Isonto elilodwa ngemva kokukhululwa kwesu likahulumeni waseBrithani le-hydrogen, kwaqalwa ukuhlolwa kokusebenzisa i-hydrogen engu-100% ukukhiqiza ingilazi entantayo endaweni yaseLiverpool, okwakungokokuqala ngqa emhlabeni.
Izibaso ezimbiwa phansi ezifana negesi yemvelo evame ukusetshenziswa enqubweni yokukhiqiza zizothathelwa indawo yi-hydrogen ngokuphelele, okubonisa ukuthi imboni yengilazi inganciphisa kakhulu ukukhishwa kwekhabhoni futhi ithathe isinyathelo esikhulu ekufinyeleleni umgomo we-net zero.
Ukuhlolwa kwenziwa efektri yase-St Helens e-Pilkington, inkampani yengilazi yaseBrithani, lapho inkampani yaqala khona ukukhiqiza ingilazi ngo-1826. Ukuze kukhishwe i-UK, cishe yonke imikhakha yezomnotho idinga ukuguqulwa ngokuphelele.Imboni yenza u-25% wayo yonke intuthu ekhishwa yigesi ebamba ukushisa e-UK, futhi ukunciphisa lokhu kukhishwa kubalulekile uma izwe lizofinyelela "ku-zero."
Nokho, izimboni ezisebenzisa amandla kagesi zingenye yezinselelo ezinzima kakhulu ukubhekana nazo.Ukukhishwa kwezimboni, njengokukhiqiza izingilazi, kunzima kakhulu ukunciphisa ukukhishwa kwegesi-ngalolu cwaningo, siyisinyathelo esisodwa esiseduze sokunqoba lesi sithiyo.Iphrojekthi ye-"HyNet Industrial Fuel Conversion" esezingeni eliphansi iholwa yi-Progressive Energy, kanti i-hydrogen ihlinzekwa yi-BOC, ezonikeza i-HyNet ukuzethemba ekushintsheni igesi yemvelo nge-low-carbon hydrogen.
Lokhu kuthathwa njengombukiso wokuqala omkhulu emhlabeni wokushiswa kwe-hydrogen engu-100% endaweni yokukhiqiza ingilazi entantayo (ishidi).Ukuhlolwa kwe-Pilkington e-United Kingdom kungenye yemiklamo eminingana eqhubekayo enyakatho-ntshonalanga ye-England ukuhlola ukuthi i-hydrogen ingashintsha kanjani amafutha ezinto ezimbiwa phansi lapho kukhiqizwa.Kamuva kulo nyaka, ezinye izivivinyo ze-HyNet zizobanjelwa ePort Sunlight, e-Unilever.
Lezi zinhlelo zemibukiso zizosekela ngokuhlanganyela ukuguqulwa kwezimboni zengilazi, zokudla, iziphuzo, amandla kanye nemfucuza ukuthi zisebenzise i-carbon hydrogen ene-low-carbon esikhundleni sokusebenzisa kwazo izinto zokubasa.Zombili izivivinyo zasebenzisa i-hydrogen ehlinzekwa yi-BOC.NgoFebhuwari 2020, i-BEIS yahlinzeka ngamapondo ayizigidi ezi-5.3 ngezimali ze-HyNet Industrial Fuel Conversion Project ngephrojekthi yayo yokusungula amandla.
“I-HyNet izoletha amathuba omsebenzi kanye nokukhula komnotho esifundeni saseNyakatho-ntshonalanga futhi iqale umnotho wekhabhoni ephansi.Sigxile ekwehliseni ukungcola, ukuvikela imisebenzi yokukhiqiza eyizi-340,000 ekhona esifundeni saseNyakatho-ntshonalanga, nokudala imisebenzi emisha emisha engaphezu kwezi-6,000., Ukubeka isifunda endleleni yokuba umholi womhlaba ekusungulweni kwamandla ahlanzekile.”
UMat Buckley, umphathi jikelele wase-UK we-Pilkington UK Ltd., inkampani engaphansi kwe-NSG Group, uthe: "I-Pilkington ne-St Helens baphinde bama phambili ekusungulweni kwezimboni futhi benza ukuhlolwa kokuqala kwe-hydrogen emgqeni wokukhiqiza ingilazi entantayo."
“I-HyNet izoba yigxathu elikhulu lokweseka imisebenzi yethu yokuqeda ikhabhoni.Ngemva kwamasonto ambalwa okuhlolwa kokukhiqiza okuphelele, kufakazele ngempumelelo ukuthi kungenzeka ukusebenzisa ifekthri yengilazi entantayo ene-hydrogen ngokuphepha nangempumelelo.Manje sibheke ngabomvu ukuthi umqondo we-HyNet ube ngokoqobo. "
Manje, bayanda abakhiqizi bezingilazi bandisa i-R&D kanye nokuqanjwa kabusha kokulondoloza amandla kanye nobuchwepheshe bokunciphisa ukungcola, futhi basebenzisa ubuchwepheshe obusha bokuncibilika ukuze balawule ukusetshenziswa kwamandla okukhiqizwa kwengilazi.Umhleli uzokuklelisa okuthathu.
1. Ubuchwepheshe bokushisa komoyampilo
Ukushiswa komoyampilo kubhekisela enqubweni yokufaka umoya-mpilo esikhundleni somoya ngesikhathi sokushiswa kukaphethiloli.Lobu buchwepheshe benza cishe u-79% we-nitrogen esemoyeni angabe esabamba iqhaza ekushiseni, okungakhuphula izinga lokushisa lomlilo futhi kusheshise isivinini sokuvutha.Ngaphezu kwalokho, ukukhishwa kwegesi ekhishwayo ngesikhathi sokusha kwe-oxy-fuel cishe ku-25% kuya ku-27% wokushisa komoya, futhi izinga lokuncibilika lithuthuke kakhulu, lifinyelela ku-86% kuya ku-90%, okusho ukuthi indawo yesithando somlilo iyadingeka. ukuthola inani elifanayo lengilazi liyancipha.Encane.
NgoJuni 2021, njengomsebenzi obalulekile wokusekela izimboni esifundazweni saseSichuan, i-Sichuan Kangyu Electronic Technology yethula ukuphothulwa ngokusemthethweni kwephrojekthi eyinhloko yehhashi layo le-oxygen evuthayo, elinezimo zokususa umlilo kanye nokunyusa izinga lokushisa.Iphrojekthi yokwakha "i-ultra-thin electronic cover glass substrate, i-ITO conductive glass substrate", okumanje iwumugqa omkhulu wokukhiqiza ingilazi yengilazi ye-oxygen enkulu kunazo zonke enemigqa emibili entantayo e-China.
Umnyango oncibilikayo wephrojekthi wamukela i-oxy-fuel combustion + electric boosting technology, ethembele ekushiseni komoya-mpilo kanye negesi yemvelo, kanye nokuncibilika okusizayo ngokukhushulwa kukagesi, njll., okungagcini nje ukonga u-15% kuya ku-25% wokusetshenziswa kukaphethiloli, kodwa futhi ukwandisa ihhashi Ukukhishwa kwendawo ngayinye yesithando somlilo kwandisa ukusebenza kahle kokukhiqiza cishe ngo-25%.Ngaphezu kwalokho, kungase futhi kunciphise ukukhishwa kwegesi ekhishwayo, kunciphise ingxenye ye-NOx, i-CO₂ namanye ama-nitrogen oxide akhiqizwa ukushiswa okungaphezu kwe-60%, futhi ngokuyisisekelo axazulule inkinga yemithombo yokukhipha!
2. Ubuchwepheshe be-flue gas denitration
Umgomo we-flue gas denitration technology ukusebenzisa i-oxidant ukuze i-oxidize i-NOX ku-NO2, bese i-NO2 ekhiqiziwe imuncwa amanzi noma isisombululo se-alkali ukuze kuzuzwe ukuchazwa.Ubuchwepheshe buhlukaniswe ikakhulukazi i-selective catalytic reduction denitrification (SCR), selective non-catalytic reduction denitrification (SCNR) kanye ne-wet flue gas denitrification.
Njengamanje, mayelana nokwelashwa kwegesi engcolile, izinkampani zezingilazi endaweni yaseShahe ngokuyisisekelo zakha izindawo zokulahla i-SCR, zisebenzisa i-ammonia, i-CO noma ama-hydrocarbons njengama-ejenti okunciphisa ukunciphisa i-NO in flue gas ku-N2 lapho kukhona umoya-mpilo.
I-Hebei Shahe Safety Industrial Co., Ltd. 1-8# i-glass furnace flue gas desulfurization, i-denitrification kanye nomugqa wokusekela wokukhipha uthuli iphrojekthi ye-EPC.Kusukela laqedwa futhi laqala ukusebenza ngoMeyi 2017, uhlelo lokuvikela imvelo belusebenza ngokuzinzile, futhi ukugcwala kokungcola kwegesi ephuma ku-flue kungafinyelela izinhlayiya ezingaphansi kuka-10 mg/N㎡, i-sulphur dioxide ingaphansi kuka-50 mg/N. ㎡, nama-nitrogen oxides angaphansi kuka-100 mg/N㎡, futhi izinkomba zokukhishwa kokungcola zisezingeni elifanele isikhathi eside.
3. Ubuchwepheshe bokukhiqiza amandla okushisa angcolile
Ingilazi encibilika imfucuza yokushisa imfucuza yokukhiqiza amandla ubuchwepheshe obusebenzisa amabhoyela okushisa okulahlwayo ukuze kubuyiselwe amandla ashisayo ekushiseni okulahlwayo kweziko ezincibilikisa ingilazi ukukhiqiza ugesi.Amanzi okuphakela kubhayela ayashiswa ukuze kukhiqizwe isitimu esishisa kakhulu, bese isitimu esishisa kakhulu sithunyelwa enjinini yesitimu ukuze sinwebe futhi senze umsebenzi, siguqule amandla kagesi sibe amandla emishini, bese sishayela ijeneretha ukuze ikhiqize ugesi.Lobu buchwepheshe abugcini nje kuphela ukonga amandla, kodwa futhi buhambisana nokuvikelwa kwemvelo.
I-Xianning CSG yatshala ama-yuan ayizigidi ezingu-23 ekwakhiweni kwephrojekthi yokukhiqiza amandla okushisa imfucuza ngo-2013, futhi yaxhunywa ngempumelelo kugridi ngo-August 2014. Eminyakeni yamuva nje, i-Xianning CSG ibisebenzisa ubuchwepheshe bokukhiqiza amandla okushisa imfucuza ukuze kuzuzwe ukonga amandla kanye ukunciphisa ukungcola embonini yengilazi.Kubikwa ukuthi isilinganiso samandla esiphehla ugesi sesiteshi sikagesi se-Xianning CSG silinganiselwa ku-40 million kWh.Isici sokuguqula sibalwa ngokususela ekusetshenzisweni kwamalahle okujwayelekile kokukhiqiza amandla angu-0.350kg welahle elijwayelekile/kWh kanye nokuphuma kwe-carbon dioxide okungu-2.62kg/kg kwamalahle ajwayelekile.Ukukhiqizwa kukagesi kulingana nokonga i-14,000.Amathani amalahle ajwayelekile, anciphisa ukukhishwa kwamathani angu-36,700 esikhutha!
Umgomo "we-carbon peak" kanye "ne-carbon neutrality" iyindlela ende okufanele yenziwe.Izinkampani zengilazi zisadinga ukuqhubeka nemizamo yazo yokuthuthukisa ubuchwepheshe obusha embonini yengilazi, zilungise ukwakheka kwezobuchwepheshe, futhi zikhuthaze ukufezeka ngokushesha kwezinjongo zezwe lami “ezimbaxambili zekhabhoni”.Ngikholelwa ukuthi ngaphansi kokuthuthukiswa kwesayensi nobuchwepheshe kanye nokutshala okujulile kwabakhiqizi abaningi bezingilazi, imboni yengilazi ngokuqinisekile izozuza ukuthuthukiswa kwekhwalithi ephezulu, ukuthuthukiswa okuluhlaza kanye nentuthuko eqhubekayo!
