Thaum Lub Peb Hlis 25, thawj lub tsheb ntawm PO / SM chav tsev ntawm Sinochem Quanzhou Petrochemical' s 1 lab tons / xyoo ethylene project tau ua tiav zoo thiab raug xa tawm ntawm lub hoobkas. Kev ua haujlwm ncaj ncees ntawm Quanzhou Petrochemical PO / SM cog tau ua rau cov kis ntawm propylene oxide sib xyaw cog cov khoom lag luam hauv xeev Fujian. In the face of loj lag luam xav tau, cov khoom yuav muab rau 12 lub ntsiab muag PO cov neeg siv khoom xws li Wanhua thiab Jiahua. Mainstream cov neeg siv khoom lag luam hauv Fujian xeev, Zhejiang thiab Jiangsu.
Tam sim no, kuv lub teb chaws cov roj ua kom rov qab muaj peev xwm ua tau zoo tshaj, thiab lub peev xwm muaj peev xwm tseem muaj cov khoom siv hauv cheeb tsam thiab xav tau tsis sib xws. Cov chaw lim dej nyob rau sab hnub tuaj Suav Tuam Tshoj thiab Qab Teb Tuam Tshoj muaj peev xwm txhawb kev cais thiab tshuaj sib xyaw ua ke thiab nce kev tsim tawm ntawm cov khoom siv tshuaj lom neeg kom tau raws li kev thov hauv cheeb tsam. Qhov txiaj ntsig zoo tshwj xeeb no tseem yuav ua rau kev txhim kho txuas ntxiv ntawm kuv lub teb chaws' s kev lag luam chemical nyob rau hauv cov kev taw qhia ntawm kev muaj peev xwm agglomeration thiab thaj av rov ua haujlwm.
PO / SM cov tshuab muaj kev pom zoo
PO / SM txheej txheem thev naus laus zis yog mas feem ntau los ntawm Lyondell Basell, Respol, Plhaub thiab lwm cov tuam txhab. Suav cov tuam txhab xws li Changzhou Ruihua Chemical Engineering Technology Co., Ltd. thiab Wanhua Chemical tau cog lus rau kev txhim kho thiab siv cov thev naus laus zis no.
PO / SM thev naus laus zis los ntawm Wanhua Chemical dhau los ua tiav qhov kev pom zoo ntawm Petrochemical Federation thaum Lub Ib Hlis 2019. Cov thev naus laus zis no tau txais txiaj ntsig zoo ntawm cov khoom pov tseg tsawg dua, cov txiaj ntsig ntxiv ntawm tus nqi sib koom ua ke, kev siv hluav taws xob tsawg, thiab kev lag luam zoo. Txawm li cas los xij, thev naus laus zis tau ntev dhau los kev lag luam txawv teb chaws. Txhawm rau txhawb kev thev naus laus zis kev lag luam propylene oxide kev lag luam, Wanhua Chemical tau tsim ib pab pawg los pib kev tshawb fawb ywj pheej thiab kev txhim kho ntawm propylene oxide raug tsim thev naus laus zis los ntawm co-oxidation ntawm ethylbenzene, thiab koom tes nrog Zhejiang University kom ua txoj haujlwm me me tshuab kev tshawb fawb. Nyob rau tib lub sijhawm, Wanhua Chemical tau tsim kev ywj pheej thiab tsim cov cuab yeej kuaj ntsuas nrog kev tsim tawm txhua xyoo ntawm 500 tons ntawm propylene oxide thiab 1,100 tons ntawm styrene, uas tseem tau cog lus thiab sim ua tiav, thiab tau tiav kev ua haujlwm ruaj khov rau ntau dua 90 hnub. Wanhua Chemical tau nqis peev txog 3.25 billion yuan los siv rau kev hloov pauv ntawm qhov kev kawm tau zoo hauv Yantai thiab tsim lub ntiaj teb kev lag luam cog nrog kev tsim tawm txhua xyoo ntawm 300,000 tons ntawm propylene oxide thiab 650,000 tons ntawm styrene. Cov cuab yeej yuav tsum tiav thiab muab tso rau hauv kev ua haujlwm hauv 2021.
Ruihua Chemical tau tsim nyob rau xyoo 2007 thiab mob siab rau kev tshawb nrhiav thiab kev tsim kho thiab txhawb nqa ntawm styrene localization txheej txheem thev naus laus zis. Nws tau hloov PO / SM thev naus laus zis rau ntau lub tuam txhab, suav nrog CITIC Guoan Chemical, Zhejiang Petrochemical Theem II, Jingbo Hydrocarbon Biochemical Technology, thiab lwm yam. Nws tau tshaj tawm tias 80,200,000 tuj / xyoo PO / SM qhov haujlwm ntawm CITIC Guoan Chemical tau ua tiav tiav. Raws li Xu Zhigang, Thawj Tswj ntawm Changzhou Ruihua Chemical Engineering Technology Co., Ltd., txhua qhov nyhav ntawm propylene oxide tsim los ntawm PO / SM cov txheej txheem yuav sib koom ua ke 2.2 txog 2.5 tons ntawm styrene. Qhov no yog qhov zoo ntawm cov txheej txheem no. Tshwj xeeb hauv kev ua kom huv thiab kev koom ua ke tshuaj, PO / SM txheej txheem muaj ntau qhov zoo.
Qhov nce hauv peev xwm ntau lawm yuav ua rau muaj kev kub ntxhov tshaj
Propylene oxide kev lag luam
Vim tias lub siab nqe tus nqi ntawm propylene oxide thiab qhov kev txhim kho zoo ntawm kev lag luam nqes hav zoov, txuas nrog kev sib txig sib txig hauv kev tsim kho ntsuab kev tiv thaiv ib puag ncig technology, cov haujlwm tshiab tau txuas ntxiv mus hauv xyoo tas los. Raws li cov ntaub ntawv, txog rau thaum xaus rau 2020, hauv kev tsim cov khoom muaj peev xwm ntawm propylene oxide yog 3.282 lab tons / xyoo, thiab Shandong Xinyue, Jilin Shenhua, thiab CNOOC thiab Shell yog qhov thib peb hauv Suav teb, nrog 350,000 tons / xyoo, 300,000 tons / xyoo thiab 29 10,000 tons / xyoo. Nrog kev ua kom tsis muaj zog ntawm kev cuam tshuam ntawm cov tshiab txoj hlab ntsws muaj kabmob sib kis, ntau qhov dej num ntawm propylene oxide yuav muab tso rau kev ua haujlwm hauv 2021, raws li qhia hauv Table 1.
Kev txav ceev ntawm qhov muaj peev xwm ntau lawm yuav muaj qhov cuam tshuam rau kev ua lag luam propylene oxide. Nws tuaj yeem pom los ntawm cov ntaub ntawv hauv Daim Ntawv 1 uas nyob rau xyoo 2021, tsib ntu ntawm cov cuab yeej yuav txais PO / SM cov txheej txheem ntau lawm, koom nrog PO ntau lawm muaj peev xwm ntawm 1.07 lab tons / xyoo.
Styrene kev lag luam
Los ntawm 2021 txog 2022, styrene thoob plaws lub tebchaws yuav nkag mus rau ib lub sijhawm ntawm kev tawg nyob rau hauv kev muaj peev xwm ntau lawm. Los ntawm qhov pom ntawm kev xa tawm kev faib tawm tshiab, kuv lub teb chaws' s styrene ntau lawm muaj peev xwm faib rau sab qaum teb. Nyob rau hauv 2020, lub domestic styrene ntau lawm muaj peev xwm yuav tau 2.65 lab tons, nce ntxiv ntawm 52%. Xyoo 2021, Tuam Tshoj' s tshiab styrene muaj peev xwm xav tau txog 5.62 lab tons / xyoo.
Ntawm lawv, Shandong npaj kom muab 1.49 lab tons / xyoo ntawm cov khoom siv styrene rau hauv ntau lawm. Los ntawm tom qab ntawd, tsuas yog Shandong Province lub styrene ntau lawm muaj peev xwm nce ntxiv mus rau 2.96 lab tons / xyoo. Thaum Shandong cov peev xwm tsim tawm tau nce ntau, Shandong cov kev lag luam nyob ib puag ncig kuj tseem pom qhov nce ntawm qhov muaj peev xwm ntau lawm. Ntawm lawv, Tianjin Bohua lub 450,000-tuj / xyoo cog thiab Luoyang Petrochemical cov 120,000-tuj / xyoo cov nroj tsuag tau npaj yuav muab tso rau hauv kev ua haujlwm hauv peb lub hlis thib peb; Sab Hnub Tuam Tshoj yuav muaj txog 1.41 lab tons ntawm cov nroj tsuag tshiab tso rau hauv kev khiav haujlwm. Kev ua lag luam hauv Shandong tsis yog tsuas yog muaj cov qauv hauv cheeb tsam muab kev sib tw, tab sis kuj yuav tsum ua rau thaj tsam thiab thaj chaw sib tw ntawm kev xa khoom sab qab teb. Txoj kev lag luam hauv khw styrene yog maj mam zuj zus.
