Ngabe igesi ye-helium ingakhiqizwa?
Yebo, okwamanje kukhona izindlela ezine zokulungiselela
Indlela yokuvumelanisa: Indlela yokuvumelanisa isetshenziswa embonini ukuze ikhiphe i-Helium kusuka kugesi yemvelo. Inqubo yale ndlela ifaka ukwenziwa kokuhlehlisa nokuhlanzwa kwegesi yemvelo, ukukhiqizwa kwe-helium enzima nokucwengiswa kwe-helium ukuthola i-helium ehlwilika engu-99.99%.
Indlela yokwehlukanisa komoya: Ngokuvamile, indlela eguquguqukayo ye-fractional isetshenziselwa ukukhipha i-helium ye-halium ne-neon exubekile kusuka kudivayisi yomoya, kanye negesi ehlanzekile negesi exubile kukhiqizwa kusuka kugesi ye-halium ne-neon exubile. Ngemuva kokuhlukaniswa kanye nokuhlanzwa, kutholakala i-helium emsulwa e-99.99%.
Indlela ye-Hydrogen Liquefaction indlela: embonini, indlela ye-hydrogen we-liquefaction isetshenziselwa ukukhipha i-helium kusuka kugesi yomsila we-ammonia synthesisis. Inqubo yale ndlela i-adsorption ephansi yokushisa yokususa i-nitrogen, ukususwa kabusha ukuze uthole ukususwa kwe-crude helium kanye ne-oxygen catalytic ukuze uthole i-helium engu-99.99%.
Indlela ephezulu yokuhlanza i-helium: 99.99% Pure alulimoni kuhlanzwa futhi ngokwenza i-carbon adsorption ecushiwe ukuthola i-helium evukile ephakeme.
Okokuqala, mayelana nezinqolobane zezinsiza kanye nekhwalithi, nakuba kune-helium esitsheni sethu, okuqukethwe okutholakala kuze kube manje kusekuncane kakhulu uma kuqhathaniswa nomhlaba, kuphela 11 × 10 ^ 8 cubic metres, okulinganiselwa ku-2.1% yenani lomhlaba wonke. Ngokuphambene, ukusetshenziswa kwe-helium ezweni lami kunezinga lokukhula eliphakathi kwe-11% kusukela ngo-2014 kuya ku-2018. Kungabonakala ukuthi izindawo zokugcina i-helium zaseChina azanele ukusekela ukusetshenziswa okukhulu. Noma ngabe ithuthukisiwe, iningi layo lisadinga ukuthembela ekuthengeni kwamanye amazwe. Ngaphezu kwalokho, ikhwalithi ye-helium ehloliwe okwamanje impofu, ayifinyeleli ezingeni lezohwebo, futhi noma imayini, ayikwazi ukusetshenziswa. Okwesibili udaba lwemishini yokuthuthukisa nokusebenza kahle, ngokombono wemishini yokukhipha igesi yemvelo ye-helium. Mancane kakhulu amadivaysi okukhipha i-helium ezweni lami, njengeDolobha lase-Dongxingchang, i-Rongxian County, Isifundazwe sase-Sichuan. Le divayisi yakhiwe kabusha ngo-2011 futhi inesibopho sokuhlanzwa kwe-helium. Ukuhlanzeka kwe-helium engahluziwe ekhiqizwa cishe ku-80%. Khona-ke i-helium engahluziwe idinga ukuhanjiswa iye e-Chengdu Natural Gas Chemical Plant ukuze iqhubeke nokuhlanzwa, ngokukhishwa konyaka okungu-20×10^4 cubic metres we-helium ehlanzekile. Ngakho-ke, imishini kanye nokusebenza kahle kokuhlanza nakho kwenza kube nzima ngathi ukukhiqiza i-helium ngokwethu, ngakho-ke singathembela kuphela ekuthengeni kwamanye amazwe.
Akuwona ukulethwa okungenamkhawulo kwezinsizakusebenza. Njengamanje, isidingo somhlaba wonke se-Helium siyanda ngokushesha, kepha ukuhlinzekwa kwayo kulinganiselwe kakhulu. Lokhu kusho ukuthi kudingeka sisebenzise le nto eyigugu ngokucophelela futhi sithole ezinye izindlela zokuhlangabezana nezidingo zethu ezikhulayo.
Ngoba i-hydrogen ne-helium ngamagesi alula kakhulu. I-Helium ingugesi we-inert, kepha i-hydrogen iyasebenza kakhulu, iyavutha futhi iqhuma. Ama-hydrogen airship aqedwa ngenxa yezizathu zokuphepha.
Yebo, i-Helium III yamanje itholakala ngokubola kwe-tritium. Ukuthi nje i-tritium manje itholakala ngokufaka i-lithium VI ku-reactor ye-nuclear fission.
