Beke ka mor'a ho lokolloa ha leano la 'muso oa Brithani oa hydrogen, teko ea ho sebelisa 100% hydrogen ho hlahisa likhalase tse phaphametseng e ile ea qalisoa sebakeng sa Liverpool, seo e neng e le lekhetlo la pele lefatšeng.
Lifuso tsa khale tse kang khase ea tlhaho e atisang ho sebelisoa ha ho etsoa tlhahiso li tla nkeloa sebaka ka ho feletseng ke hydrogen, e leng se bontšang hore indasteri ea likhalase e ka fokotsa haholo mocheso oa carbon le ho nka mohato o moholo oa ho finyella sepheo sa net zero.
Teko e ile ea etsoa fekthering ea St Helens e Pilkington, k'hamphani ea khalase ea Brithani, moo k'hamphani e qalileng ho etsa likhalase ka 1826. E le ho senya UK, hoo e batlang e le likarolo tsohle tsa moruo li hloka ho fetoloa ka ho feletseng. Indasteri e etsa karolo ea 25% ea likhase tsohle tse hlahisoang ke greenhouse UK, 'me ho fokotsa likhase tsena ho bohlokoa haeba naha e batla ho fihla ho "notho".
Leha ho le joalo, liindasteri tse hlokang matla ke tse ling tsa liqholotso tse thata ho sebetsana le tsona. Mesi ea liindasteri, joalo ka tlhahiso ea likhalase, e thata haholo ho fokotsa mesi-ka teko ena, re mohato o le mong o haufi oa ho hlola tšitiso ena. Morero o matla oa "HyNet Industrial Fuel Conversion" o etelletsoe pele ke Progressive Energy, 'me hydrogen e fanoa ke BOC, e tla fa HyNet kholiseho ea ho nkela khase ea tlhaho sebaka ka carbon hydrogen e tlaase.
Ena e nkoa e le pontšo ea pele e kholo ea lefats'e ea 100% ea ho tuka ha hydrogen tikolohong ea tlhahiso ea likhalase tse phaphametseng (lakane). Teko ea Pilkington United Kingdom ke e 'ngoe ea merero e' maloa e ntseng e tsoela pele ka leboea-bophirima ho Engelane ho leka hore na haedrojene e ka nka sebaka sa mafura a khale joang tlhahisong. Hamorao selemong sena, liteko tse ling tsa HyNet li tla tšoareloa Port Sunlight, Unilever.
Merero ena ea lipontšo e tla ts'ehetsa ka kopanelo phetoho ea liindasteri tsa likhalase, lijo, lino, matla le litšila ho sebelisoa ha hydrogen e nang le khabone e tlase ho nka sebaka sa ts'ebeliso ea tsona ea mafura a khale. Liteko ka bobeli li sebelisitse hydrogen e fanoeng ke BOC. Ka Hlakola 2020, BEIS e ile ea fana ka liponto tse limilione tse 5.3 ka lichelete bakeng sa Morero oa Phetoho ea Mafura a HyNet Industrial ka projeke ea eona ea ntlafatso ea matla.
“HyNet e tla tlisa mesebetsi le kgolo ya moruo sebakeng sa Leboya Bophirima le ho qala moruo wa khabone e tlase. Re tsepamisitse maikutlo ho fokotseng mesi, ho sireletsa mesebetsi e 340 000 e teng ya tlhahiso sebakeng sa Leboya Bophirima, le ho thea mesebetsi e metjha e fetang 6 000 ya leruri. , Ho beha sebaka tseleng ea ho ba moetapele oa lefats'e oa boqapi bo hloekileng ba matla.
Matt Buckley, molaoli kakaretso oa UK oa Pilkington UK Ltd., e leng setsi sa NSG Group, o itse: "Pilkington le St Helens ba ile ba boela ba ema ka pele ho boqapi ba indasteri mme ba etsa tlhahlobo ea pele ea hydrogen moleng oa tlhahiso ea likhalase tse phaphametseng."
"HyNet e tla ba mohato o moholo oa ho ts'ehetsa mesebetsi ea rona ea ho tlosa khabone. Ka mor'a libeke tse 'maloa tsa liteko tse feletseng tsa tlhahiso, e ipakile ka katleho hore hoa khoneha ho sebetsa fektheri ea khalase e phaphametseng ka hydrogen ka mokhoa o sireletsehileng le ka katleho. Hona joale re lebelletse hore mohopolo oa HyNet o tla phethahala. ”
Hona joale, baetsi ba likhalase ba ntseng ba eketseha ba ntse ba eketsa R&D le boqapi ba theknoloji ea ho boloka matla le ho fokotsa mosi, 'me ba sebelisa theknoloji e ncha ea ho qhibiliha ho laola tšebeliso ea matla ea tlhahiso ea likhalase. Mohlophisi o tla u ngolla tse tharo.
1. Theknoloji ea ho chesa oksijene
Ho chesa oksijene ho bolela mokhoa oa ho nkela moea sebaka ka oksijene nakong ea ho tuka ha mafura. Theknoloji ena e etsa hore hoo e ka bang 79% ea naetrojene moeeng ha e sa kenya letsoho ho tukang, e leng se ka eketsang mocheso oa lelakabe le ho potlakisa lebelo la ho tuka. Ntle le moo, tlhahiso ea khase e tsoang nakong ea mollo oa oxy-fuel e ka ba 25% ho isa ho 27% ea moea o tukang, mme sekhahla sa ho qhibiliha le sona se ntlafalitsoe haholo, se fihla ho 86% ho isa ho 90%, ho bolelang hore sebaka sa sebōpi se hlokahalang. ho fumana bokaalo ba khalase bo fokotsehile. Nyenyane.
Ka Phuptjane 2021, joalo ka projeke ea mantlha ea ts'ehetso ea indasteri Profinseng ea Sichuan, Sichuan Kangyu Electronic Technology e ile ea kenya letsoho ho phetheloa ka molao morero oa mantlha oa sebōpi sa eona sa mollo o tukang oksijene, eo ha e le hantle e nang le maemo a ho fetola mollo le ho phahamisa mocheso. Morero oa kaho ke "ultra-thin electronic cover glass substrate, ITO conductive glass substrate", eo hajoale e leng eona e kholo ka ho fetisisa e nang le mela e 'meli ea ho chesa oksijene e hlahisang likhalase tsa elektroniki Chaena.
Lefapha la ho qhibiliha la morero le amohela theknoloji ea ho chesa oxy-fuel + ho matlafatsa theknoloji ea motlakase, ho itšetlehile ka ho chesa oksijene le khase ea tlhaho, le ho qhibiliha ho thusang ka ho matlafatsa motlakase, joalo-joalo, e ke keng ea boloka 15% ho 25% feela ea tšebeliso ea mafura, empa hape eketsa sebōpi Se hlahisoang sebakeng se seng le se seng sa sebōpi se eketsa katleho ea tlhahiso ka hoo e ka bang 25%. Ho phaella moo, e ka boela ea fokotsa mocheso oa khase ea ho qeta, ea fokotsa karolo ea NOx, CO₂ le li-oxide tse ling tsa naetrojene tse hlahisoang ke mollo ka ho feta 60%, 'me ha e le hantle ho rarolla bothata ba mehloli ea tlhahiso!
2. Theknoloji ea ho thibela khase ea flue
Molao-motheo oa theknoloji ea ho thibela khase ea flue ke ho sebelisa oxidant ho oxidize NOX ho NO2, ebe NO2 e hlahisoang e kenngoa ke metsi kapa tharollo ea alkaline ho finyella denitration. Theknoloji e arotsoe haholo-holo ka "Selective Catalytic Reduction denitrification" (SCR), selective non-catalytic reduction denitrification (SCNR) le wet flue gas denitrification.
Hona joale, mabapi le phekolo ea khase ea litšila, lik'hamphani tsa khalase sebakeng sa Shahe ha e le hantle li hahile lisebelisoa tsa SCR denitration, li sebelisa ammonia, CO kapa li-hydrocarbon e le lisebelisoa tse fokotsang ho fokotsa NO ka khase ea flue ho N2 ka boteng ba oksijene.
Hebei Shahe Safety Industrial Co., Ltd. 1-8# glass furnace flue gas desulfurization, denitrification le lerōle ho tloswa bekapo line line EPC morero. Ho tloha ha e phetheloa le ho kengoa tšebetsong ka Mots'eanong 2017, sistimi ea ts'ireletso ea tikoloho e ntse e sebetsa ka mokhoa o tsitsitseng, mme bongata ba litšila tse ka har'a khase ea flue bo ka fihla likaroloana tse ka tlase ho 10 mg/N㎡, sulfur dioxide e ka tlase ho 50 mg/N ㎡, 'me nitrogen oxides e ka tlase ho 100 mg/N㎡, 'me matšoao a tlhahiso ea tšilafalo a maemong a tsitsitseng ka nako e telele.
3. Theknoloji ea ho hlahisa matla a mocheso oa litšila
Khalase e qhibilihisang litšila tsa mocheso oa mocheso oa likhalase ke theknoloji e sebelisang li-boilers tsa mocheso oa litšila ho khutlisa matla a mocheso mochesong oa litšila oa libopi tse qhibilihisang likhalase ho hlahisa motlakase. Metsi a phepelo ea boiler a futhumatsoa ho hlahisa mouoane o chesang haholo, ebe mouoane o chesang haholo o romelloa ho turbine ea mouoane ho holisa le ho etsa mosebetsi, ho fetolela matla a motlakase ho matla a mochini, ebe o khanna jenereithara ho hlahisa motlakase. Theknoloji ena ha e boloke matla feela, empa e boetse e thusa ho sireletsa tikoloho.
Xianning CSG e ile ea tsetela li-yuan tse limilione tse 23 kahong ea morero oa ho fehla matla a matla a litšila ka selemo sa 2013, 'me e ile ea hokahanngoa ka katleho le marang-rang ka Phato 2014. Lilemong tsa morao tjena, Xianning CSG e ntse e sebelisa thekenoloji ea ho hlahisa matla a matla a litšila ho fihlela matla le ho boloka matla. phokotso ea mosi indastering ea likhalase. Ho tlalehoa hore karolelano ea matla a fehlang ea setsi sa mocheso oa litšila oa Xianning CSG se ka bang limilione tse 40 tsa kWh. Ntho ea phetoho e baloa ho ipapisitsoe le tšebeliso e tloaelehileng ea mashala ea tlhahiso ea matla ea 0.350kg ea mashala a tloaelehileng/kWh le khase ea carbon dioxide ea 2.62kg/kg ea mashala a tloaelehileng. Ho fehla motlakase ho lekana le ho boloka 14,000. Lithane tsa mashala a tloaelehileng, a fokotsang ho ntšoa ha lithane tse 36 700 tsa carbon dioxide!
Sepheo sa "carbon peak" le "carbon neutrality" ke tsela e telele ea ho tsamaea. Likhamphani tsa likhalase li ntse li hloka ho tsoela pele ka boiteko ba tsona ba ho ntlafatsa theknoloji e ncha indastering ea likhalase, ho lokisa sebopeho sa tekheniki, le ho khothaletsa phethahatso e potlakileng ea merero ea naha ea heso ea "khabone e habeli". Ke lumela hore tlas'a tsoelo-pele ea saense le thekenoloji le temo e tebileng ea bahlahisi ba bangata ba likhalase, indasteri ea khalase ka sebele e tla finyella tsoelo-pele ea boleng bo phahameng, nts'etsopele e tala le nts'etsopele e tsitsitseng!
