokuhlanganiswa kokuhlukaniswa kwe-membrane kanye nokuhlukaniswa kwe-cryogenic.
I-nitrogen: ukwanda kokuqukethwe kwayo kuzokwenza kube nzima kakhulu uketshezi lwegesi yemvelo. Indlela yokugcina ye-flash ivame ukusetshenziswa ekususweni okukhethekile ku-LNG.
Ingxenye eyinhloko yegesi yemvelo yi-methane (CH4), kanti izinga layo lokubila elijwayelekile lingu-111k (-162 ℃).
Ubuningi be-methane ewuketshezi endaweni yokubila ejwayelekile bungu-426kg / m3, kanti ubuningi be-methane ewugesi esimweni esijwayelekile bungu-0.717kg / m3, ngomehluko ophindwe izikhathi ezingaba ngu-600. Umehluko omkhulu ngevolumu yisona sizathu esiyinhloko sokugcina kanye nokuthuthwa kwegesi yemvelo encibilikisiwe.
