Kev hloov pauv ntawm acetone kev ua lag luam nyob rau lub Yim Hli yog lub ntsiab lus tseem ceeb, thiab tom qab muaj kev nce siab hauv lub Xya Hli, cov kev lag luam tseem ceeb tau tswj hwm kev ua haujlwm siab nrog kev txwv tsis pub dhau. Dab tsi ntawm kev lag luam tau mloog zoo rau lub Cuaj Hli?

Thaum lub Yim Hli thaum ntxov, cov khoom thauj tuaj txog ntawm qhov chaw nres nkoj raws li tau npaj tseg, thiab cov khoom lag luam chaw nres nkoj tau nce ntxiv. Daim ntawv cog lus tshiab xa khoom, phenol ketone Hoobkas tawm, Shenghong Refining thiab Tshuaj yuav tsis tswj xyuas ib ntus, thiab kev lag luam xav tau nyob rau hauv siab. Kev xa khoom ntawm cov khoom muag tau nce, thiab cov neeg tuav tau xa khoom ntawm tus nqi qis. Lub davhlau ya nyob twg yog digesting cov ntawv cog lus thiab tos ntawm sidelines.
Nyob rau hauv nruab nrab Lub Yim Hli, kev lag luam hauv paus tsis muaj zog, nrog cov neeg tuav khoom xa khoom raws li kev lag luam thiab kev thov txwv los ntawm cov chaw tsim khoom kawg. Tsis muaj ntau qhov kev tshaj tawm, cov tuam txhab petrochemical tau txo qis tus nqi ntawm acetone, nce nyiaj siab, thiab nce kev tos-thiab-pom kev xav.
Thaum kawg ntawm Lub Yim Hli, raws li hnub sib hais los txog, lub siab ntawm cov khoom cog lus hauv tsev tau nce, thiab kev xa khoom xa tuaj tau nce, ua rau muaj kev poob qis hauv kev muab. Cov khoom lag luam hauv chaw nres nkoj tsis txaus, thiab cov khoom lag luam ntshuam muab cov nqi qis thiab tsis muaj zog, nrog kev ruaj khov. Cov khoom siv hauv tsev thiab chaw nres nkoj sib tw hnyav, nrog cov chaw ua haujlwm hauv chaw nres tsheb zom cov khoom muag thiab nce cov nqi qis. Cov lag luam hauv qab txuas ntxiv mus ntxiv, ua rau muaj kev lag luam ua lag luam thiab kev lag luam tiaj tus.
Tus nqi sab: Tus nqi lag luam ntawm cov ntshiab benzene feem ntau yog nce, thiab cov khoom lag luam ntawm cov nroj tsuag ntshiab benzene ruaj khov. Raws li lub sijhawm xa khoom mus txog, tej zaum yuav muaj luv luv. Txawm hais tias qee qhov kev thov qis qis yuav tsum nce ntxiv, qhov no tsuas yog me ntsis rov qab los tom qab qhov kev poob qis hauv tag nrho cov kev xav tau qis. Yog li ntawd, txawm hais tias kev thov yuav rov qab me ntsis, tus nqi siv rau cov ntshiab benzene hauv lub sijhawm luv luv yuav nyob ib puag ncig 7850-7950 yuan / ton.
Tus nqi ntawm propylene nyob rau hauv kev ua lag luam tseem pheej poob qis, thiab tus nqi ntawm propylene poob sai sai, txo qhov siab ntawm kev ua lag luam thiab kev thov. Nyob rau hauv lub sij hawm luv luv, muaj tsawg chav rau tus nqi ntawm propylene poob. Tus nqi ntawm propylene nyob rau hauv lub lag luam Shandong tseem ceeb yuav tsum hloov pauv ntawm 6600 txog 6800 yuan / tuj.

Kev khiav hauj lwm tus nqi: Lub Hnub Qub Blue Harbin Phenol Ketone Plant tau npaj yuav rov pib ua ntej lub hli kawg, thiab Jiangsu Ruiheng Phenol Ketone Plant kuj tau npaj rov pib dua. Kev txhawb nqa Phase II Bisphenol A tsob nroj tuaj yeem muab tso rau hauv kev tsim khoom, uas yuav txo qis kev muag khoom ntawm acetone. Nws tau tshaj tawm tias 480000 ton / xyoo phenol ketone cog ntawm Changchun Chemical yog teem rau kev kho nyob rau nruab nrab mus rau lub Cuaj Hli Ntuj lig, thiab xav tias yuav kav ntev li 45 hnub. Txawm hais tias 650000 ton / xyoo cog ntawm Dalian Hengli yuav muab tso rau hauv kev ua haujlwm raws li tau teem tseg nyob rau nruab nrab mus rau lub Cuaj Hli Ntuj tau nyiam ntau yam. Kev tsim tawm ntawm nws cov kev txhawb nqa bisphenol A thiab isopropanol units yuav cuam tshuam ncaj qha rau kev muag khoom ntawm acetone. Yog tias cov nroj tsuag phenol ketone tau muab tso rau hauv kev ua haujlwm raws li qhov tau npaj tseg, txawm hais tias nws qhov kev pab cuam rau acetone hauv lub Cuaj Hli yog txwv, yuav muaj kev nce ntxiv hauv cov khoom siv tom qab.
Kev thov sab: Ua tib zoo saib xyuas cov xwm txheej ntawm cov khoom siv bisphenol A thaum lub Cuaj Hli. Lub sijhawm thib ob ntawm bisphenol A ntaus ntawv hauv Jiangsu Ruiheng yog npaj yuav muab tso rau hauv kev ua haujlwm, thiab rov pib dua ntawm Nantong Xingchen ntaus ntawv kuj yuav tsum tau saib xyuas. Rau MMA, vim muaj cov khoom siv tsawg, Shandong Hongxu's MMA ntaus ntawv yuav tsum txo qis ntau lawm. Liaoning Jinfa cov cuab yeej tau teem sijhawm los kho lub Cuaj Hli, thiab qhov xwm txheej tshwj xeeb tseem xav tau kev saib xyuas ntxiv. Raws li rau isopropanol, tam sim no tsis muaj cov phiaj xwm saib xyuas meej thiab muaj qee qhov kev hloov pauv rau lub cuab yeej. Rau MIBK, Wanhua Chemical's 15000 ton / xyoo MIBK cog yog nyob rau hauv lub xeev kaw thiab npaj yuav rov pib dua thaum lub Cuaj Hli; Lub 20000 tuj / xyoo cog hauv Zhenyang, Zhejiang tau teem sijhawm rau kev saib xyuas hauv lub Cuaj Hli, thiab lub sijhawm tshwj xeeb tseem yuav tsum tau ua raws.
Hauv cov ntsiab lus, kev ua lag luam acetone hauv lub Cuaj Hli yuav tsom mus rau kev hloov pauv ntawm cov khoom siv thiab cov qauv xav tau. Yog tias cov khoom siv nruj, nws yuav ua rau tus nqi ntawm acetone nce, tab sis nws tseem yuav tsum tau them sai sai rau cov kev hloov pauv ntawm qhov xav tau.
