Vhiki imwe mushure mekuburitswa kwehurongwa hweHydrogen yehurumende yeBritain, kuyedza kushandisa 100% hydrogen kugadzira girazi rekuyangarara kwakatangwa munzvimbo yeLiverpool, yaive nguva yekutanga pasirese.
Mafuta emafuta akadai segasi rechisikigo anowanzo shandiswa mukugadzira anozotsiviwa zvachose nehydrogen, izvo zvinoratidza kuti indasitiri yegirazi inogona kuderedza zvakanyanya kuburitsa kabhoni uye kutora danho rakakura kusvika pakuzadzisa chinangwa cheti zero.
Muedzo wakaitwa pafekitari yeSt Helens muPilkington, kambani yegirazi yeBritish, uko kambani yakatanga kutanga kugadzira girazi muna 1826. Kuti iite decarbonize UK, inenge zvikamu zvose zvehupfumi zvinoda kuchinjwa zvachose. Indasitiri inotora 25% yezvese greenhouse gasi emissions muUK, uye kuderedza kuburitswa uku kwakakosha kana nyika ichida kusvika "net zero."
Zvisinei, maindasitiri anoshandisa simba ndiro rimwe rematambudziko akaoma kutarisana nawo. Kuburitswa kwemaindasitiri, sekugadzira magirazi, kwakanyanya kunetsa kuderedza kuburitswa-kuburikidza nekuedza uku, isu tiri nhanho imwe pedyo nekukunda chipingamupinyi ichi. Iyo yepasi inoputsa "HyNet Industrial Fuel Conversion" chirongwa chinotungamirwa neProgressive Energy, uye hydrogen inopiwa neBOC, iyo ichapa HyNet chivimbo mukutsiva gasi rechisikigo nelow-carbon hydrogen.
Uku kunoonekwa sekuratidzwa kukuru kwekutanga pasirese kwe100% kupisa kwehydrogen munzvimbo inoyangarara (sheet) yekugadzira magirazi nharaunda. Muedzo wePilkington kuUnited Kingdom ndechimwe chezvirongwa zvakati kuti zviri kuitika kuchamhembe kwakadziva kumadokero kweEngland kuyedza kuti hydrogen ingatsiva sei mafuta efosi mukugadzira. Gare gare gore rino, mimwe miedzo yeHyNet ichaitwa muPort Sunlight, Unilever.
Aya mapurojekiti ekuratidzira achatsigira pamwe chete shanduko yegirazi, chikafu, chinwiwa, magetsi uye maindasitiri emarara kuti ashandise yakaderera-kabhoni hydrogen kutsiva kushandisa kwavo mafuta efossil. Mayedzo ese ari maviri akashandisa hydrogen yakapihwa neBOC. Muna Kukadzi 2020, BEIS yakapa 5.3 miriyoni pondo mari yeHyNet Industrial Fuel Conversion Project kuburikidza nechirongwa chayo chekuvandudza simba.
“HyNet ichaunza mabasa pamwe nekusimudzira hupfumi kudunhu reNorth West uye kutanga hupfumi husina kabhoni. Isu takatarisana nekuderedza kuburitswa, kuchengetedza 340,000 iripo yekugadzira mabasa mudunhu reNorthwest, uye kugadzira anopfuura zviuru zvitanhatu zvemabasa echigarire. , Kuisa nharaunda munzira yekuva mutungamiriri wepasi rose mukugadzira simba rakachena. "
Matt Buckley, maneja mukuru wekuUK wePilkington UK Ltd., anotsigira NSG Group, akati: "Pilkington naSt Helens vakamira zvakare pamberi pekugadzira maindasitiri uye vakaita bvunzo yekutanga pasirese yehydrogen pamutsetse wekugadzira girazi."
“HyNet richava danho guru rekutsigira mabasa edu ekubvisa carbon. Mushure memavhiki akati wandei ezviyedzo zvakazara zvekugadzira, zvakabudirira kuratidza kuti zvinogoneka kushandisa fekitori yegirazi inoyangarara ine hydrogen zvakachengeteka uye zvinobudirira. Isu tave kutarisira kuti pfungwa yeHyNet iite chokwadi. "
Ikozvino, vagadziri vegirazi vanowanda vari kuwedzera iyo R&D uye hunyanzvi hwekuchengetedza simba uye emission-kudzikisa tekinoroji, uye vanoshandisa tekinoroji nyowani yekunyungudika kudzora mashandisiro esimba rekugadzira magirazi. Mupepeti anonyora matatu kwauri.
1. Oxygen combustion teknolojia
Kupisa kweokisijeni (oxygen combustion) zvinoreva nzira yekutsiva mweya neokisijeni panguva yekupisa mafuta. Iyi tekinoroji inoita inosvika 79% yenitrogen mumhepo isingachatore chikamu mukupisa, izvo zvinogona kuwedzera kupisa kwemoto uye nekumhanyisa kukurumidza kupisa. Pamusoro pezvo, kubuda kwegasi panguva yekupisa kweoxy-mafuta kunenge 25% kusvika 27% yemhepo inopisa, uye mwero wekunyunguduka unovandudzwa zvakanyanya, kusvika 86% kusvika 90%, zvinoreva kuti nzvimbo yevira inodiwa. kuwana chiyero chakafanana chegirazi chinoderedzwa. Diki.
Muna Chikumi 2021, sepurojekiti yakakosha yekutsigira maindasitiri mudunhu reSichuan, Sichuan Kangyu Electronic Technology yakaunza kupedzwa zviri pamutemo kwechirongwa chikuru chembambo yekupisa okisijeni, iyo ine mamiriro ekuchinja moto uye kukwidza tembiricha. Chirongwa chekuvaka ndeche "ultra-thin electronic cover glass substrate, ITO conductive glass substrate", iyo pari zvino ndiyo hombe imwe-yaviri-mutsara weoxygen combustion inoyangarara yemagetsi girazi rekugadzira mutsetse muChina.
Dhipatimendi rekunyungudutsa repurojekiti rinotora oxy-fuel combustion + magetsi ekusimudzira tekinoroji, achivimba neokisijeni uye gasi rinopisa, uye kunyungudika kwekubatsira kuburikidza nekuwedzera kwemagetsi, nezvimwewo, izvo zvisingangogone kuchengetedza 15% kusvika 25% yemafuta ekushandisa, asiwo. wedzera honi Iyo inobuda pachikamu chechikamu chechoto inowedzera kushanda kwekugadzira ne25%. Mukuwedzera, inogonawo kuderedza kubuda kwegasi, kuderedza chikamu cheNOx, CO₂ uye mamwe ma nitrogen oxides anogadzirwa nekupisa neanopfuura 60%, uye kugadzirisa dambudziko rekubuda kwemhepo!
2. Flue gasi denitration teknolojia
Nheyo yeflue gasi denitration tekinoroji ndeye kushandisa oxidant kuoxidize NOX kuNO2, uyezve inogadzirwa NO2 inotorwa nemvura kana alkaline mhinduro kuti iwane dentration. Iyo tekinoroji yakakamurwa zvakanyanya kuita yakasarudzika catalytic kuderedza denitrification (SCR), inosarudza isiri-catalytic kuderedza denitrification (SCNR) uye wet flue gasi denitrification.
Parizvino, maererano nemararamiro ekugadzirisa gasi, makambani egirazi munharaunda yeShahe akanyatsovaka SCR denitration zvivako, achishandisa ammonia, CO kana hydrocarbons seanoderedza vamiririri kuti vaderedze NO mune flue gas kuN2 pamberi peokisijeni.
Hebei Shahe Safety Industrial Co., Ltd. 1-8# girazi muvira flue gasi desulfurization, denitrification uye guruva kubviswa backup mutsara EPC chirongwa. Kubva zvakapedzwa nekushandiswa muna Chivabvu 2017, iyo yekuchengetedzwa kwezvakatipoteredza yanga ichishanda zvakatsiga, uye kuwanda kwezvinosvibisa mugasi reflue zvinogona kusvika zvimedu zvisingasviki 10 mg/N㎡, sulfur dioxide iri pasi pe50 mg/N. ㎡, uye nitrogen oxides isingasviki 100 mg/N㎡, uye zviratidzo zvekusvibisa zvinosvika pachiyero zvakagadzikana kwenguva yakareba.
3. Waste heat power generation technology
Girazi rinonyungudusa choto marara kupisa magetsi kugadzirwa tekinoroji inoshandisa marara kupisa boilers kudzoreredza simba rinopisa kubva mumarara kupisa kwegirazi kunyunguduka mavira kugadzira magetsi. Iyo boiler yemvura yekudyisa inodziya kuti ibudise yakanyanyisa kupisa, uye ipapo iyo inopisa inopisa inotumirwa kune turbine turbine kuti iwedzere uye iite basa, shandura simba remagetsi kuita magetsi emagetsi, uyezve kutyaira jenareta kugadzira magetsi. Iyi tekinoroji haisi kungochengetedza simba chete, asiwo inobatsira kuchengetedzwa kwezvakatipoteredza.
Xianning CSG yakaisa 23 miriyoni yuan mukuvaka kwemarara kupisa magetsi ekugadzira purojekiti muna 2013, uye yakabudirira kubatana kune grid muna Nyamavhuvhu 2014. Mumakore achangopfuura, Xianning CSG yanga ichishandisa tsvina yekupisa magetsi tekinoroji kuti iwane simba rekuchengetedza uye kuderedza emission muindasitiri yegirazi. Zvinonzi avhareji yemagetsi ekugadzira eXianning CSG tsvina yekupisa magetsi chiteshi inosvika mamirioni makumi mana kWh. Chinhu chekushandura chinoverengerwa zvichibva pakushandiswa kwemarasha emagetsi e0.350kg emarasha akajairwa/kWh uye kabhoni dhaibhorosi emission ye2.62kg/kg yemarasha akajairwa. Kugadzirwa kwemagetsi kwakafanana nekuchengetedza 14,000. Matani emarasha akajairika, achideredza kuburitswa kwematani 36,700 ecarbon dioxide!
Chinangwa che "carbon peak" uye "carbon neutrality" inzira yakareba yekuenda. Makambani egirazi achiri kuda kuenderera mberi nekuedza kwavo kusimudzira matekinoroji matsva muindasitiri yegirazi, kugadzirisa chimiro chehunyanzvi, uye kusimudzira kukurumidza kuzadzikiswa kwezvinangwa zvenyika yangu "dual carbon". Ndinotenda kuti pasi pekuvandudzwa kwesainzi uye tekinoroji uye nekurima kwakadzama kwevazhinji vanogadzira magirazi, iyo indasitiri yegirazi ichawana budiriro yemhando yepamusoro, kukura kwegirinhi uye kusimudzira kwakasimba!
