Ukuveliswa kwe-hydrogen ngegesi yendalo ineengenelo zexabiso eliphantsi kunye nesiphumo sobukhulu. Uphando kunye nophuhliso lwetekhnoloji entsha yenkqubo ephucukileyo yokuvelisa i-hydrogen kwigesi yendalo sisiqinisekiso esibalulekileyo sokusombulula ingxaki yomthombo we-hydrogen ongabizi. Njengamandla emveliso asemgangathweni ophezulu kwaye acocekileyo, igesi yendalo inezinto ezibalulekileyo zokwenziwa kwenkqubo yophuhliso lwamandla eTshayina. Kwangaxeshanye, ikwayizinto ezisisiseko zokwenziwa kweemveliso ezininzi zeekhemikhali.
Njengemveliso yesibini yeekhemikhali, i-hydrogen isetyenziswa kakhulu kumashishini asebenzisa amayeza, amachiza amancinci, e-elektroniki kunye nombane. Ngokukodwa, i-hydrogen, njenge-fuel ekhethwayo kwiiseli zepetroli, iya kuba namathuba emarike abanzi kwicandelo lokuthuthwa kunye nokuveliswa kwamandla kwixesha elizayo kwaye iya kuba nesikhundla esibaluleke ngakumbi kwisakhiwo samandla kwixesha elizayo. Iindlela zemveli zokuvelisa i-hydrogen, ezinje ngokuguqulwa komphunga we-hydrocarbon olula, i-electrolysis yamanzi, ukuqhekeka kwe-methanol, i-gasification yamalahle kunye nokubola kwe-ammonia, zivuthiwe. Nangona kunjalo, kukho iingxaki ezithile, ezinje ngeendleko eziphezulu, izinga eliphantsi lokukhupha, ukusebenza kakuhle kwabasebenzi, enye ephezulu kunye nezimbini eziphantsi. Kwinkqubo yokuveliswa kweoyile negesi kwiLiaohe Oilfield, kukho izixhobo ze-hydrocarbon ezifana negesi eyomileyo kunye ne-naphtha. Ukuveliswa kwe-hydrogen ngale ndlela kunokwandisa ukusetyenziswa kwezixhobo. Ngaphezu koko, inxalenye ephambili yegesi yendalo ehambelana nayo yi-methane, enokuguqulwa ibe yi-hydrogen ngumphunga we-hydrocarbon, ngococeko oluphezulu lwemveliso kunye nokusebenza kakuhle kwemveliso.
Iinkqubo eziphambili zokucubungula igesi yendalo ziquka ukucocwa komoya kunye ne-vacuum, ukuqhekeka kwe-catalytic, ukuhlaziya i-catalytic kunye nokuveliswa kwe-aromatics. Kwangaxeshanye, kubandakanya ukusetyenziswa kwegesi yendalo, ukuqokelela kunye nokucoca, ii-alkanes kunye nomphunga kwigesi yendalo zisabela ngokweekhemikhali phantsi koxinzelelo oluthile, ubushushu obuphezulu kunye ne-catalyst.
Emva kokutshintshana kobushushu kwibhoyila yentlawulo, igesi eguquliweyo ingena kwi-shift oven ukuze itshintshe i-Co ibe yi-H2 kunye ne-CO2. Emva koko, emva kokutshintshana kobushushu, ukufuma kunye nokwahlulwa kwamanzi ngomphunga, igesi idlula ngokulandelelana kwi-adsorption tower exhotyiswe ngee-adsorbents ezintathu ezithile ngolawulo lwenkqubo, kwaye i-N2 co CH4 CO2 icinezelwa kwaye ifunxwe yi-pressure swing adsorption (PSA) ukuze ikhuphe i-hydrogen yemveliso, i-depressurize kwaye ihlalutye ukuze ikhuphe ukungcola kwaye iphinde ivelise i-adsorbent.
