Covpropylene oxide kev lag luam"Jinjiu" txuas ntxiv nws qhov nce yav dhau los, thiab kev ua lag luam tsoo los ntawm 10000 yuan (tus nqi tuj, tib yam hauv qab no) pib. Kev ua lag luam Shandong ua piv txwv, tus nqi lag luam tau nce mus rau 10500 ~ 10600 yuan rau lub Cuaj Hlis 15, nce txog 1000 yuan txij thaum lub Yim Hli kawg. Thaum lub Cuaj Hlis 20, nws poob rov qab mus txog 9800 yuan. Nyob rau hauv lub neej yav tom ntej, cov khoom lag luam yuav tsum loj hlob, lub caij nyoog xav tau tsis muaj zog, thiab propylene oxide fluctuates hauv 10000 yuan.
Kev nce ntawm propylene oxide unit restart mov
Thaum Lub Yim Hli, tag nrho ntawm 8 pawg ntawm propylene oxide tau kho dua tshiab hauv Suav teb, suav nrog tag nrho cov peev txheej ntawm 1222000 tons / xyoo thiab tag nrho poob ntawm 61500 tons. Nyob rau lub Yim Hli, cov khoom tsim tawm ntawm cov nroj tsuag propylene oxide yog 293200 tons, poob 2.17% lub hli nyob rau lub hli, thiab qhov peev xwm siv tau yog 70.83%.
Thaum lub Cuaj Hlis, Sinochem Quanzhou propylene oxide chav tsev tau raug kaw rau kev saib xyuas, Tianjin Bohai Tshuaj, Changling, Shandong Huatai thiab lwm cov chav tau rov pib ua tiav, thiab Jinling chav tsev tau txo mus rau ib nrab ntawm kev ua haujlwm. Tam sim no, kev khiav hauj lwm tus nqi ntawm propylene oxide yog ze rau 70%, me ntsis qis dua li lub Yim Hli.
Nyob rau hauv lub neej yav tom ntej, Shandong Daze lub 100000 t / ib chav tsev yuav rov pib dua nyob rau hauv lig Cuaj hlis, thiab Jincheng Petrochemical lub 300000 t / ib chav tsev yuav tsum tau muab tso rau hauv ntau lawm thaum lub Cuaj Hli Ntuj kawg; Jinling thiab Huatai cov nroj tsuag tau rov qab mus rau ntau lawm ib kauj ruam. Cov khoom lag luam feem ntau yog nce ntxiv, thiab cov tub lag luam muaj kev poob qis dua. Nws cia siab tias kev ua lag luam propylene oxide yuav pom qhov tsis muaj zog ntawm kev tsis txaus ntseeg nyob rau hauv qhov nce ntawm cov khoom siv concentration, nrog kev pheej hmoo me me.
propylene oxide raw khoom txhawb nqa yuav tsum nyuaj
Rau cov khoom siv raw khoom propylene thiab kua chlorine, txawm hais tias "Jinjiu" tau ua rau muaj kev nce qib hauv kev lag luam, nws xav tias nws yuav yooj yim dua poob dua li nce hauv kev lag luam yav tom ntej, uas yuav nyuaj rau kev tsim kom muaj zog rub. tus dej ntws.
Thaum lub Cuaj Hlis, tus nqi ntawm propylene, cov khoom siv hluav taws xob sab saud, txuas ntxiv mus rau kev poob siab, uas tseem muab kev txhawb zog rau kev lag luam propylene oxide. Wang Quanping, tus thawj coj ua haujlwm ntawm Shandong Kenli Petrochemical Group, tau hais tias cov khoom siv hauv tsev propylene tseem nruj, nrog kev ua tau zoo nyob rau sab qaum teb, nruab nrab thiab sab hnub tuaj Suav teb. Tsis tas li ntawd, qee qhov kev saib xyuas cov khoom siv hauv qab ntawm propylene, xws li Tianjian Butyl Octanol, Dagu Epoxy Propane, thiab Kroll Acrylonitrile, tau rov tsim kho. Yog li ntawd, kev lag luam xav tau tau nce siab, cov lag luam propylene tau muag zoo, thiab cov khoom muag qis tau ua rau cov nqi propylene nce siab.
Los ntawm qhov kev xav ntawm chav ua haujlwm, ntawm ib sab, Xintai Petrochemical thiab propylene units tau rov pib dua, tab sis qhov cuam tshuam tau raug txwv vim muaj kev qeeb qeeb. Nyob rau tib lub sijhawm, qee qhov kev tsim tawm tshiab ntawm propane dehydrogenation rau propylene hauv Shandong tau muab tso rau hauv kev ua haujlwm tsawg dua li qhov xav tau, thiab tag nrho cov khoom siv tau kuj tswj tau. Ntawm qhov tod tes, nyob rau yav tom ntej, qee qhov loj nyob rau sab qaum teb sab hnub poob tau raug kaw rau kev saib xyuas, thiab qhov pib ntawm propylene nyob rau sab qaum teb sab hnub poob tau nqis mus rau 73.42%. Kev ncig ntawm peripheral propylene cov khoom tau poob qis heev. Tsis tas li ntawd, qee cov nroj tsuag qaum teb sab hnub poob tau khaws cov propylene xav tau rau kev tsim khoom sab nraud, thiab cov khoom siv ntawm peripheral propylene tau nruj heev.
Nyob rau hauv lub neej yav tom ntej, chav tsev load ntawm propylene cov lag luam yog qhov ruaj khov, thiab tsis muaj kev cia siab ntawm kev hloov pauv tseem ceeb hauv propylene mov. Cov cheeb tsam peripheral ntawm Shandong thiab East Tuam Tshoj yuav tseem tuav cov khoom siv nruj. Downstream nyiam ua rau tsis muaj zog nrog lub phaj, inhibiting kev txaus siab ntawm kev yuav khoom ntawm propylene downstream. Yog li ntawd, kev lag luam propylene tam sim no nyob rau hauv qhov xwm txheej ntawm cov khoom tsis muaj zog thiab kev thov, tab sis cov khoom siv qis qis qis qis, propylene oxide, acrylonitrile thiab lwm yam kev lag luam tau nce lawv cov load, thiab cov kev xav tau nruj tseem muaj qee qhov kev txhawb nqa. Nws cia siab tias tus nqi propylene tom ntej yuav hloov pauv hauv qhov nqaim, nrog kev txwv tsis pub nce thiab poob.
Lwm cov khoom siv raw, kua chlorine, yog ib qho tseem ceeb hauv kev ua lag luam. Kev muag khoom sab nraud ntawm qee cov khoom siv tu ntawm cov chaw tsim khoom loj tau txo qis me ntsis, thiab qee lub tuam txhab hauv nruab nrab Shandong tsis ruaj khov, uas txhawb kev lag luam txuas ntxiv mus rau qee qhov. Kev poob qis ntawm lub zog tseem ceeb hauv East Tuam Tshoj tau zoo, qhov kev thov tau yooj yim, thiab qee cov khoom siv tau raug kaw rau kev saib xyuas. Cov khoom siv tau poob qis. Qhov xwm txheej zoo ntawm cov khoom siv thiab kev xav tau sab nrauv tau ua rau muaj kev nce siab hauv kev ua lag luam Shandong, ua rau tag nrho cov kev lag luam tsom mus rau kev lag luam kom txav mus los. Meng Xianxing tau hais tias nrog kev rov qab los ntawm cov khoom siv txo qis thiab nce cov khoom siv, tus nqi ntawm cov tshuaj chlorine tuaj yeem poob rau lub sijhawm tom qab.
Qhov kev thov rau propylene oxide yog qeeb thiab nyuaj rau kev vam meej hauv lub caij nyoog siab
Polyether polyol yog cov khoom lag luam tseem ceeb tshaj plaws ntawm propylene oxide thiab cov khoom siv tseem ceeb rau polyurethane synthesis. Lub zuag qhia tag nrho overcapacity ntawm domestic polyurethane downstream kev lag luam, tshwj xeeb tshaj yog lub siab tshaj ntawm cov mos mos ua lag luam, yog loj.
Meng Xianxing tau hais tias nyob rau lub Cuaj Hli, tau tsav los ntawm cov nqi, cov khoom lag luam muag muag muag muag muag muag, thiab kev lag luam tseem ceeb txuas ntxiv txhawb kev lag luam, tab sis kev ua haujlwm qis qis yog qhov nruab nrab, thiab qhov nruab nrab thiab qis qis tseem qis.
Tam sim no, cov dej ntws hauv qab tsis tu ncua, tus nqi nce siab tseem yuav tsum tau xa mus ntxiv, qhov nruab nrab thiab qis qis qis qis qis qis qis qis thiab tos, thiab cov khoom lag luam tseem muaj teeb meem. Nyob rau hauv lub neej yav tom ntej, txawm hais tias cov xov xwm phem tiag tiag tseem tsis tau tsim, ntau lub tuam txhab tseem tsis muaj qhov chaw vim tus nqi clamping, thiab lawv lub luag haujlwm hauv kev txhawb nqa cov khoom siv raw khoom yog txwv.
Ntawm qhov tod tes, lub downstream nyuaj ua npuas ncauj polyether kev ua lag luam tuav ib tug maj mam upward sib, thiab nruab nrab thiab qis mus txog rau qhov kev thov. Txawm hais tias tag nrho cov dej num tau qis dua tib lub sijhawm, nws tau zoo dua piv nrog rau lub quarter thib ob. Txawm hais tias nkag mus rau "Jinjiu", tsis muaj kev hloov pauv hauv kev xav tau ntawm kev lag luam, thiab lub Hoobkas txiav txim siab ntau lawm raws li qhov xav tau.
Nyob rau hauv lub neej yav tom ntej, cov lag luam downstream feem ntau tos-thiab-pom, thiab lawv txaus siab los yuav cov xaj tshiab yog dav dav. Hauv qhov xwm txheej ntawm kev lag luam tsis muaj zog thiab kev nqis peev, ua npuas ncauj polyether "Jinjiu" tsis zoo txaus los txhaj qhov tseem ceeb rau hauv cov dej ntws.
