Njengamanje, izinqubo zokukhipha i-helium kugesi wemvelo ekhaya nakwamanye amazwe zifaka phakathi indlela ye-cryogenic, indlela ye-adsorption, indlela yokuhlukanisa ulwelwesi, noma inhlanganisela yezinqubo ezimbili noma ezintathu ezisetshenziswa ndawonye.
1) Indlela yokupholisa ngokujulile
Ukuhluza okubandayo okujulile kuyindlela evame ukusetshenziswa esitshalweni se-helium esiphakathi kuya kwesikhulu sokubuyisa igesi yemvelo. Umgomo ukusebenzisa i-nitrogen ewuketshezi njengesiqandisi (cishe -190 ℃) ukuze kancane kancane ama-hydrocarbon ahlanganisiwe nezinye izingxenye kugesi yemvelo, futhi ngenxa yezinga eliphansi kakhulu lokubila le-helium, ekugcineni lihlukana nezinye izingxenye zegesi yemvelo.
2) Indlela yokumunca ingcindezi yokushintshashintsha
I inqubo yokumuncwa kwengcindezi yokushintshashintsha (i-PSA) isebenzisa ama-adsorbent ahlukene ukumunca izingxenye zegesi yemvelo ngaphandle kwe-helium, ngaleyo ndlela ihlukanise imikhiqizo ye-helium. Ngokuvamile, imibhoshongo yokumunca i-PSA igcwele imibhede yokuhlukanisa yezinto ezahlukene zokumunca ukuze ibhekane nezingxenye ezahlukene kugesi yemvelo, njenge-silica gel noma imibhede ye-alumina yokususa amanzi, imibhede ye-carbon esebenzayo yokususa i-carbon dioxide, imibhede ye-zeolite yokususa i-methane ne-nitrogen, njalo njalo. Ngemva kokuba i-adsorbent igcwalise igesi yokungcola, izindlela ezifana ne-depressurization backflushing noma i-vacuum pumping zingasetshenziswa ukuxazulula igesi yokungcola, ngaleyo ndlela kubuyiselwe umsebenzi we-adsorbent.
3) Indlela yokuhlukanisa ulwelwesi
I-membrane yokuhlukanisa igesi iwubuchwepheshe obusha bokuhlukanisa. Izingxenye zegesi zidlulisela isisindo kumafilimu e-polymer (njengemicu ye-acetate, i-polypropylene, i-polysulfone, i-polyimide, njll.) ngokusekelwe esimisweni sokusabalala kokuncibilika. Ukuhlukaniswa kwengxenye ngayinye kutholakala ngokushintsha izinga lokuncibilika kanye nezinga lokusabalalisa kwezingxenye zegesi ezahlukene ezintweni ze-membrane. Lapho ingxube yamagesi amabili noma ngaphezulu idlula kwifilimu ye-polymer, izinga lokugcwala kwezingxenye ezifana ne-helium ne-hydrogen liphakeme kakhulu kunele-nitrogen, i-methane, namanye ama-hydrocarbon.
