Ukukhiqizwa kwe-hydrogen ngegesi yemvelo inezinzuzo zezindleko eziphansi kanye nomphumela wokulinganisa. Ucwaningo kanye nentuthuko yobuchwepheshe obusha obuthuthukisiwe bokukhiqizwa kwe-hydrogen kusuka kugesi yemvelo kuyisiqinisekiso esibalulekile sokuxazulula inkinga yomthombo we-hydrogen oshibhile. Njengamandla ezimboni asezingeni eliphezulu futhi ahlanzekile, igesi yemvelo inezinto zokusetshenziswa ezibalulekile enqubweni yokuthuthukiswa kwamandla eShayina. Ngesikhathi esifanayo, futhi iyinto yokusetshenziswa eyisisekelo yemikhiqizo eminingi yamakhemikhali yesibili.
Njengomkhiqizo wesibili wamakhemikhali, i-hydrogen isetshenziswa kabanzi embonini yezemithi, yamakhemikhali amahle, kagesi kanye nekagesi. Ikakhulukazi, i-hydrogen, njengophethiloli okhethwayo wamaseli kaphethiloli, izoba namathuba emakethe abanzi emkhakheni wezokuthutha kanye nokukhiqizwa kwamandla esikhathini esizayo futhi izoba nesikhundla esibaluleke kakhulu esakhiweni samandla esizayo. Izindlela zokukhiqiza i-hydrogen zendabuko, njengokuguqulwa komusi we-hydrocarbon okhanyayo, i-electrolysis yamanzi, ukuqhekeka kwe-methanol, i-gasification yamalahle kanye nokubola kwe-ammonia, sezivuthiwe. Kodwa-ke, kunezinkinga ezithile, njengezindleko eziphakeme, izinga lokukhipha eliphansi, ukusebenza kahle okuphansi kwabasebenzi, eyodwa ephezulu kanye nezimbili eziphansi. Enqubweni yokukhiqizwa kukawoyela negesi eLiaohe Oilfield, kunezinsiza ze-hydrocarbon ezifana negesi eyomile kanye ne-naphtha. Ukukhiqizwa kwe-hydrogen ngale ndlela kungakhulisa ukusetshenziswa kwezinsiza. Ngaphezu kwalokho, ingxenye eyinhloko yegesi yemvelo ehlobene yi-methane, engaguqulwa ibe yi-hydrogen nge-hydrocarbon steam, ngobumsulwa bokukhiqiza obuphezulu kanye nokusebenza kahle kokukhiqiza okuphezulu.
Izinqubo eziyinhloko zokucubungula igesi yemvelo zifaka phakathi ukuhluzwa komoya kanye ne-vacuum, ukuqhekeka kwe-catalytic, ukuguqulwa kwe-catalytic kanye nokukhiqizwa kwe-aromatics. Ngesikhathi esifanayo, kufaka phakathi ukusetshenziswa kwegesi yemvelo, ukuqoqa kanye nokuhlanzwa, ama-alkanes kanye nomusi kugesi yemvelo kusabela ngamakhemikhali ngaphansi kwengcindezi ethile, izinga lokushisa eliphezulu kanye ne-catalyst.
Ngemva kokushintshana kokushisa kubhoyila yemali, igesi eguquliwe ingena esithandweni sokushintsha ukushintsha i-Co ibe yi-H2 kanye ne-CO2. Ngemuva kwalokho, ngemva kokushintshana kokushisa, ukujiya kanye nokuhlukaniswa kwamanzi anomusi, igesi idlula ngokulandelana embhoshongweni wokumunca ohlonyiswe ngama-adsorbents amathathu athile ngokulawula uhlelo, kanti i-N2 co CH4 CO2 icindezelwa futhi imuncwe yi-pressure swing adsorption (PSA) ukuze ikhiphe i-hydrogen yomkhiqizo, inciphise ukucindezeleka futhi ihlaziye ukuze ikhulule ukungcola futhi ivuselele i-adsorbent.
