Patangotha sabata imodzi kutulutsidwa kwa njira ya hydrogen ya boma la Britain, kuyesa kugwiritsa ntchito 100% haidrojeni kupanga magalasi oyandama kudayambika mdera la Liverpool, lomwe linali koyamba padziko lapansi.
Mafuta amafuta monga gasi wachilengedwe omwe amagwiritsidwa ntchito nthawi zambiri popanga adzasinthidwa ndi haidrojeni, zomwe zikuwonetsa kuti makampani opanga magalasi amatha kuchepetsa kwambiri mpweya wa kaboni ndikutenga gawo lalikulu pakukwaniritsa cholinga cha net zero.
Kuyesedwa kunachitika ku fakitale ya St Helens ku Pilkington, kampani ya magalasi ya ku Britain, kumene kampaniyo inayamba kupanga galasi mu 1826. Kuti awononge dziko la UK, pafupifupi magawo onse azachuma ayenera kusinthidwa kwathunthu.Makampani amatenga 25% ya mpweya wowonjezera kutentha ku UK, ndipo kuchepetsa mpweya woipawu ndikofunikira ngati dzikolo lifike "ziro".
Komabe, mafakitale omwe amagwiritsa ntchito mphamvu zamagetsi ndi chimodzi mwazovuta kwambiri kuthana nazo.Kutulutsa kwa mafakitale, monga kupanga magalasi, kumakhala kovuta kwambiri kuchepetsa mpweya-kupyolera mukuyesera uku, ndife sitepe imodzi yoyandikira kuthana ndi chopingachi.Ntchito yovuta kwambiri ya "HyNet Industrial Fuel Conversion" ikutsogoleredwa ndi Progressive Energy, ndipo hydrogen imaperekedwa ndi BOC, yomwe idzapatsa HyNet chidaliro m'malo mwa gasi wachilengedwe ndi carbon hydrogen yochepa.
Ichi ndi chionetsero choyamba chachikulu padziko lonse lapansi cha 100% kuyaka kwa haidrojeni pamalo opangira magalasi oyandama (mapepala).Mayeso a Pilkington ku United Kingdom ndi amodzi mwa ntchito zingapo zomwe zikuchitika kumpoto chakumadzulo kwa England kuyesa momwe haidrojeni ingalowe m'malo mwamafuta opangira zinthu zakale.Pambuyo pake chaka chino, kuyesa kwina kwa HyNet kudzachitika ku Port Sunlight, Unilever.
Ntchito zowonetsera izi zithandizira kusinthika kwa mafakitale agalasi, chakudya, zakumwa, mphamvu ndi zinyalala kuti agwiritse ntchito mpweya wochepa wa hydrogen kuti alowe m'malo mwawo kugwiritsa ntchito mafuta oyaka.Mayesero onsewa adagwiritsa ntchito haidrojeni yoperekedwa ndi BOC.Mu February 2020, BEIS idapereka ndalama zokwana mapaundi 5.3 miliyoni za HyNet Industrial Fuel Conversion Project kudzera mu projekiti yake yopangira mphamvu.
"HyNet idzabweretsa ntchito ndi kukula kwachuma kudera la Kumpoto chakumadzulo ndikuyambitsa chuma chochepa cha carbon.Timayang'ana kwambiri kuchepetsa kutulutsa mpweya, kuteteza ntchito zopanga 340,000 zomwe zilipo kale m'chigawo cha kumpoto chakumadzulo, ndikupanga ntchito zatsopano zopitilira 6,000., Kuyika derali panjira yoti likhale mtsogoleri wapadziko lonse pakupanga zatsopano zamagetsi.
Matt Buckley, manejala wamkulu wa Pilkington UK Ltd., wothandizidwa ndi NSG Group, adati: "Pilkington ndi St Helens adayimiliranso patsogolo pazatsopano zamafakitale ndikuyesa kuyesa kwa haidrojeni padziko lonse lapansi pamzere wopangira magalasi oyandama."
"HyNet ikhala gawo lalikulu lothandizira ntchito zathu za decarbonization.Pambuyo pa masabata angapo a kuyesa kwathunthu, zatsimikizira bwino kuti ndizotheka kugwiritsa ntchito fakitale yoyandama yamagalasi ndi haidrojeni mosamala komanso moyenera.Tsopano tikuyembekezera kuti lingaliro la HyNet likwaniritsidwe. ”
Tsopano, opanga magalasi ochulukirachulukira akuwonjezera R&D ndi luso laukadaulo wopulumutsa mphamvu komanso kuchepetsa utsi, ndikugwiritsa ntchito ukadaulo watsopano wosungunuka kuti azitha kuwongolera mphamvu zopangira magalasi.Mkonzi akulemberani atatu.
1. Ukadaulo wakuyaka kwa okosijeni
Kuyaka kwa okosijeni kumatanthauza njira yosinthira mpweya ndi mpweya mkati mwa kuyaka kwamafuta.Ukadaulo uwu umapangitsa pafupifupi 79% ya nayitrogeni mumlengalenga satenga nawo gawo pakuwotcha, zomwe zimatha kuwonjezera kutentha kwa lawi ndikufulumizitsa kuyaka.Kuphatikiza apo, mpweya wotulutsa mpweya pa kuyaka kwamafuta oxy-mafuta ndi pafupifupi 25% mpaka 27% ya kuyaka kwa mpweya, komanso kusungunuka kwake kumakulanso bwino, kufika 86% mpaka 90%, zomwe zikutanthauza kuti malo a ng'anjo amafunikira. kupeza magalasi omwewo amachepetsedwa.Wamng'ono.
Mu June 2021, monga pulojekiti yayikulu yothandizira mafakitale m'chigawo cha Sichuan, Sichuan Kangyu Electronic Technology inayambitsa kutsirizitsa ntchito yaikulu ya ng'anjo yake yonse ya okosijeni, yomwe ili ndi zofunikira zosinthira moto ndi kukweza kutentha.Ntchito yomangayi ndi "gawo lagalasi lagalasi lopyapyala kwambiri, ITO conductive glass substrate", yomwe pakadali pano ndi njira yayikulu kwambiri yopangira magalasi amagetsi amagetsi amizere iwiri ya okosijeni ku China.
Dipatimenti yosungunula polojekitiyi imagwiritsa ntchito ukadaulo wa oxy-fuel combustion + wowonjezera mphamvu zamagetsi, kudalira kuyaka kwa okosijeni ndi gasi, komanso kusungunula kothandizira kudzera pakuwonjezera magetsi, ndi zina, zomwe sizingapulumutse 15% mpaka 25% yamafuta, komanso onjezani ng'anjo Zomwe zimatuluka pagawo lililonse la ng'anjo zimawonjezera kupanga bwino ndi 25%.Kuphatikiza apo, itha kuchepetsanso mpweya wotulutsa mpweya, kuchepetsa kuchuluka kwa NOx, CO₂ ndi ma nitrogen oxides ena opangidwa ndi kuyaka ndi kupitilira 60%, ndikuthetsa vuto la magwero a mpweya!
2. Ukadaulo wotsutsa gasi wa flue
Mfundo yaukadaulo wotsitsa mpweya wa flue ndikugwiritsa ntchito oxidant kuti oxidize NOX kupita ku NO2, kenako NO2 yopangidwa imatengedwa ndi madzi kapena alkaline yankho kuti ikwaniritse denitration.Ukadaulowu umagawika m'magulu osankha othandizira kuchepetsa denitrification (SCR), selective non-catalytic reduction denitrification (SCNR) ndi wet flue gas denitrification.
Pakalipano, ponena za chithandizo cha gasi wa zinyalala, makampani agalasi m'dera la Shahe adamanga malo owonetsera SCR, pogwiritsa ntchito ammonia, CO kapena ma hydrocarbons monga othandizira kuchepetsa NO mu mpweya wa flue ku N2 pamaso pa mpweya.
Hebei Shahe Safety Industrial Co., Ltd. 1-8# galasi ng'anjo flue mpweya desulfurization, denitrification ndi kuchotsa fumbi zosunga zobwezeretsera mzere EPC polojekiti.Popeza unamalizidwa ndi kuikidwa mu May 2017, dongosolo chitetezo zachilengedwe wakhala akugwira ntchito mokhazikika, ndi ndende ya zoipitsa mpweya chitoliro akhoza kufika particles zosakwana 10 mg/N㎡, sulfure dioxide ndi zosakwana 50 mg/N ㎡, ndipo ma nitrogen oxides ndi ochepera 100 mg/N㎡, ndipo zisonyezo zotulutsa zowononga zimakhala zokhazikika kwa nthawi yayitali.
3. Zinyalala kutentha kutentha mphamvu luso
Galasi yosungunula ng'anjo yotentha yamagetsi ndi ukadaulo womwe umagwiritsa ntchito ma boiler otentha zinyalala kuti apezenso mphamvu zowotcha kuchokera pakuwotcha kowonongeka kwa ng'anjo zosungunuka zamagalasi kuti apange magetsi.Madzi opangira boiler amatenthedwa kuti apange nthunzi yotentha kwambiri, kenako nthunzi yotentha kwambiri imatumizidwa ku turbine ya nthunzi kuti ikulitsidwe ndikugwira ntchito, kusintha mphamvu zamagetsi kukhala mphamvu zamakina, kenako ndikuyendetsa jenereta kuti ipange magetsi.Ukadaulo uwu sikuti umangopulumutsa mphamvu, komanso umathandizira kuteteza chilengedwe.
Xianning CSG adayika ndalama zokwana 23 miliyoni za yuan pomanga ntchito yopangira mphamvu zowononga kutentha mu 2013, ndipo idalumikizidwa bwino ndi gululi mu Ogasiti 2014. M'zaka zaposachedwa, Xianning CSG yakhala ikugwiritsa ntchito luso lamagetsi lotayirira kuti likwaniritse zopulumutsa mphamvu komanso kuchepetsa umuna mumakampani agalasi.Akuti mphamvu yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi ya Xianning CSG ndi pafupifupi 40 miliyoni kWh.Kutembenuka kumawerengeredwa potengera momwe malasha amagwiritsidwira ntchito popanga mphamvu ya 0.350kg ya malasha wokhazikika/kWh ndi mpweya woipa wa 2.62kg/kg wa malasha wamba.Kupanga magetsi ndikofanana ndi kupulumutsa 14,000.Matani a malasha wamba, kuchepetsa mpweya woipa wa matani 36,700 a carbon dioxide!
Cholinga cha "carbon peak" ndi "carbon neutrality" ndi njira yayitali yopitira.Makampani agalasi akufunikabe kupitiliza kuyesetsa kwawo kukweza umisiri watsopano mumakampani agalasi, kusintha mawonekedwe aukadaulo, ndikulimbikitsa kukwaniritsidwa kofulumira kwa zolinga zadziko langa za "carbon wapawiri".Ndikukhulupirira kuti pansi pa chitukuko cha sayansi ndi zamakono komanso kulima mozama kwa opanga magalasi ambiri, makampani a galasi adzakwaniritsa chitukuko chapamwamba, chitukuko chobiriwira ndi chitukuko chokhazikika!
