I-ALLY – Ubuchwepheshe Bokuhlanza I-COG Obuhamba Phambili E-China: Ukuhlaziywa Kwamasu Kokususwa Kwe-Carbon Ezimbonini

Ezindaweni zezimboni ezinkulu zasenyakatho yeShayina, izithunzi eziphakeme zezitshalo zokupheka bezilokhu ziyizimpawu zokukhiqiza kwezomnotho, kodwa futhi zithwala ubunzima bezinselele zemvelo. Njengoba ubusuku bufika phezu kwendawo evamile yokukhiqiza insimbi, ukukhanya okuphuzi kwama-oven e-coke kubonisa impikiswano yomlando: ukukhiqizwa okukhulu kwe-Coke Oven Gas (COG) njengomkhiqizo ongeziwe. Ngokomlando, iningi lale gesi lalivutha, okwaholela ekukhishweni okukhulu kwekhabhoni, noma lasetshenziswa ngendlela engasebenzi kahle njengophethiloli osezingeni eliphansi.

Namuhla, indaba iyashintsha. Ukuphuthuma komhlaba wonke kokuguqulwa kwamandla kuguqule le "mfucuza yezimboni" yaba yindawo yokuqoqwa kwengcebo yokukhiqizwa kwe-hydrogen. Inhliziyo yalolu shintsho ilaphoUbuchwepheshe Bokuhlanza I-COG Obuhamba Phambili Esikhathi Esizayo eShayina, into entsha ebalulekile ehlanganisa igebe phakathi kwemboni yendabuko esindayo kanye nekusasa elingenayo ikhabhoni. Ngokukhipha i-hydrogen ehlanzekile kakhulu ezingxubeni zegesi eziyinkimbinkimbi, lobu buchwepheshe bubhekana nendawo ebalulekile yokulahlekelwa kwemithombo embonini ngenkathi buhlinzeka ngomthombo kaphethiloli ozinzile, osendaweni yomnotho we-hydrogen osafufusa, ikakhulukazi emikhakheni yensimbi neyamakhemikhali.

Ushintsho Lomhlaba Wonke Oluya Ekususweni Kwekhabhoni Kwezimboni Nokuhlanganiswa Kwe-Hydrogen

Umkhakha wezimboni womhlaba wonke okwamanje usenkingeni, udlula ekuguqukeni okuyinkimbinkimbi kusuka ekuthembeleni kuphethiloli kuya ezinhlelweni zamandla ezisimeme. Izivumelwano zesimo sezulu samazwe ngamazwe zishukumise ukunyakaza komhlaba wonke okuya ekususeni i-carbonization, kugxilwe kakhulu emikhakheni "ekunzima ukuyinciphisa" njengokukhiqiza insimbi, ukuthuthwa kwemithwalo enzima, kanye nokucubungula amakhemikhali. Kulesi simo, i-hydrogen ivele njengomthwali wamandla wokugcina. IYurophu neNyakatho Melika zenze intuthuko enkulu ku-hydrogen eluhlaza, kodwa inselele esheshayo isalokhu iyizindleko kanye nobukhulu bokukhiqiza.

IShayina, njengomkhiqizi omkhulu kunabo bonke emhlabeni wensimbi ne-coke, ithatha isikhundla esiyingqayizivele kulo mzila womhlaba wonke. Imigomo kahulumeni waseShayina ethi “Dual Carbon”—ukuphakamisa ukukhishwa kwekhabhoni ngo-2030 nokufinyelela ukungathathi hlangothi kwekhabhoni ngo-2060—ibeke ingcindezi enkulu ezimbonini zendabuko ukuze zisungule izinto ezintsha. Umzabalazo oyinhloko wemboni awukona nje ukunciphisa ukukhishwa kwekhabhoni, kodwa ukwenza kanjalo ngendlela ephumelelayo kwezomnotho. Ukuhlanzwa kwe-COG kunikeza ikhambi elisebenzayo nelinomthelela omkhulu. Ngokucwenga igesi ecebile nge-hydrogen esivele ikhiqizwa ngesikhathi senqubo yokupheka, izimboni zinganciphisa kakhulu umthelela wazo wekhabhoni ngaphandle kokulinda ingqalasizinda ephelele ye-electrolysis ukuthi ivuthwe. Lokhu kugxila kwasekhaya kuhambisana nemizamo yamazwe ngamazwe yokukhulisa ukusebenza kahle kwezinsizakusebenza futhi kumelela itshe lesisekelo lokuphepha kwamandla kweqhinga laseShayina.

Izinzuzo Eziyinhloko Zokuhlanzwa Kwe-COG Emkhakheni Wamandla Wanamuhla

Inqubo yokuguqula igesi ye-coke oven eluhlaza ibe yi-hydrogen esezingeni likaphethiloli inzima kakhulu ngokobuchwepheshe, idinga ukususwa kokungcola okuyinkimbinkimbi njenge-tar, i-naphthalene, i-ammonia, ne-organic sulfur. Ukuvela kokuhlanzwa kwe-cog kuye kwaqhubekela phambili ekusebenzeni kahle okuphezulu kanye nokusetshenziswa kwamandla okuphansi. Izinhlelo zanamuhla manje zisebenzisa ubuchwepheshe obuthuthukisiwe be-Pressure Swing Adsorption (PSA), obuvumela ukuhlukaniswa okukhethiwe kwe-hydrogen ngezingcindezi ezahlukahlukene. Lobu buchwepheshe obukhethekile bokuhlanza i-cog kuCI-hina ihlanjululwe ukuze kufinyelelwe amazinga okuhlanzeka angaphezu kuka-99.999%, okuhlangabezana nezidingo eziqinile zemboni yezimoto zamaseli kaphethiloli we-hydrogen (HCV).

Esinye sezici ezivelele zezinhlelo zakamuva zokuhlanza i-cog ukuthi ziyazivumelanisa nezimo zokwakheka kwegesi yokudla eshintshashintshayo. Izinqubo zezimboni azivamile ukuguquguquka; ikhwalithi ye-COG eluhlaza ingahluka ngokuya ngezinhlobo zamalahle kanye namazinga okushisa e-oven. Amayunithi okuhlanza athuthukisiwe manje ahlanganisa izinhlelo zokulawula ezihlakaniphile eziqapha ukungena kwegesi ngesikhathi sangempela, zilungisa imijikelezo yokumunca ukuze kugcinwe ikhwalithi yokukhipha ehambisanayo. Ngaphezu kwalokho, ukuhlanganiswa kokuhlanzwa kwezigaba eziningi—kufaka phakathi ukwelashwa kwangaphambili, ukuhlanzwa kahle, kanye nezigaba zokugcina ze-PSA—kuqinisekisa ukuthi impilo ye-catalyst kanye ne-adsorbent ikhuliswa kakhulu, kunciphisa izindleko eziphelele zobunikazi kubasebenzi bezimboni. Lokhu kuvuthwa kobuchwepheshe ekuhlanzweni kwe-cog yikho okuvumela izigayo zensimbi ezinkulu ukuthi zishintshele kuma-energy hubs, zinikeze i-hydrogen ehlanzekile yemikhumbi yazo ye-logistics noma izimakethe zamandla zesifunda.

Ukuhlaziywa Kwamasu: Ukuhlanganisa Ubuchwepheshe Bokususa I-Carbon Ejulile

Ukususa i-carbonization akuyona ikhambi lomkhiqizo owodwa kodwa kuwumsebenzi ophelele wamasu. Ukuze kuthinteke ngempela indawo yezimboni, ukuhlanzwa kwe-cog kumele kubhekwe njengengxenye yesistimu ebanzi yokuphathwa kwamandla. Lokhu akubandakanyi nje kuphela ukukhishwa kwe-hydrogen kodwa futhi nokucindezelwa kwayo, ukugcinwa kwayo, kanye nokusetshenziswa kwayo ekugcineni. Indlela ebanzi yenkonzo yezimboni ihlanganisa yonke impilo yephrojekthi—kusukela ekwakhiweni kobunjiniyela bokuqala kanye nokukhiqiza kuya ekuqalisweni nasekusekelweni kobuchwepheshe besikhathi eside. Ngokunikeza isethi ephelele yezixazululo ze-hydrogen, kufaka phakathi i-electrolysis yamanzi kanye nokuguqulwa kwe-methanol-to-hydrogen kanye nokuhlanzwa kwe-cog, abahlinzeki bezobuchwepheshe bangasiza amabhizinisi ukuthi ahlele ingxube yawo yamandla ngokusekelwe ezinsizeni zasendaweni ezitholakalayo.

Izifundo zezimboni eziphumelelayo kulo lonke elaseShayina zibonisa ukusebenza kwaleli cebo elihlanganisiwe. Isibonelo, amaqembu amakhulu amakhemikhali asebenzise ngempumelelo amayunithi okuhlanza acubungula amakhulu ezinkulungwane zama-cubic metres egesi ngehora, enikeza izinto zokusetshenziswa zokwenziwa kwe-ammonia noma i-hydrogen ehlanzekile kakhulu yokukhiqiza izinto zikagesi. La maphrojekthi afakazela ukuthi ukuhlanzwa kwe-cog akuyona nje indlela yokuthobela imvelo kodwa inqubo yezimboni eyongeziwe. Uma kuhlanganiswa nezinsizakalo zobungcweti ze-EPC (Ubunjiniyela, Ukuthengwa, kanye Nokwakhiwa) kanye nemiklamo efakwe kuma-skid modular, lobu buchwepheshe bungasetshenziswa ngokushesha, okuvumela izinkampani ukuthi zihlangabezane nezinhloso zazo zokuzinza ngaphakathi kwamafasitela okulawula aqinile.

Ukuhola Indlela Eya Ekusasa Eliqhubekayo Le-Hydrogen

Uhambo oluya emnothweni osekelwe ku-hydrogen ludinga inhlanganisela yolwazi olujulile embonini kanye nocwaningo olusezingeni eliphezulu. I-Ally Hydrogen Energy, inkampani kazwelonke yobuchwepheshe obuphezulu eseChengdu High-Tech Zone, ichithe iminyaka engama-25 ihola phambili kulo mkhankaso. Ngaphambili, eyaziwa ngokuthi i-Ally Hi-Tech, inkampani isiphenduke yaba yiqembu eliholayo embonini yokukhiqiza i-hydrogen yaseShayina, igxile ocwaningweni, ekuthuthukisweni, nasekukhuthazweni kwemakethe kwezixazululo zamandla ezithuthukisiwe. Ngomlando omude wokukhonza izinkampani ezinkulu zomhlaba wonke nezasekhaya ezifana neSinopec, PetroChina, Air Liquide, kanye neLinde, inkampani izisungule njengomhlinzeki ofanelekayo wezinkampani zomhlaba wonke ezisezingeni eliphezulu.

Ngokugxila ekusetshenzisweni okungokoqobo kobuchwepheshe, i-Ally inwebe ukufinyelela kwayo kusukela ekuhlanzweni okuyinhloko kuya kulo lonke uchungechunge lwenani le-hydrogen. Ukuzibophezela kwabo ekhwalithini nasenkonzweni kukhuthaze ubudlelwano besikhathi eside emhlabeni wonke, okuhlanganisa nokusebenzisana ne-Plug Power e-United States kanye ne-Iwatani eJapane. Njengoba umhlaba usondela emigomweni yawo yokungathathi hlangothi kwekhabhoni, indima yabahlinzeki abakhethekile ekuletheni ubuchwepheshe obuqinile, obusebenzayo, nobunwebekayo bokuhlanza ama-cog kuCI-hina iba yinto ebaluleke kakhulu. Ngokuhlaziywa kwamasu kanye nobuchwepheshe obuhle, ukuguquka kusuka emikhiqizweni yezimboni yendabuko kuya kumandla ahlanzekile akuyona nje into engenzeka—kuyiqiniso eliqhubekayo.
