Thaum Lub Xya Hli 1, 2022, kev pib ua koob tsheej ntawm thawj theem ntawm 300,000 tujmethyl methacrylate(tom qab no hu ua methyl methacrylate) MMA qhov project ntawm Henan Zhongkepu Raw thiab Cov Khoom Tshiab Co., Ltd. tau muaj nyob rau hauv Puyang Economic thiab Technological Development Zone, kos npe rau daim ntawv thov ntawm thawj txheej tshiab ionic kua catalytic ethylene MMA technology ntawm nws tus kheej tsim los ntawm CAS thiab Zhongyuan Dahua.Qhov no kuj yog thawj ethylene MMA tsob nroj luam tawm hauv Suav teb.Yog tias cov cuab yeej tau ua tiav tiav rau hauv kev tsim khoom, nws yuav ua tiav kev ua tiav hauv Tuam Tshoj cov khoom siv ethylene MMA, uas muaj kev cuam tshuam tseem ceeb heev rau kev lag luam MMA.
Qhov thib ob MMA chav tsev ntawm cov txheej txheem ethylene hauv Suav teb tuaj yeem tshaj tawm hauv Shandong.Nws yog thawj zaug xav tias yuav muab tso rau hauv kev tsim khoom ib puag ncig 2024, thiab tam sim no nyob rau hauv qhov kev pom zoo ua ntej.Yog tias chav tsev muaj tseeb, nws yuav dhau los ua MMA chav tsev thib ob ntawm cov txheej txheem ethylene hauv Suav teb, uas yog qhov tseem ceeb rau kev sib txawv ntawm MMA cov txheej txheem tsim khoom hauv Suav teb thiab kev txhim kho ntawm Tuam Tshoj cov tshuaj lom neeg kev lag luam.
Raws li cov ntaub ntawv cuam tshuam, muaj cov txheej txheem MMA hauv qab no hauv Suav teb: C4 txheej txheem, ACH txheej txheem, txhim kho ACH txheej txheem, BASF ethylene txheej txheem thiab Lucite ethylene txheej txheem.Thoob plaws ntiaj teb, cov txheej txheem tsim khoom no muaj kev tsim khoom lag luam.Hauv Suav teb, txoj cai C4 thiab ACH txoj cai tau raug tsim kho, thaum txoj cai ethylene tsis tau ua tiav kev lag luam.
Vim li cas Tuam Tshoj cov tshuaj lom neeg kev lag luam nthuav dav nws cov ethylene MMA cog?Puas yog tus nqi tsim khoom ntawm MMA ua los ntawm ethylene txoj kev sib tw?
Ua ntej, cov nroj tsuag ethylene MMA tau tsim ib qho dawb paug nyob rau hauv Suav teb thiab muaj qib siab ntau lawm technology.Raws li kev tshawb fawb, tsuas muaj ob pawg ntawm ethylene MMA units hauv ntiaj teb, uas nyob hauv Europe thiab North America feem.Cov txheej txheem ntawm ethylene MMA units yog qhov yooj yim.Qhov kev siv atomic yog ntau dua 64%, thiab cov txiaj ntsig tau siab dua lwm hom txheej txheem.BASF thiab Lucite tau ua tiav kev tshawb fawb thiab kev tsim kho cov cuab yeej MMA rau cov txheej txheem ethylene ntxov heev, thiab ua tiav kev lag luam.
MMA chav tsev ntawm cov txheej txheem ethylene tsis koom nrog cov khoom siv acidic, uas tseem ua rau cov khoom siv qis qis, cov txheej txheem tsim khoom ib puag ncig, thiab lub sijhawm ua haujlwm ntev thiab lub voj voog.Nyob rau hauv cov ntaub ntawv no, tus nqi depreciation ntawm MMA chav tsev nyob rau hauv ethylene txheej txheem thaum lub sij hawm ua hauj lwm yog qis dua li ntawm lwm yam txheej txheem.
Cov khoom siv Ethylene MMA kuj muaj qhov tsis zoo.Ua ntej, kev txhawb nqa cov chaw rau cov nroj tsuag ethylene yog xav tau, nyob rau hauv uas ethylene feem ntau yog tsim los ntawm kev koom ua ke cov nroj tsuag, yog li yuav tsum tau txhawb kev loj hlob ntawm kev lag luam integrated.Yog tias ethylene raug yuav, kev lag luam tsis zoo.Qhov thib ob, tsuas muaj ob pawg ntawm ethylene MMA cov cuab yeej hauv ntiaj teb.Tuam Tshoj cov dej num hauv kev tsim kho siv thev naus laus zis ntawm Suav Academy ntawm Kev Tshawb Fawb, thiab lwm cov lag luam tsis tuaj yeem yooj yim thiab zoo tau txais cov cuab yeej technology.Thib peb, cov khoom siv MMA ntawm cov txheej txheem ethylene muaj cov txheej txheem ntev, cov peev txheej loj, ntau cov tshuaj chlorine uas muaj cov dej khib nyiab yuav raug tsim tawm hauv cov txheej txheem tsim khoom, thiab cov nqi kho mob ntawm peb cov khib nyiab yog siab.
Qhov thib ob, tus nqi sib tw ntawm MMA chav tsev feem ntau yog los ntawm kev txhawb nqa ethylene, thaum sab nraud ethylene tsis muaj qhov sib tw kom zoo dua.Raws li kev tshawb nrhiav, MMA chav tsev ntawm ethylene txoj kev yog 0.4294 tons ntawm ethylene, 0.387 tons ntawm methanol, 661.35 Nm ³ Synthetic gas, 1.0578 tons ntawm crude chlorine yog tsim los ntawm cov tshuaj tiv thaiv, thiab tsis muaj methacrylic acid khoom nyob rau hauv cov txheej txheem ntau lawm. .
Raws li cov ntaub ntawv cuam tshuam los ntawm Shanghai Yunsheng Chemical Technology Co., Ltd., MMA tus nqi ntawm ethylene txoj kev yog kwv yees li 12000 yuan / tuj thaum ethylene yog 8100 yuan / ton, methanol yog 2140 yuan / ton, roj hluavtaws yog 1.95 yuan / cubic meter, thiab chlorine crude yog 600 yuan / ton.Piv nrog rau tib lub sijhawm, cov nqi raug cai ntawm C4 txoj kev thiab ACH txoj kev yog siab.Yog li, raws li kev lag luam tam sim no, ethylene MMA tsis muaj kev sib tw ntawm kev lag luam.
Txawm li cas los xij, kev tsim khoom ntawm MMA los ntawm txoj kev ethylene yuav zoo sib xws nrog cov peev txheej ethylene.Ethylene yog qhov pib los ntawm naphtha cracking, thee synthesis, thiab lwm yam. Nyob rau hauv rooj plaub no, kev sib tw ntawm MMA ntau lawm los ntawm ethylene txoj kev yuav raug cuam tshuam los ntawm tus nqi ntawm ethylene raw cov ntaub ntawv.Yog hais tias ethylene raw khoom yog muab rau tus kheej, nws yuav tsum tau muab xam raws li tus nqi ntawm ethylene, uas yuav ua rau kom tus nqi sib tw ntawm ethylene MMA zoo heev.
Thib peb, ethylene MMA siv cov tshuaj chlorine ntau, thiab tus nqi thiab kev txhawb nqa kev sib raug zoo ntawm cov tshuaj chlorine kuj tseem txiav txim siab tus yuam sij rau tus nqi sib tw ntawm ethylene MMA.Raws li cov txheej txheem tsim khoom ntawm BASF thiab Lucite, ob qho tib si ntawm cov txheej txheem no yuav tsum tau haus cov tshuaj chlorine ntau.Yog tias cov tshuaj chlorine muaj nws tus kheej kev txhawb nqa kev sib raug zoo, tus nqi ntawm cov tshuaj chlorine tsis tas yuav tsum tau txiav txim siab, uas yuav txhim kho cov nqi sib tw ntawm ethylene MMA.
Tam sim no, ethylene MMA tau nyiam qee qhov kev mloog feem ntau vim yog kev sib tw ntawm cov nqi tsim khoom thiab kev ua haujlwm me me ntawm chav tsev.Tsis tas li ntawd, cov kev cai rau kev txhawb nqa cov ntaub ntawv raw kuj ua raws li txoj kev loj hlob tam sim no ntawm Tuam Tshoj txoj kev lag luam tshuaj.Yog tias lub tuam txhab txhawb nqa ethylene, chlorine thiab cov roj synthesis, ces ethylene MMA tej zaum yuav yog tus nqi sib tw MMA ntau lawm hom tam sim no.Tam sim no, txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam tshuaj lom neeg feem ntau yog cov chaw txhawb nqa.Raws li cov qauv no, ethylene txoj kev sib piv nrog ethylene MMA yuav dhau los ua qhov tseem ceeb ntawm kev lag luam.
