I-ALLY – Itekhnoloji yokuCoca iCOG ePhambili kwixesha elizayo eTshayina: Uhlalutyo oluCwangcisiweyo lokuSusa iCarbonization kwiShishini

Kwimimandla emikhulu yemizi-mveliso emantla eTshayina, iimilo ezinde zezityalo zokupheka bezisoloko ziyimpawu zemveliso yezoqoqosho, kodwa zikwathwala ubunzima bemingeni yokusingqongileyo. Njengoko ubusuku buwela phezu kwendawo eqhelekileyo yokwenziwa kwentsimbi, ukukhanya okuorenji kwee-oven ze-coke kubonisa impikiswano yembali: ukuveliswa okukhulu kweCoke Oven Gas (COG) njengemveliso engasemva. Ngokwembali, uninzi lwale gesi lwaluvutha, nto leyo eyakhokelela ekukhutshweni okukhulu kwekhabhoni, okanye yayisetyenziswa ngokungafanelekanga njengepetroli ephantsi.

Namhlanje, ibali liyatshintsha. Ungxamiseko lwehlabathi lokutshintsha kwamandla luguqule le "nkunkuma yemizi-mveliso" yaba yindawo yobutyebi beqhinga lokuvelisa i-hydrogen. Intliziyo yolu tshintsho ikwimoItekhnoloji yokuCoca iCOG ehamba phambili kwixesha elizayo eTshayina, into entsha ebalulekileyo evala umsantsa phakathi kwemizi-mveliso enzima yendabuko kunye nekamva elingenakhabhoni. Ngokukhupha i-hydrogen ecocekileyo kakhulu kwimixube yegesi eyinkimbinkimbi, le teknoloji ijongana nendawo ebalulekileyo yokuchithwa kwezixhobo kushishino ngelixa ibonelela ngomthombo wamafutha ozinzileyo nowasekuhlaleni kuqoqosho olusakhulayo lwe-hydrogen, ngakumbi kwicandelo lesinyithi kunye neekhemikhali.

Utshintsho lweHlabathi oluya kwi-Industrial Decarbonization kunye neHydrogen Integration

Icandelo lemizi-mveliso lehlabathi ngoku likwindawo ekunzima ukuyifikelela, lihamba kwindlela enzima ukusuka ekuxhomekekeni kwi-fossil-fuel ukuya kwiinkqubo zamandla ezizinzileyo. Izivumelwano zemozulu zamazwe ngamazwe zikhuthaze intshukumo yehlabathi lonke yokususa i-carbonization, kugxilwe kakhulu kumacandelo "anzima ukuwanciphisa" anje ngokwenziwa kwentsimbi, ukuthuthwa kwemithwalo enzima, kunye nokucutshungulwa kweekhemikhali. Kule meko, i-hydrogen ivele njengeyona nto ithwala amandla. IYurophu kunye noMntla Melika zenze inkqubela ebalulekileyo kwi-hydrogen eluhlaza, kodwa umngeni ongxamisekileyo useyindleko kunye nobukhulu bemveliso.

I-China, njengomvelisi omkhulu wehlabathi wentsimbi kunye ne-coke, ikwindawo ekhethekileyo kule ndlela yehlabathi. Iinjongo zikarhulumente waseTshayina ze-"Dual Carbon"—ukufikelela kwinqanaba eliphezulu ekukhutshweni kwekhabhoni ngo-2030 kunye nokufikelela ekungathathi cala kwekhabhoni ngo-2060—zibeke uxinzelelo olukhulu kumashishini emveli ukuba avelise izinto ezintsha. Umzabalazo ophambili weshishini akukuphela nje kokunciphisa ukukhutshwa kwekhabhoni, kodwa ukwenza oko ngendlela ephumelelayo kwezoqoqosho. Ukucocwa kwe-COG kubonelela ngesisombululo esisebenzayo nesinefuthe eliphezulu. Ngokucokisa igesi etyebileyo ye-hydrogen esele iveliswe ngexesha lenkqubo yokucola, amashishini anokunciphisa kakhulu umgama wawo wekhabhoni ngaphandle kokulinda ukuba iziseko ezipheleleyo ze-electrolysis zivuthwe. Olu gxininiso lwasekhaya luhambelana nemizamo yamazwe ngamazwe yokwandisa ukusebenza kakuhle kwezixhobo kwaye lumele isiseko sesiseko sokhuseleko lwamandla eTshayina.

Iingenelo Eziphambili Zokucocwa Kwe-COG Kwindawo Yamandla Yanamhlanje

Inkqubo yokuguqula igesi ye-coke oven eluhlaza ibe yi-hydrogen ekumgangatho we-fuel-cell inzima kakhulu, ifuna ukususwa kokungcola okuntsonkothileyo okufana ne-tar, i-naphthalene, i-ammonia, kunye ne-organic sulfur. Uphuhliso lokucoca i-cog luye lwaya ekusebenzeni okuphezulu kunye nokusetyenziswa kwamandla okuphantsi. Iinkqubo zanamhlanje ngoku zisebenzisa itekhnoloji ye-Pressure Swing Adsorption (PSA) ephucukileyo, evumela ukwahlulwa kwe-hydrogen ngoxinzelelo olwahlukeneyo. Le teknoloji ikhethekileyo yokucoca i-cog kwiCI-hina iphuculwe ukuze ifikelele kumanqanaba obumsulwa angaphezulu kwe-99.999%, ihlangabezana neemfuno ezingqongqo zoshishino lwezithuthi ze-hydrogen fuel cell (HCV).

Enye yeempawu ezibalaseleyo zeenkqubo zamva nje zokucocwa kweengcongolo kukukwazi kwazo ukulungelelanisa izinto eziguquguqukayo zegesi yokutya. Iinkqubo zoshishino azihlali zimile; umgangatho we-COG eluhlaza unokwahluka ngokusekelwe kwiintlobo zamalahle kunye namaqondo obushushu e-oven. Iiyunithi zokucocwa eziphambili ngoku zidibanisa iinkqubo zolawulo ezikrelekrele ezijonga ukungena kwegesi ngexesha langempela, zilungisa imijikelo yokufunxa ukuze kugcinwe umgangatho wokuphuma ohambelanayo. Ngaphezu koko, ukudityaniswa kokucocwa kwamanqanaba amaninzi—kubandakanya unyango lwangaphambi konyango, ukucocwa kakuhle kwe-sulfurization, kunye namanqanaba okugqibela e-PSA—kuqinisekisa ukuba ubomi be-catalyst kunye ne-adsorbent buyandiswa, kunciphisa iindleko zizonke zobunini kubasebenzi bemizi-mveliso. Olu vuthondaba lobuchwephesha ekucocweni kweengcongolo yilo nto evumela ii-mills zentsimbi ezinkulu ukuba zitshintshele kwiindawo zamandla, zibonelela nge-hydrogen ecocekileyo kwiinqanawa zazo ze-logistics okanye kwiimarike zamandla zengingqi.

Uhlalutyo lweSicwangciso: Ukudibanisa iTekhnoloji yokususa iCarbonization eNzulu

Ukususa icarbonization ayisosisombululo semveliso enye kodwa ngumsebenzi obalulekileyo. Ukuze kuchaphazeleke ngokwenene imeko-bume yemizi-mveliso, ukucocwa kweengcongolo kufuneka kujongwe njengenxalenye yenkqubo ebanzi yolawulo lwamandla. Oku akubandakanyi kuphela ukukhutshelwa kwe-hydrogen kodwa kunye nokucinezelwa kwayo, ukugcinwa kwayo, kunye nokusetyenziswa kwayo ekugqibeleni. Indlela ebanzi yenkonzo yemizi-mveliso ibandakanya lonke umjikelo wobomi beprojekthi—ukusuka kuyilo lobunjineli bokuqala kunye nokuveliswa ukuya ekuqaliseni ukusebenza kunye nenkxaso yobugcisa yexesha elide. Ngokunikezela ngesisombululo esipheleleyo se-hydrogen, kubandakanya i-electrolysis yamanzi kunye nokuguqulwa kwe-methanol-to-hydrogen kunye nokucocwa kweengcongolo, ababoneleli ngetekhnoloji banokunceda amashishini ukuba alungelelanise umxube wawo wamandla ngokusekelwe kwizixhobo zasekuhlaleni ezikhoyo.

Izifundo zezemveliso eziphumeleleyo kulo lonke elaseTshayina zibonisa ukusebenza kwesi sicwangciso sidibeneyo. Umzekelo, amaqela amakhulu eekhemikhali asebenzise ngempumelelo iiyunithi zokucoca ezicubungula amakhulu amawaka ee-cubic metres zegesi ngeyure, zibonelela ngezinto eziluhlaza zokwenziwa kwe-ammonia okanye i-hydrogen ecocekileyo kakhulu kwimveliso ye-elektroniki. Ezi projekthi zingqina ukuba ukucocwa kwee-cog akusiyo nje indlela yokuthobela indalo kodwa yinkqubo yemveliso eyongeziweyo. Xa zidityaniswe neenkonzo zobungcali ze-EPC (Ubunjineli, ukuThenga, kunye noKwakha) kunye noyilo olufakwe kwi-skid modular, ezi teknoloji zinokusetyenziswa ngokukhawuleza, zivumela iinkampani ukuba zifezekise iinjongo zazo zozinzo ngaphakathi kwemingcelele eqinileyo yokulawula.

Ukukhokela Indlela Eya Kwikamva Elizinzileyo LeHydrogen

Uhambo oluya kuqoqosho olusekelwe kwi-hydrogen lufuna umxube wamava anzulu kushishino kunye nophando oluphambili. I-Ally Hydrogen Energy, ishishini lesizwe elinobuchwepheshe obuphezulu elikwiChengdu High-Tech Zone, lichithe iminyaka engama-25 likhokela kule ntshukumo. Eyayisaziwa ngokuba yi-Ally Hi-Tech, le nkampani iye yaguquka yaba ligunya eliphambili kushishino lwemveliso ye-hydrogen eTshayina, igxile kuphando, uphuhliso, kunye nokukhuthaza imakethi yezisombululo zamandla eziphambili. Ngembali ende yokukhonza iingxilimbela zamazwe ngamazwe nezasekhaya ezifana neSinopec, iPetroChina, iAir Liquide, kunye neLinde, le nkampani izibonakalise njengomthengisi ofanelekileyo weenkampani zehlabathi ezikumgangatho ophezulu.

Ngokugxila ekusebenziseni ubuchwepheshe ngendlela esebenzayo, i-Ally iye yandisa ukufikelela kwayo ukusuka ekucoceni okungundoqo ukuya kwikhonkco lexabiso le-hydrogen. Ukuzinikela kwabo kumgangatho nakwinkonzo kuye kwakhuthaza ubudlelwane bexesha elide kwihlabathi liphela, kuquka ukusebenzisana ne-Plug Power e-United States kunye ne-Iwatani eJapan. Njengoko ihlabathi lisondela kwiinjongo zalo zokungathathi cala kwekhabhoni, indima yababoneleli abakhethekileyo ekunikezeleni ubuchwepheshe obuqinileyo, obusebenzayo, nobunokwandiswa kuCI-hina ibaluleka ngakumbi. Ngohlalutyo olucwangcisiweyo kunye nokugqwesa kwezobuchwepheshe, utshintsho oluvela kwimveliso yemizi-mveliso yendabuko ukuya kumandla acocekileyo aluyonto enokwenzeka nje kuphela—yinto eyenzekayo.
