Ib lub lim tiam tom qab tso tawm ntawm tsoomfwv Askiv lub tswv yim hydrogen, kev sim siv 100% hydrogen los tsim cov iav ntab tau pib hauv thaj tsam Liverpool, uas yog thawj zaug hauv ntiaj teb.
Fossil fuels xws li natural gas feem ntau siv nyob rau hauv cov txheej txheem ntau lawm yuav raug hloov tag nrho los ntawm hydrogen, uas qhia tau hais tias cov iav kev lag luam tuaj yeem txo cov pa roj carbon emissions thiab ua ib kauj ruam loj rau kev ua tiav lub hom phiaj ntawm net xoom.
Qhov kev sim no tau ua nyob rau ntawm lub Hoobkas St Helens hauv Pilkington, lub tuam txhab iav British, qhov chaw uas lub tuam txhab pib tsim iav hauv xyoo 1826. Yuav kom decarbonize hauv UK, yuav luag txhua qhov kev lag luam yuav tsum tau hloov pauv tag nrho. Kev lag luam suav txog 25% ntawm tag nrho cov tsev cog khoom tso pa tawm hauv UK, thiab txo cov emissions yog qhov tseem ceeb yog tias lub teb chaws yuav tsum ncav cuag "zero".
Txawm li cas los xij, kev lag luam siv hluav taws xob siv hluav taws xob yog ib qho nyuaj tshaj plaws los daws. Kev lag luam emissions, xws li iav tsim, tshwj xeeb tshaj yog nyuaj los txo cov emissions-los ntawm qhov kev sim no, peb yog ib kauj ruam los ze zog mus kov yeej qhov teeb meem no. Qhov project "HyNet Industrial Fuel Conversion" project yog coj los ntawm Progressive Energy, thiab hydrogen yog muab los ntawm BOC, uas yuav muab HyNet nrog kev ntseeg siab los hloov cov pa roj carbon monoxide tsawg.
Qhov no yog suav tias yog lub ntiaj teb thawj qhov kev ua yeeb yam loj ntawm 100% hydrogen combustion nyob rau hauv lub neej ntab (daim ntawv) iav ntau lawm ib puag ncig. Qhov kev sim Pilkington hauv tebchaws United Kingdom yog ib qho ntawm ntau qhov haujlwm tsis tu ncua nyob rau sab qaum teb sab hnub poob tebchaws Askiv los sim seb hydrogen tuaj yeem hloov cov fossil fuels hauv kev tsim khoom. Tom qab xyoo no, kev sim ntxiv ntawm HyNet yuav muaj nyob hauv Port Sunlight, Unilever.
Cov haujlwm ua qauv qhia no yuav koom ua ke txhawb kev hloov pauv ntawm iav, zaub mov, dej haus, hluav taws xob thiab kev lag luam pov tseg rau kev siv cov pa roj carbon tsawg los hloov lawv cov roj fossil. Ob qhov kev sim siv hydrogen muab los ntawm BOC. Thaum Lub Ob Hlis 2020, BEIS tau muab 5.3 lab phaus hauv kev pab nyiaj rau HyNet Industrial Fuel Conversion Project los ntawm nws txoj haujlwm tshiab zog.
"HyNet yuav coj kev ua haujlwm thiab kev loj hlob ntawm kev lag luam rau thaj tsam Northwest thiab pib kev lag luam qis carbon. Peb tau tsom mus rau kev txo qis emissions, tiv thaiv 340,000 txoj haujlwm tsim khoom uas twb muaj lawm hauv thaj av Northwest, thiab tsim ntau dua 6,000 txoj haujlwm ruaj khov tshiab. , Muab cov cheeb tsam ntawm txoj hauv kev los ua tus thawj coj hauv ntiaj teb hauv kev tsim hluav taws xob huv huv. "
Matt Buckley, UK tus thawj tswj hwm ntawm Pilkington UK Ltd., ib lub koom haum ntawm NSG Group, tau hais tias: "Pilkington thiab St Helens ib zaug ntxiv sawv ntawm qhov ua ntej ntawm kev tsim kho tshiab thiab ua lub ntiaj teb thawj qhov kev sim hydrogen ntawm cov iav ntab iav ntau lawm."
"HyNet yuav yog kauj ruam tseem ceeb los txhawb peb cov dej num decarbonization. Tom qab ob peb lub lis piam ntawm tag nrho cov kev sim ntau lawm, nws tau ua tiav cov pov thawj tias nws muaj peev xwm ua tau lub float iav Hoobkas nrog hydrogen yam xyuam xim thiab zoo. Tam sim no peb tos ntsoov rau lub tswv yim HyNet dhau los ua qhov tseeb. "
Tam sim no, ntau thiab ntau lub tuam txhab iav tau nce R & D thiab kev tsim kho tshiab ntawm kev txuag hluav taws xob thiab emission-txo cov thev naus laus zis, thiab siv cov thev naus laus zis tshiab los tswj lub zog noj ntawm iav ntau lawm. Tus editor yuav sau peb rau koj.
1. Oxygen combustion technology
Oxygen combustion yog hais txog cov txheej txheem ntawm kev hloov cov pa nrog oxygen hauv cov txheej txheem ntawm cov roj combustion. Cov thev naus laus zis no ua rau kwv yees li 79% ntawm cov nitrogen hauv huab cua tsis koom nrog hauv kev sib txuas ntxiv, uas tuaj yeem ua kom cov nplaim taws kub thiab ua kom nrawm nrawm. Tsis tas li ntawd, cov pa roj emissions thaum lub sij hawm oxy-fuel combustion yog li ntawm 25% mus rau 27% ntawm huab cua combustion, thiab cov melting tus nqi kuj tseem txhim khu kev qha, mus txog 86% mus rau 90%, uas txhais tau hais tias thaj tsam ntawm lub cub tawg yuav tsum tau. kom tau txais tib lub iav yog txo. Me me.
Thaum Lub Rau Hli 2021, raws li qhov kev txhawb nqa tseem ceeb hauv kev lag luam hauv Sichuan Xeev, Sichuan Kangyu Electronic Technology tau ua tiav txoj haujlwm tseem ceeb ntawm nws cov pa roj carbon monoxide tag nrho, uas yog qhov tseem ceeb rau kev hloov hluav taws xob thiab nce qhov kub thiab txias. Txoj kev tsim kho yog "ultra-thin electronic cover iav substrate, ITO conductive iav substrate", uas yog tam sim no qhov loj tshaj plaws ib-kiln ob-kab tag nrho-oxygen combustion ntab hluav taws xob iav ntau lawm kab hauv Suav teb.
Lub tuam tsev melting ntawm qhov project txais oxy-roj combustion + hluav taws xob boosting tshuab, cia siab rau oxygen thiab natural gas combustion, thiab pab melting los ntawm hluav taws xob boosting, thiab lwm yam, uas yuav tsis tsuas txuag 15% mus rau 25% roj noj, tab sis kuj. nce lub kiln Cov zis rau ib chav tsev cheeb tsam ntawm lub cub tawg tsub kom qhov ntau lawm efficiency li ntawm 25%. Tsis tas li ntawd, nws tseem tuaj yeem txo cov pa pa tawm, txo qhov kev faib ua feem ntawm NOx, CO₂ thiab lwm yam nitrogen oxides uas tsim los ntawm combustion ntau dua 60%, thiab pab daws qhov teeb meem ntawm qhov chaw emissions!
2. Flue gas denitration technology
Lub hauv paus ntsiab lus ntawm flue gas denitration technology yog siv oxidant los oxidize NOX rau NO2, thiab tom qab ntawd cov generated NO2 yog absorbed los ntawm dej los yog alkaline tov kom tiav denitration. Cov thev naus laus zis feem ntau yog muab faib ua kev xaiv catalytic txo denitrification (SCR), xaiv tsis-catalytic txo denitrification (SCNR) thiab ntub dej flue roj denitrification.
Tam sim no, hais txog kev kho cov roj pov tseg, cov tuam txhab iav hauv cheeb tsam Shahe tau tsim cov chaw SCR denitration, siv ammonia, CO lossis hydrocarbons los txo cov neeg ua haujlwm kom txo tau NO hauv cov pa nkev rau N2 thaum muaj cov pa.
Hebei Shahe Kev Nyab Xeeb Industrial Co., Ltd. 1-8 # iav rauv flue roj desulfurization, denitrification thiab plua plav tshem tawm thaub qab kab EPC project. Txij li thaum nws tau ua tiav thiab muab tso rau hauv kev ua haujlwm thaum lub Tsib Hlis 2017, qhov kev tiv thaiv ib puag ncig tau ua haujlwm ruaj khov, thiab cov pa phem hauv cov pa taws tuaj yeem ncav cuag cov ntsiab lus tsawg dua 10 mg / N㎡, sulfur dioxide tsawg dua 50 mg / N. ㎡, thiab nitrogen oxides tsawg dua 100 mg / N ㎡, thiab cov pa phem emission indicators, As mus txog tus qauv ruaj khov rau lub sijhawm ntev.
3. Kev siv hluav taws xob hluav taws xob pov tseg
Iav melting furnace pov tseg hluav taws xob hluav taws xob tsim hluav taws xob yog cov cuab yeej siv hluav taws xob pov tseg kom rov qab thermal zog los ntawm cov khib nyiab kub ntawm iav melting rauv los tsim hluav taws xob. Lub boiler pub dej yog rhuab los tsim superheated chav, thiab tom qab ntawd cov chav superheated xa mus rau chav turbine kom nthuav dav thiab ua haujlwm, hloov hluav taws xob rau hauv tshuab hluav taws xob, thiab tom qab ntawd tsav lub tshuab hluav taws xob los tsim hluav taws xob. Cov thev naus laus zis no tsis yog tsuas yog txuag hluav taws xob xwb, tab sis kuj tseem ua rau muaj kev tiv thaiv ib puag ncig.
Xianning CSG tau nqis peev 23 lab yuan hauv kev tsim kho cov khoom siv hluav taws xob pov tseg hluav taws xob hauv xyoo 2013, thiab nws tau ua tiav kev sib txuas ntawm daim phiaj nyob rau lub Yim Hli 2014. Nyob rau xyoo tas los no, Xianning CSG tau siv cov tshuab hluav taws xob pov tseg hluav taws xob kom ua tiav lub zog txuag thiab emission txo hauv kev lag luam iav. Nws tau tshaj tawm tias qhov nruab nrab lub zog tsim hluav taws xob ntawm Xianning CSG khib nyiab hluav taws xob hluav taws xob yog li 40 lab kWh. Kev hloov pauv tau suav nrog raws li tus qauv thee siv hluav taws xob tsim hluav taws xob ntawm 0.350kg ntawm cov qauv thee / kWh thiab carbon dioxide emission ntawm 2.62kg / kg ntawm cov qauv thee. Lub zog tsim hluav taws xob sib npaug li txuag 14,000. Tons ntawm tus qauv thee, txo cov pa tawm ntawm 36,700 tons ntawm carbon dioxide!
Lub hom phiaj ntawm "carbon ncov" thiab "carbon neutrality" yog txoj kev mus ntev. Cov tuam txhab iav tseem xav tau txuas ntxiv lawv cov kev siv zog los txhim kho cov thev naus laus zis tshiab hauv kev lag luam iav, kho cov qauv kev lag luam, thiab txhawb kev ua kom nrawm nrawm ntawm kuv lub teb chaws cov hom phiaj "dual carbon". Kuv ntseeg tias nyob rau hauv txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis thiab kev cog qoob loo sib sib zog nqus ntawm ntau lub tuam txhab iav, kev lag luam iav yuav muaj tseeb ua tiav txoj kev loj hlob zoo, kev loj hlob ntsuab thiab kev loj hlob ruaj khov!
