Thaum pib lub Plaub Hlis, tsuas yog ib lub lim tiam xwb, tus nqi lag luam ntawm cyclohexanone tau dhia los ntawm 900 yuan / ton. Muaj ntau yam ua rau qhov kev dhia no. Seb qhov kev cia siab ntawm kev ua lag luam puas tuaj yeem nce ntxiv yog qhov txhawj xeeb los ntawm kev ua lag luam.

Txij li thaum Lub Peb Hlis 30, tus nqi lag luam ntawm cyclohexanone tau rov qab zoo heev. Tus nqi lag luam ntawm cyclohexanone hauv Sab Hnub Tuaj Suav Teb tau ntsib peb nthwv dej ntawm kev nce ntxiv los ntawm 9,450 yuan / ton. Txog rau thaum kaw ntawm Lub Plaub Hlis 7, tus nqi lag luam ntawm cyclohexanone hauv Sab Hnub Tuaj Suav Teb tau nce mus txog 10,350 yuan / ton. . Yog li cia peb tshuaj xyuas cov sijhawm ntawm peb nthwv dej tom ntej ntawm kev nce nqi: thawj nthwv dej, Lub Peb Hlis 30, rub tau 200 yuan / ton. Qhov laj thawj yog vim muaj kev muab khoom nruj ntawm kev ua lag luam. Shandong Hualu Hengsheng txo qis txhua hnub; Chongqing Huafeng cog kaw rau kev txij nkawm; Shanxi Yangmei Fengxi cyclohexanone cog kaw thiab xov xwm txij nkawm tau siv, kev muab khoom lag luam raug nruj, kev muab khoom ntawm lub Hoobkas tsis kam muag, thiab tus nqi ntawm cyclohexanone hauv Sab Hnub Tuaj Suav Teb kev ua lag luam tau nce los ntawm 200 yuan / Ton mus rau 9,650 yuan / ton; nthwv dej thib ob, Lub Plaub Hlis 1, raws li Zhuo Chuang Cov Ntaub Ntawv, Sinopec kev muag khoom ntawm cov benzene ntshiab teev cov nqi nce los ntawm 150 yuan / ton, kev siv ntawm 6,500 yuan / ton, thiab Fengxi pib nce cov nqi txij nkawm. Sab Hnub Tuaj Tuam Tshoj cyclohexanone nce los ntawm 300 yuan / ton mus rau 9950; nthwv dej thib peb, rau Lub Plaub Hlis 6, tus nqi teev ntawm Sinopec kev muag khoom ntawm cov benzene ntshiab tau tsa dua los ntawm 200 yuan / ton, thiab kev siv ntawm 6,700 yuan / ton, qhov xwm txheej nruj ntawm kev ua lag luam yuav tsis hloov pauv, thiab tus nqi yuav pab thawb, tus nqi ua lag luam ntawm cyclohexanone tau nce dua, thiab tus nqi ua lag luam ntawm cyclohexanone hauv Sab Hnub Tuaj Tuam Tshoj tau nce los ntawm 400 yuan / ton mus rau 10,350 yuan / ton. Hauv cov nqe lus ntawm cov nyiaj tau los, qhov nyiaj tau los ntawm cyclohexanone kuj tau rov qab los tom qab tus nqi. Hauv kev xaus, qhov kev nce nqi ntawm kev ua lag luam ntawm cyclohexanone yog ntawm ib sab tes cuam tshuam nrog kev txhawb nqa ntawm kev ua lag luam benzene ntshiab, thiab ntawm qhov tod tes, nws tsis tuaj yeem sib cais los ntawm kev txhawb nqa kev thov ntawm kev ua lag luam tshuaj fiber.

Lub lag luam caprolactam tseem ceeb ntawm cyclohexanone tau ua haujlwm ntawm qib siab, thiab nws tseem ruaj khov ntawm ntau dua 85%. Qhov kev thov rau cov khoom siv raw yog siab. Txawm li cas los xij, ib nrab ntawm cov chaw tsim khoom xa tawm tseem ceeb ntawm cyclohexanone tau kho dua tshiab, thiab kev muab khoom ntawm kev ncig ua lag luam tau nruj dua.

Saib ntawm qhov kev lag luam, los ntawm qhov kev xav ntawm tus nqi, qhov tuaj txog ntawm benzene ntshiab ntawm qhov chaw nres nkoj tseem tsawg. Los ntawm daim ntawv qhia kev xa khoom, qhov chaw nres nkoj tseem mus rau lub tsev rau khoom. Nrog rau kev nce ntxiv ntawm kev saib xyuas thiab kho hauv lub Plaub Hlis, qhov kev lag luam pib thauj khoom yuav poob dua. Ntawm sab kev thov, qhov pib thauj khoom ntawm kev lag luam styrene yuav txo qis, tab sis tom qab Sinochem Quanzhou thiab China Sea Shell raug muab tso rau hauv kev tsim khoom, qhov kev thov tag nrho tau nce ntxiv. Yog li ntawd, benzene ntshiab tseem nyob hauv qhov sib npaug nruj, thiab yuav tsum tau them sai sai rau qhov cuam tshuam ntawm cov qauv styrene ntawm kev ua lag luam. Los ntawm sab kev muab khoom, kev saib xyuas ntawm Huafeng yuav xaus rau yav tom ntej, thiab kev saib xyuas ntawm Yangmei Fengxi ntaus ntawv yuav kav ntev li 20 hnub, thiab nws yuav rov pib dua tag nrho cov khoom thauj tom qab lub Tsib Hlis lig; lub cuab yeej Hualu Hengsheng raug rub tawm thiab lub sijhawm rov qab yuav tsum txiav txim siab. Hauv qhov kev thov, Shandong Haili lub Hoobkas caprolactam thib ob tau teem sijhawm pib rau lub Plaub Hlis 10 (txhawb nqa). Txij li thaum Lub Plaub Hlis 15, Cangzhou Xuyang Chemical's caprolactam tau teem sijhawm kom kho dua li 10 hnub (txhawb nqa), thiab thaum Lub Plaub Hlis 20, Fujian Yongrong Technology, Nanjing Dongfang tau nres kho dua, thiab kho dua 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 lub nra hnyav kom rov ua kom muaj kev lag luam. Nws xav tias qhov kev muab khoom nruj ntawm cyclohexanone yuav txuas ntxiv mus txog rau Lub Plaub Hlis 20 thiab pib yooj yim dua. Yog li ntawd, hauv kev xaus, cyclohexanone Qhov kev nce nqi ntawm cov nqi lag luam yuav nyob tsawg kawg yog txog rau thaum kawg Lub Plaub Hlis, thiab tos thiab saib qhov cuam tshuam ntawm kev hloov pauv hauv kev lag luam benzene ntshiab ntawm cyclohexanone.
