Thaum pib lub Plaub Hlis, hauv ib lub lis piam xwb, kev lag luam tus nqi ntawm cyclohexanone dhia los ntawm 900 yuan / tuj. Muaj ntau qhov laj thawj rau qhov dhia no. Seb qhov kev xav ntawm kev lag luam tuaj yeem nce ntxiv yog kev txhawj xeeb los ntawm kev ua lag luam.

Txij li thaum Lub Peb Hlis 30, kev lag luam tus nqi ntawm cyclohexanone tau nce siab heev. Tus nqi lag luam ntawm cyclohexanone nyob rau sab hnub tuaj Suav teb tau ntsib peb qhov kev nce ntawm 9,450 yuan / ton. Raws li kev kaw lub Plaub Hlis 7, tus nqi lag luam ntawm cyclohexanone nyob rau sab hnub tuaj Tuam Tshoj tau nce mus rau 10,350 yuan / ton. . Yog li cia peb txheeb xyuas lub sijhawm ntawm peb lub nthwv dej ntawm tus nqi nce ntxiv: thawj nthwv dej, Lub Peb Hlis 30, rub tawm 200 yuan / tuj. Qhov laj thawj feem ntau yog vim qhov nruj ntawm cov khoom muag ntawm lub khw. Shandong Hualu Hengsheng txo cov zis txhua hnub; Chongqing Huafeng cog kaw rau kev saib xyuas; Shanxi Yangmei Fengxi cyclohexanone cog kaw thiab kev saib xyuas xov xwm yog siv, kev lag luam ncig cov khoom siv nruj, cov khoom siv hauv Hoobkas tsis kam muag, thiab tus nqi ntawm cyclohexanone hauv East Tuam Tshoj kev lag luam tau nce 200 yuan / Tuj rau 9,650 yuan / tuj; lub thib ob nthwv dej, Plaub Hlis Ntuj 1, raws li Zhuo Chuang cov ntaub ntawv, Sinopec muag ntawm ntshiab benzene teev nqi nce los ntawm 150 yuan / ton, kev siv ntawm 6,500 yuan / ton, thiab Fengxi pib nce nqi txij nkawm. Eastern China cyclohexanone tau nce los ntawm 300 yuan / tuj rau 9950; thib peb nthwv dej, thaum lub Plaub Hlis 6, cov npe teev nqi ntawm Sinopec kev muag khoom ntawm cov ntshiab benzene tau nce ntxiv los ntawm 200 yuan / tuj, thiab kev siv ntawm 6,700 yuan / tuj, kev lag luam nruj yuav tsis hloov, thiab tus nqi yuav pab Push, kev lag luam tus nqi ntawm cyclohexanone tau nce ntxiv, thiab kev lag luam tus nqi ntawm cyclohexanone nyob rau sab hnub tuaj Tuam Tshoj tau nce los ntawm 400 yuan / tuj rau 10,350 yuan / ton. Hais txog cov nyiaj tau los, cov nyiaj tau los ntawm cyclohexanone kuj tau rov qab los tom qab tus nqi. Hauv cov ntsiab lus, kev lag luam tus nqi nce ntawm cyclohexanone yog nyob rau ntawm ib sab ntsig txog kev txhawb nqa ntawm lub khw muag khoom ntshiab benzene, thiab ntawm qhov tod tes, nws yog inseparable los ntawm kev thov kev txhawb nqa ntawm cov tshuaj fiber ntau.

Lub ntsiab downstream caprolactam kev lag luam ntawm cyclohexanone tau ua haujlwm nyob rau theem siab, thiab nws txuas ntxiv ruaj khov ntawm ntau dua 85%. Qhov kev thov rau cov khoom siv raw yog siab heev. Txawm li cas los xij, ib nrab ntawm cov chaw xa khoom tseem ceeb ntawm cyclohexanone tau kho dua, thiab cov khoom lag luam kev lag luam tau nruj.

Saib ntawm qhov kev xav ntawm kev ua lag luam, los ntawm qhov kev xav ntawm tus nqi, tuaj txog ntawm cov ntshiab benzene ntawm qhov chaw nres nkoj tseem ceeb tseem txwv. Los ntawm daim ntawv tshaj tawm shipping, qhov chaw nres nkoj tseem ceeb tseem mus rau lub tsev khaws khoom. Nrog rau kev txhim kho thiab kho kom zoo nyob rau lub Plaub Hlis, kev lag luam pib thauj khoom yuav tsum poob dua. Ntawm qhov kev thov sab, qhov pib load ntawm styrene kev lag luam yuav tsum txo qis, tab sis tom qab Sinochem Quanzhou thiab Tuam Tshoj Hiav Txwv Plhaub tau muab tso rau hauv ntau lawm, tag nrho cov kev thov tau nce. Yog li ntawd, cov ntshiab benzene tseem nyob rau hauv qhov sib npaug nruj, thiab kev saib xyuas yuav tsum tau them rau qhov cuam tshuam ntawm styrene tiam sis ntawm kev ua lag luam. Los ntawm cov khoom siv, kev saib xyuas ntawm Huafeng xav tias yuav xaus rau yav tom ntej, thiab kev saib xyuas ntawm Yangmei Fengxi cov cuab yeej xav tias yuav kav ntev li 20 hnub, thiab nws yuav tsum rov pib ua haujlwm puv sijhawm tom qab lub Tsib Hlis lig; lub Hualu Hengsheng ntaus ntawv yog down-loaded thiab lub sij hawm rov qab yuav tsum tau txiav txim. Hais txog kev thov, Shandong Haili tus thib ob caprolactam cog tau teem sijhawm pib lub Plaub Hlis 10 (txhawb). Pib txij lub Plaub Hlis 15, Cangzhou Xuyang Chemical's caprolactam tau teem sijhawm los kho dua li 10 hnub (txhawb nqa), thiab lub Plaub Hlis 20, Fujian Yongrong Technology, Nanjing Dongfang tau ua tiav rau kev kho dua tshiab, thiab kho dua tshiab rau 7 hnub thiab 40 hnub raws li. Tsis tas li ntawd, nyob ib ncig ntawm lub Plaub Hlis 20, Yangmei Fengxi xav tias yuav pib cov khoom qis los ntxiv cov khoom lag luam. Nws cia siab tias cov khoom siv nruj ntawm cyclohexanone yuav txuas ntxiv yam tsawg kawg kom txog rau thaum Lub Plaub Hlis 20 thiab pib yooj yim. Yog li ntawd, hauv cov ntsiab lus, cyclohexanone Cov kev nce qib ntawm kev lag luam tus nqi yuav nyob twj ywm tsawg kawg kom txog rau thaum lub Plaub Hlis Ntuj lig, thiab tos thiab pom qhov cuam tshuam ntawm kev hloov pauv hauv kev lag luam ntshiab benzene ntawm cyclohexanone.
