ALLY - Ukadaulo Wotsogola Wotsuka COG Wamtsogolo ku China: Kusanthula Kwanzeru kwa Kuchotsa Kaboni M'mafakitale

M'malo akuluakulu a mafakitale kumpoto kwa China, mawonekedwe aatali a mafakitale ophikira coke akhala chizindikiro cha kupanga chuma, komabe amanyamulanso mavuto azachilengedwe. Pamene usiku ukugwa pa malo opangidwa ndi zitsulo, kuwala kwa lalanje kwa ma uvuni a coke kumasonyeza vuto lakale: kupanga kwakukulu kwa Coke Oven Gas (COG) ngati chinthu china. M'mbuyomu, mpweya wambiri uwu unkayaka moto, zomwe zinapangitsa kuti mpweya wambiri wa carbon utuluke, kapena kugwiritsidwa ntchito molakwika ngati mafuta otsika.

Masiku ano, nkhani ikusintha. Kufunika kwa kusintha kwa mphamvu padziko lonse lapansi kwasintha "zinyalala zamafakitale" izi kukhala chuma chamtengo wapatali chopangira haidrojeni. Pakati pa kusinthaku paliUkadaulo Wotsogola Woyeretsa COG ku China, luso lofunika kwambiri lomwe limalumikiza kusiyana pakati pa mafakitale olemera achikhalidwe ndi tsogolo lopanda mpweya wa carbon. Mwa kutulutsa haidrojeni yoyera kwambiri kuchokera ku zosakaniza zovuta za mpweya, ukadaulo uwu umathetsa mavuto ofunikira kwambiri omwe amawononga chuma cha mafakitale pomwe umapereka gwero lokhazikika lamafuta am'deralo la chuma chomwe chikubwera cha haidrojeni, makamaka m'magawo achitsulo ndi mankhwala.

Kusintha kwa Padziko Lonse Kupita ku Kuchotsa Kaboni mu Mafakitale ndi Kuphatikiza kwa Hydrogen

Gawo la mafakitale padziko lonse lapansi pakadali pano lili pamavuto, poyenda movutikira kuchoka pa kudalira mafuta osungidwa ndi zinthu zakale kupita ku mphamvu zokhazikika. Mapangano apadziko lonse lapansi okhudza nyengo ayambitsa kayendetsedwe ka dziko lonse lapansi kuti achepetse mpweya woipa, makamaka m'magawo "ovuta kupirira" monga kupanga zitsulo, mayendedwe olemera, ndi kukonza mankhwala. Pachifukwa ichi, haidrojeni yatuluka ngati chonyamulira chachikulu cha mphamvu. Europe ndi North America apita patsogolo kwambiri pa haidrojeni wobiriwira, komabe vuto lomwe lilipo ndi mtengo ndi kukula kwa kupanga.

China, monga kampani yayikulu kwambiri padziko lonse lapansi yopanga zitsulo ndi coke, ili ndi udindo wapadera panjira iyi yapadziko lonse lapansi. Zolinga za boma la China za "Dual Carbon" - kukweza mpweya woipa wa carbon pofika chaka cha 2030 ndikukwaniritsa kusagwirizana ndi mpweya wa carbon pofika chaka cha 2060 - zaika mphamvu yayikulu pamafakitale achikhalidwe kuti apange zatsopano. Kulimbana kwakukulu kwa makampani sikungochepetsa mpweya woipa, komanso kuchita izi mwanjira yothandiza pazachuma. Kuyeretsa COG kumapereka yankho lothandiza komanso lothandiza kwambiri. Mwa kukonza mpweya wolemera wa hydrogen womwe wapangidwa kale panthawi yokonza coke, mafakitale amatha kuchepetsa kwambiri mpweya wawo wa carbon popanda kuyembekezera kuti zomangamanga zonse za electrolysis zikhwime. Cholinga cha dziko lino chikugwirizana ndi zoyesayesa zapadziko lonse lapansi kuti ziwonjezere kugwiritsa ntchito bwino zinthu ndipo zikuyimira maziko a chitetezo champhamvu cha China.

Ubwino Waukulu wa Kuyeretsa COG mu Mphamvu Zamakono

Njira yosinthira mpweya wa coke kukhala hydrogen wamafuta ndi yovuta kwambiri, yomwe imafuna kuchotsa zinthu zovuta monga phula, naphthalene, ammonia, ndi sulfure yachilengedwe. Kusintha kwa kuyeretsa ma cog kwapita patsogolo kwambiri komanso kugwiritsa ntchito mphamvu zochepa. Machitidwe amakono tsopano akugwiritsa ntchito ukadaulo wapamwamba wa Pressure Swing Adsorption (PSA), womwe umalola kulekanitsa hydrogen mosankha pamavuto osiyanasiyana. Ukadaulo wapaderawu woyeretsa ma cog muCHina yakonzedwa kuti ikwaniritse kuchuluka kwa chiyero chopitilira 99.999%, kukwaniritsa zofunikira zolimba za makampani opanga ma hydrogen fuel cell vehicle (HCV).

Chimodzi mwa zinthu zodziwika bwino za makina atsopano oyeretsera ma cog ndi kusinthasintha kwawo ku mitundu yosiyanasiyana ya mpweya wodyetsa. Machitidwe a mafakitale nthawi zambiri samakhala olimba; mtundu wa COG yaiwisi umatha kusiyana kutengera mitundu ya malasha ndi kutentha kwa uvuni. Mayunitsi oyeretsera apamwamba tsopano akuphatikiza makina owongolera anzeru omwe amayang'anira kulowa kwa gasi nthawi yeniyeni, kusintha kayendedwe ka kulowetsedwa kuti asunge mtundu wogwirizana. Kuphatikiza apo, kuphatikiza kuyeretsa kwa magawo ambiri—kuphatikiza kukonza koyambirira, kuyeretsa bwino, ndi magawo omaliza a PSA—kumatsimikizira kuti moyo wa catalyst ndi absorbent ndi wokwera, kuchepetsa mtengo wonse wa umwini wa ogwira ntchito m'mafakitale. Kukhwima kwaukadaulo kumeneku pakuyeretsa ma cog ndi komwe kumathandiza mphero zazikulu zachitsulo kusintha kukhala malo opangira mphamvu, kupereka haidrojeni yoyera pamakampani awoawo kapena misika yamagetsi yamadera.

Kusanthula Kwanzeru: Kuphatikiza Ukadaulo wa Kuchotsa Kaboni M'thupi Mozama

Kuchotsa mpweya m'thupi si njira yothetsera vuto limodzi koma ndi njira yogwirira ntchito yonse. Kuti zinthu ziyende bwino m'mafakitale, kuyeretsa ma cog kuyenera kuonedwa ngati gawo la kayendetsedwe ka mphamvu. Izi sizimangokhudza kuchotsa hydrogen komanso kukanikiza, kusungira, ndi kugwiritsa ntchito mtsogolo. Njira yokwanira yogwirira ntchito m'mafakitale imaphatikizapo moyo wonse wa polojekitiyi—kuyambira kupanga ndi kupanga ukadaulo woyamba mpaka kuyambitsa ntchito ndi chithandizo chaukadaulo cha nthawi yayitali. Mwa kupereka mayankho athunthu a hydrogen, kuphatikiza electrolysis yamadzi ndi kusintha kwa methanol kukhala hydrogen pamodzi ndi kuyeretsa ma cog, opereka ukadaulo angathandize mabizinesi kusintha mphamvu zawo kutengera zinthu zomwe zilipo m'deralo.

Kafukufuku wopambana wa mafakitale ku China akuwonetsa kuti njira yolumikiziranayi ikugwira ntchito bwino. Mwachitsanzo, magulu akuluakulu a mankhwala agwiritsa ntchito bwino mayunitsi oyeretsera omwe amakonza ma cubic metres mazana ambiri a mpweya pa ola limodzi, zomwe zimapangitsa kuti pakhale zinthu zopangira ammonia kapena hydrogen yoyera kwambiri popanga zamagetsi. Mapulojekitiwa amatsimikizira kuti kuyeretsa ma cog si njira yongotsatira malamulo a chilengedwe koma ndi njira yowonjezera phindu la mafakitale. Akaphatikizidwa ndi ntchito zaukadaulo za EPC (Engineering, Procurement, and Construction) ndi mapangidwe okhazikika, ukadaulo uwu ukhoza kugwiritsidwa ntchito mwachangu, zomwe zimathandiza makampani kukwaniritsa zolinga zawo zokhazikika mkati mwa nthawi yokhazikika.

Kutsogolera Njira Yopita Kutsogolo Lokhazikika la Hydrogen

Ulendo wopita ku chuma chozikidwa pa haidrojeni umafuna kuphatikiza chidziwitso chakuya chamakampani ndi kafukufuku wamakono. Ally Hydrogen Energy, kampani yaukadaulo yapamwamba yapadziko lonse yomwe ili ku Chengdu High-Tech Zone, yakhala zaka 25 ikutsogolera kayendetsedwe kameneka. Kampaniyo, yomwe kale inkadziwika kuti Ally Hi-Tech, yasintha kukhala mphamvu yotsogola mumakampani opanga haidrojeni ku China, ikuyang'ana kwambiri pa kafukufuku, chitukuko, ndi kukwezedwa kwa msika wa mayankho apamwamba amagetsi. Ndi mbiri yayitali yotumikira makampani akuluakulu apadziko lonse lapansi komanso akunyumba monga Sinopec, PetroChina, Air Liquide, ndi Linde, kampaniyo yadzikhazikitsa ngati kampani yoyenerera yopereka makampani apamwamba padziko lonse lapansi.

Mwa kuyang'ana kwambiri pakugwiritsa ntchito ukadaulo, Ally yakulitsa kufikira kwake kuchokera ku kuyeretsedwa kwapakati mpaka ku unyolo wonse wamtengo wapatali wa hydrogen. Kudzipereka kwawo ku khalidwe ndi ntchito kwalimbikitsa mgwirizano wa nthawi yayitali padziko lonse lapansi, kuphatikizapo mgwirizano ndi Plug Power ku United States ndi Iwatani ku Japan. Pamene dziko lapansi likuyandikira zolinga zake zosagwirizana ndi mpweya, udindo wa opereka chithandizo chapadera popereka ukadaulo wamphamvu, wothandiza, komanso wowonjezera woyeretsa ma cog muCHina ikukhala yofunika kwambiri. Kudzera mu kusanthula kwanzeru komanso luso laukadaulo, kusintha kuchoka ku zinthu zakale zamafakitale kupita ku mphamvu zoyera sikungokhala kotheka kokha—ndi zenizeni zomwe zikuchitika.
