Txog li 3 hnub, kev lag luam hauv tsev acetic acid ruaj khov thiab ruaj khov.Raws li tag nrho, cov nqi ntawm tag nrho cov 2 hnub muaj zog dua li tus nqi nruab nrab tau nce lub lim tiam dhau los.Cov khoom lag luam tag nrho tseem nruj, tus nqi ntawm cov chaw lag luam muaj kev muag khoom tseem tsis tshua muaj vim muaj ntau qhov kev txiav txim, qhov kev thov qis qis yog ruaj khov, cov nqi lag luam muaj zog.

Thaum Lub Kaum Ib Hlis 3, tus nqi siv hauv Jiangsu kev ua lag luam yog 2,700-2,800 yuan / ton, tsis hloov los ntawm yav dhau los siab ntawm 2,700-2,800 yuan / ton rau lub Kaum Ib Hlis 2.Tus nqi siv nyob rau sab qab teb Tuam Tshoj ua lag luam yog 2750-2800 yuan / ton, uas yog tib yam li tus nqi siab dhau los (Lub Ob Hlis 17) ntawm lub xyoo no.

Tam sim no, cov nroj tsuag hauv tsev acetic acid pib smoothly.Cov nroj tsuag tau khiav ib txwm, thiab kev khiav hauj lwm tus nqi yog tswj ntawm qib siab ntawm 95%.Kev ua haujlwm siab tsis tau ua rau lub siab ntawm cov khoom siv.Lub tuam txhab kev xa khoom tau ua tiav zoo thiab cov khoom muag tseem nyob rau theem qis.

Thaum kawg ntawm Lub Kaum Hli, cov khoom lag luam glacial acetic acid cov khoom lag luam txuas ntxiv poob qis.East Tuam Tshoj, cov khoom lag luam poob qis me ntsis, kev lag luam xa khoom tau zoo.In central Tuam Tshoj, cov khoom muag tau pib poob, thiab qhov poob loj tshaj plaws, qee lub lag luam cov khoom muag tsis txaus. , coj kev muag khoom tsawg.Jin-ji cheeb tsam, cov khoom muag pib nce, tab sis tag nrho cov khoom xa tuaj kuj sai dua.Shandong cheeb tsam, cov khoom muag txuas ntxiv txo, kev muag khoom smooth.Kev lag luam cov khoom lag luam nyob rau sab qaum teb hnub poob ntawm Tuam Tshoj txuas ntxiv poob. Cov khoom muag nyob rau sab qab teb sab hnub poob tau tiaj tus los ntawm lub lim tiam dhau los.

Tag nrho cov khoom muag hauv tsev tau poob 12.44 feem pua ​​​​piv rau lub Kaum Hlis 19.

Raws li lub Kaum Ib Hlis 3, acetic acid downstream khoom lag luam ruaj khov tiav.Lub ethyl acetate kev ua lag luam nyob hauv kev lag luam ruaj khov thiab tau nce txhua txoj hauv kev thaum ntxov.Tus nqi tam sim no nyob rau theem siab, cov khoom lag luam ntawm cov khoom lag luam tsis ntau, tab sis qhov kev tsav tsheb ntawm tus nqi tiaj tus tsis txaus, thiab qhov qis qis qis qis qis qis qis qis qis dua cov txheej txheem nce ntxiv.Lub lag luam butyl acetate ruaj khov thiab muag muag, raw khoom nto tag nrho tau ploj mus, lub lag luam shipping yog ncaj ncees, downstream tau txais huab cua tsis zoo, lub zuag qhia tag nrho kev ua lag luam yog tsis muaj zog.Lub acetic acid butyl ester kev lag luam yog ruaj khov, lub mov sab yog nce txaus, kev xav ntawm kev lag luam. lub downstream, thawb kom tsis muaj zog.Vinyl acetate kev ua lag luam yog ruaj khov, nyob rau hauv cov ntaub ntawv ntawm kev them nyiaj yug muaj zog, tsis muaj mov, kev ua lag luam khiav muaj zog.Vinegar anhydride kev lag luam stability pom nce, cuam tshuam los ntawm yankuang khoom overhaul, kev lag luam khoom tsis ntau. , downstream huab cua yog qhov ncaj ncees, kev lag luam sib txawv muaj zog.

Nyob rau hauv lub sij hawm tom qab, nyob rau hauv cov nqe lus ntawm cov khoom, txawm hais tias manufacturers tuav ib tug siab kev khiav hauj lwm tus nqi, cov ndlwg ntawm cov khoom yog du, thiab lub siab ntawm enterprise cov khoom muag yuav luag tsis muaj nyob.Nws cia siab tias cov khoom lag luam nyob rau lub sijhawm tom ntej tseem yuav muaj txiaj ntsig zoo.Ntawm qhov kev thov sab, tom qab "Silver Decade", qhov kev xav ntawm cov lag luam downstream tseem nyob ruaj khov, thiab cov neeg thov txawv teb chaws tuaj tos, thiab sab xa tawm tuaj yeem pom muaj kev lag luam rov qab.Lub lag luam acetic acid yuav tsum tau khiav mus rau yav tom ntej.
