Kwiveki enye emva kokukhululwa kweqhinga likarhulumente waseBhritane lehydrogen, ilingo lokusebenzisa i-100% yehydrogen ukuvelisa iglasi edadayo laqaliswa kummandla weLiverpool, eyayikokokuqala ngqa emhlabeni.
Amafutha efosili afana nerhasi yendalo edla ngokusetyenziswa kwinkqubo yokuvelisa aya kutshintshwa ngokupheleleyo yihydrogen, nto leyo ebonisa ukuba ishishini leglasi linokunciphisa kakhulu ukukhutshwa kwekhabhoni kwaye lithathe inyathelo elikhulu ekufezekiseni injongo ye-net zero.
Uvavanyo lwenziwa kwifektri yaseSt Helens ePilkington, inkampani yeglasi yaseBrithani, apho inkampani yaqala ukuvelisa iglasi ngo-1826. Ukuze i-decarbonize yase-UK, phantse onke amacandelo ezoqoqosho kufuneka aguqulwe ngokupheleleyo.Umzi-mveliso uthatha i-25% yazo zonke izinto ezikhutshwa yi-greenhouse gas e-UK, kwaye ukunciphisa oku kukhutshwayo kubalulekile ukuba ilizwe lifikelele kwi-"net zero."
Nangona kunjalo, amashishini asebenzisa amandla amaninzi ngomnye wemingeni enzima kakhulu ukujongana nayo.Ukukhutshwa kwemizi-mveliso, okufana nokuveliswa kweglasi, kunzima kakhulu ukunciphisa ukukhutshwa kwezinto ezikhutshwayo-ngolu vavanyo, silinyathelo elinye elikufutshane lokoyisa lo mqobo.Iprojekthi ye-"HyNet Industrial Fuel Conversion" ehamba phambili ikhokelwa yi-Progressive Energy, kwaye i-hydrogen inikezelwa yi-BOC, eya kunika i-HyNet ngokuzithemba ekutshintsheni igesi yendalo kunye ne-carbon hydrogen ephantsi.
Oku kuthathwa njengomboniso omkhulu wokuqala wehlabathi we-100% yokutsha kwehydrogen kwindawo yokuvelisa iglasi edadayo (iphepha).Uvavanyo lwePilkington e-United Kingdom yenye yeeprojekthi ezininzi eziqhubekayo kumntla-ntshona weNgilani ukuvavanya ukuba i-hydrogen inokutshintsha njani i-fuel fuels kwimveliso.Kamva kulo nyaka, amanye amalingo e-HyNet aya kubanjelwa ePort Sunlight, e-Unilever.
Ezi projekthi zokubonisa ziya kuxhasa ngokubambisana ukuguqulwa kweglasi, ukutya, isiselo, amandla kunye nemizi-mveliso yenkunkuma ekusebenziseni i-carbon hydrogen ephantsi ukuze ithathe indawo yokusetyenziswa kwamafutha efosili.Zombini izilingo zisebenzisa i-hydrogen ebonelelwa yi-BOC.NgoFebruwari ka-2020, i-BEIS ibonelele nge-5.3 yezigidi zeeponti kwinkxaso-mali ye-HyNet Industrial Fuel Conversion Project ngeprojekthi yayo yokuvelisa amandla.
“I-HyNet iza kuzisa ingqesho kunye nokukhula koqoqosho kummandla waseMntla-ntshona kwaye iqalise uqoqosho lwekhabhoni ephantsi.Sigxile ekunciphiseni ukukhutshwa kwezinto ezikhutshwayo, ukukhusela imisebenzi ekhoyo yemveliso engama-340,000 kwingingqi yoMntla-ntshona, nokudala imisebenzi esisigxina engaphezu kwama-6,000., Ukubeka ummandla kwindlela yokuba yinkokeli yehlabathi ekutshatyalalisweni kwamandla acocekileyo. "
UMat Buckley, umanejala jikelele wase-UK we-Pilkington UK Ltd., i-subsidiary ye-NSG Group, uthe: "I-Pilkington kunye ne-St Helens baphinde bema ngaphambili kuphuhliso lwemizi-mveliso kwaye baqhuba uvavanyo lokuqala lwe-hydrogen kumgca wokuvelisa iglasi edadayo."
“I-HyNet iya kuba linyathelo elikhulu lokuxhasa imisebenzi yethu yokususa ikhabhon.Emva kweeveki ezininzi zolingo olupheleleyo lwemveliso, ingqine ngempumelelo ukuba kuyenzeka ukusebenzisa umzi-mveliso weglasi edadayo ngehydrogen ngokukhuselekileyo nangempumelelo.Ngoku sijonge phambili kumbono weHyNet ukuba ube yinyani. ”
Ngoku, ngakumbi nangakumbi abavelisi beglasi banyusa i-R&D kunye nokuveliswa kwetekhnoloji yokonga amandla kunye nokunciphisa ukukhutshwa, kwaye basebenzise itekhnoloji entsha yokunyibilikisa ukulawula ukusetyenziswa kwamandla kwimveliso yeglasi.Umhleli uyakudwelisa ezithathu.
1. Iteknoloji yokutshisa i-oksijeni
Ukutsha kweoksijini kubhekiselele kwinkqubo yokutshintsha umoya ngeoksijini kwinkqubo yokutshiswa kwamafutha.Le teknoloji yenza malunga ne-79% ye-nitrogen emoyeni ayisekho inxaxheba ekutshisweni, oko kunokunyusa ubushushu bomlilo kunye nokukhawuleza isantya sokutsha.Ukongeza, ukukhutshwa kwegesi ephumayo ngexesha lokutsha kwe-oxy-fuel malunga ne-25% ukuya kwi-27% yokutsha komoya, kwaye izinga lokunyibilika liphuculwe kakhulu, lifikelela kwi-86% ukuya kwi-90%, okuthetha ukuba indawo yeziko iyadingeka. ukufumana isixa esifanayo seglasi sincitshisiwe.Incinci.
NgoJuni 2021, njengeprojekthi yenkxaso yeshishini eliphambili kwiPhondo laseSichuan, iSichuan Kangyu Electronic Technology yazisa ukugqitywa ngokusemthethweni kweprojekthi ephambili ye-oksijini yokutshisa i-oxygen yonke, enemiqathango yokutshintsha umlilo kunye nokunyusa ubushushu.Iprojekthi yolwakhiwo "yi-ultra-thin electronic cover glass substrate, i-ITO conductive glass substrate", ekungokunje iyeyona inkulu ye-kiln ene-oxygen combustion line line yokuvelisa iglasi yombane eTshayina.
Isebe elinyibilikayo leprojekthi lithatha i-oxy-fuel combustion + iteknoloji yokunyusa amandla ombane, ixhomekeke kwi-oksijini kunye nokutsha kwegesi yendalo, kunye nokunyibilika okuncedisayo ngokunyusa umbane, njl. ukwandisa i-kilni Imveliso kwindawo nganye yeyunithi yesithando somlilo inyusa ukusebenza kakuhle kwemveliso malunga ne-25%.Ukongeza, kunokunciphisa ukukhutshwa kwegesi ephumayo, ukunciphisa umlinganiselo we-NOx, i-CO₂ kunye nezinye i-nitrogen oxides eziveliswa ngokutshiswa ngaphezu kwe-60%, kwaye ngokusisiseko ukusombulula ingxaki yemithombo yokukhutshwa!
2. Itekhnoloji yokunqanda igesi yomkhuhlane
Umgaqo wobuchwephesha be-flue gas denitration kukusebenzisa i-oxidant kwi-oxidize i-NOX kwi-NO2, kwaye ke i-NO2 eveliswayo ifunxwa ngamanzi okanye isisombululo se-alkali ukufezekisa i-denitration.Itekhnoloji yahlulahlulwe ikakhulu kwi-selective catalytic reduction denitrification (SCR), i-elective non-catalytic reduction denitrification (SCNR) kunye ne-wet flue gas denitrification.
Okwangoku, ngokubhekiselele kunyango lwegesi yenkunkuma, iinkampani zeglasi kwindawo yaseShahe ziye zakha ngokusisiseko izibonelelo ze-SCR denitration, zisebenzisa i-ammonia, i-CO okanye i-hydrocarbons njenge-agent zokunciphisa ukunciphisa i-NO kwi-flue gas kwi-N2 phambi kwe-oksijeni.
Hebei Shahe Safety Industrial Co., Ltd. 1-8# iglasi eziko flue gas desulfurization, denitrification kunye nothuli ukususwa umgca backup umgca EPC project.Ekubeni igqitywe kwaye isetyenziswe ngoMeyi 2017, inkqubo yokukhusela indalo iye yasebenza ngokuzinzileyo, kwaye ukuxinwa kwezinto ezingcolileyo kwi-flue gas kunokufikelela kumasuntswana angaphantsi kwe-10 mg / N㎡, i-sulphur dioxide ingaphantsi kwe-50 mg / N. ㎡, kunye neeoksijini zenitrogen zingaphantsi kwe-100 mg/N㎡, kwaye izalathisi zokukhutshwa kongcoliseko zikumgangatho ozinzileyo ixesha elide.
3. Inkunkuma yokuvelisa amandla obushushu iteknoloji
Iziko lokunyibilika kweglasi yenkunkuma yokuvelisa amandla obushushu bubuchwepheshe obusebenzisa iibhoyila zobushushu obusetyenzisiweyo ukubuyisela amandla ashushu kubushushu obuyinkunkuma beeglasi ezinyibilikisayo ukuvelisa umbane.Ibhoyila yamanzi esondlo iyafudunyezwa ukuze ivelise umphunga oshushu kakhulu, emva koko umphunga oshushu kakhulu uthunyelwe kwi-injini yomphunga ukuze wandise kwaye wenze umsebenzi, uguqule amandla ombane abe ngamandla oomatshini, emva koko uqhube ijenereyitha ukuvelisa umbane.Le teknoloji ayigcini nje ukugcina amandla, kodwa iphinda incede ukukhuselwa kwendalo.
I-Xianning CSG ityale izigidi ezingama-23 zeeyuan kulwakhiwo lweprojekthi yokuvelisa amandla obushushu ngo-2013, kwaye yaqhagamshelwa ngempumelelo kwigridi ngo-Agasti 2014. Kwiminyaka yakutshanje, i-Xianning CSG ibisebenzisa itekhnoloji yokuvelisa amandla obushushu ukuphumeza ukonga amandla kunye ukunciphisa ukukhutshwa kwemveliso yeglasi.Kuxelwe ukuba umndilili wokuveliswa kombane kwisikhululo samandla senkunkuma yenkunkuma iXianning CSG imalunga nezigidi ezingama-40 kWh.Umba woguqulo ubalwa ngokusekwe kusetyenziso olusemgangathweni lwamalahle okuvelisa amandla e-0.350kg yamalahle aqhelekileyo/kWh kunye nokukhutshwa kwekharbon diokside ye-2.62kg/kg yamalahle aqhelekileyo.Ukuveliswa kwamandla kulingana nokugcina i-14,000.Iitoni zamalahle aqhelekileyo, anciphisa ukukhutshwa kweetoni ezingama-36,700 zecarbon dioxide!
Injongo ye "carbon peak" kunye "ne-carbon neutrality" yindlela ende yokuhamba.Iinkampani zeglasi zisafuna ukuqhubeka neenzame zazo zokuphucula itekhnoloji entsha kushishino lweglasi, ukulungelelanisa ubume bobugcisa, kunye nokukhuthaza ukufezekiswa okukhawulezileyo kweenjongo zelizwe lam “zekhabhoni ezimbini”.Ndiyakholelwa ukuba phantsi kophuhliso lwesayensi kunye nobuchwepheshe kunye nokulima okunzulu kwabaninzi abavelisi beglasi, ishishini leglasi liya kufezekisa uphuhliso oluphezulu, uphuhliso oluluhlaza kunye nophuhliso oluzinzileyo!
