Thaum sawv ntxov ntawm lub Kaum Ob Hlis 27, 2020, qhov khoom plig thib 6 ntawm Tuam Tshoj Kev Lag Luam Khoom Plig, Khoom Plig Qhuas thiab Khoom Plig Nomination tau tshaj tawm. Baling Petrochemical txoj kev tsim khoom tshiab caprolactam ntsuab tiav cov txheej txheem thev naus laus zis tshiab tau yeej qhov khoom plig Tuam Tshoj Kev Lag Luam Khoom Plig thiab yog tib lub chaw tau txais khoom plig ntawm Sinopec. Nrog kev txhawb nqa ntawm Ministry of Science thiab Technology thiab Natural Science Foundation ntawm Tuam Tshoj, Baling Petrochemical thiab Petrochemical Research Institute tau hloov cov txiaj ntsig kev tshawb fawb tau txais los ntawm kev tshawb fawb yooj yim mus rau hauv cov thev naus laus zis tshiab. Tom qab 30 xyoo, peb tiam neeg tau kov yeej ntau qhov kev poob qis thiab kev txom nyem, tsim cov txheej txheem thev naus laus zis ntsuab nrog cov cai ywj pheej ntawm kev txawj ntse, ua tiav kev rhuav tshem kev tswj hwm txawv teb chaws ntawm cov thev naus laus zis tsim khoom caprolactam rau 70 xyoo, thiab tsim kom muaj lub npe ntawm Tuam Tshoj txoj kev tsim kho tshiab ywj pheej. Tam sim no, tus nqi caprolactam kev txaus siab rau tus kheej hauv tsev tau nce ntawm 30% mus rau 94%, thiab kuv lub teb chaws vam khom cov thev naus laus zis txawv teb chaws thiab cov khoom xa tuaj tau poob qis heev.

1.30 xyoo ntawm kev tsim kho tshiab ywj pheej, ua tiav tsim cov txheej txheem tshiab rau kev tsim cov caprolactam ntsuab

Caprolactam yog ib qho khoom siv tseem ceeb hauv cov tshuaj lom neeg. Ua ib qho monomer rau kev tsim cov nylon-6 synthetic fibers thiab nylon-6 engineering plastics, nws yog siv dav hauv textiles, tsheb, electronics thiab lwm yam teb uas siv cov ntaub ntawv tshiab rau kev tsim kho tshiab. Kev lag luam caprolactam muaj feem cuam tshuam nrog lub teb chaws lub zog kev lag luam thiab cov neeg lub neej, thiab nyob hauv txoj haujlwm tseem ceeb hauv kev txhim kho thiab kev txhim kho tas mus li ntawm lub teb chaws kev lag luam.

Thaum xyoo 1990s thaum ntxov, Sinopec siv ze li ntawm 10 billion yuan los tsim 3 pawg ntawm 50,000 tons / xyoo caprolactam ntau lawm, uas tau tsim hauv Baling Petrochemical, Nanjing DSM Dongfang Chemical Co., Ltd. thiab Shijiazhuang Refinery. Tom qab ntawd, lub koom haum Sinopec tau siv cov thev naus laus zis tseem ceeb ntawm kev tsim caprolactam - kev npaj ntawm cyclohexanone oxime ua qhov kev tawg, thiab ua tiav cov txheej txheem tshiab rau kev tsim caprolactam ntsuab ntawm Baling Petrochemical. Nrog kev txhawb nqa zoo ntawm Ministry of Science thiab Technology thiab National Natural Science Foundation ntawm Tuam Tshoj, thiab kev taw qhia ntawm Academician Min Enze thiab Academician Shu Xingtian ntawm Suav Academy of Sciences, pab pawg tshawb fawb tau koom tes thiab ua haujlwm hnyav. Hauv 30 xyoo dhau los, ntau dua 100 daim ntawv pov thawj tsim khoom hauv tsev thiab txawv teb chaws tau tsim. Ib pawg ntawm cov thev naus laus zis tshiab rau kev tsim caprolactam ntsuab sib xyaw ua ke los ntawm cov txheej txheem tshuaj tiv thaiv tshiab, cov ntaub ntawv catalytic tshiab thiab kev tsim kho tshuaj tiv thaiv tshiab tau tsim.

Cov txheej txheem tshiab no muaj rau lub hauv paus thev naus laus zis, txhua yam tau mus txog qib siab thoob ntiaj teb. Lawv yog cov txheej txheem ib leeg-reactor txuas ntxiv slurry txaj cyclohexanone ammoximation txheej txheem thev naus laus zis los tsim cyclohexanone oxime, cyclohexanone oxime Beckman peb-theem rearrangement thev naus laus zis, Ammonium sulfate neutralization crystallization thev naus laus zis, magnetically stabilized txaj caprolactam hydrorefining thev naus laus zis, cyclohexanone oxime roj theem rearrangement los tsim caprolactam thev naus laus zis, cyclohexene esterification hydrogenation los tsim cyclohexanone tshiab thev naus laus zis. Ntawm lawv, thawj 4 thev naus laus zis tau siv rau hauv kev lag luam, thiab 137 daim ntawv pov thawj tsim khoom hauv tsev thiab txawv teb chaws tau tsim; 17 lub xeev thiab ministry khoom plig tau yeej, suav nrog 1 qhov khoom plig thawj zaug rau kev tsim khoom siv hauv tebchaws thiab 1 qhov khoom plig thib ob rau kev nce qib hauv tebchaws thiab kev tshawb fawb thiab thev naus laus zis.

Baling Petrochemical's "cyclohexanone oxime gas-phase rearrangement moving bed process without by-product ammonium sulfate" kuj tau ua tiav kev vam meej hauv kev npaj catalyst, kev siv tshuab ua tshuaj, kev ua kom cov khoom zoo, thiab lwm yam, thiab ua tiav kev tshawb fawb me me thiab kev sim ua haujlwm. 50,000 tons/xyoo kev siv hauv kev lag luam. Tsis tas li ntawd, Sinopec tau tsim "Cyclohexene Esterification Hydrogenation to Cyclohexanone New Process". Tus nqi siv carbon atom ze li ntawm 100%, uas tsis yog tsuas yog siv hluav taws xob tsawg xwb, tab sis kuj tuaj yeem tsim cov ethanol tag nrho. Kev tshawb fawb sim tau ua tiav. 200,000 tons/xyoo kev tsim cov txheej txheem, thiab 200,000 tons/xyoo kev siv hauv kev lag luam yuav raug ua sai sai no.

2. Cov thev naus laus zis tshiab tsav tsheb txoj kev loj hlob ntawm cov lag luam tshiab, kev tsiv chaw thiab kev txhim kho kom zoo dua qub tiv thaiv tus dej ntshiab

Niaj hnub no, Baling Petrochemical tau dhau los ua ib lub tuam txhab loj hauv kev lag luam petrochemical thiab thee, nrog rau lub tuam txhab tsim cov roj hmab caprolactam thiab lithium loj tshaj plaws hauv tebchaws thiab yog lub hauv paus tseem ceeb rau kev tsim cov roj hmab epoxy. Ntawm lawv, cov khoom lag luam caprolactam suav nrog 500,000 tons / xyoo caprolactam (suav nrog kev koom tes ua lag luam 200,000 tons), 450,000 tons / xyoo cyclohexanone, thiab 800,000 tons / xyoo ammonium sulfate. Caprolactam ntsuab tsim cov txheej txheem tshiab tau ua tiav kev nce qib hauv kev lag luam ib txwm muaj. Tsis yog nws tsuas yog zoo rau ib puag ncig xwb, cov pa phem ib yam khoom raug txo los ntawm 50%, thiab tus nqi tsim khoom raug txo los ntawm 50%, thiab kev nqis peev hauv peev xwm tsim khoom ib 10,000 tons raug txo kom tsawg dua 150 lab yuan. Kev txo qis yuav luag 80% tau tsim cov txiaj ntsig zoo rau kev lag luam thiab kev sib raug zoo.

Cov thev naus laus zis tshiab ntawm kev tsim cov tshuaj caprolactam ntsuab tau txhawb nqa kev loj hlob sai ntawm caprolactam thiab nws cov lag luam downstream. Txog rau thaum kawg ntawm xyoo 2019, Sinopec tau tsim ntau lub chaw tsim khoom caprolactam hauv Baling Petrochemical, Zhejiang Baling Hengyi thiab lwm lub tuam txhab, nrog rau qhov ntsuas ntau lawm ntawm 900,000 tons / xyoo, suav txog 12.16% ntawm lub peev xwm tsim khoom caprolactam thoob ntiaj teb thiab lub peev xwm tsim khoom caprolactam hauv tsev ntawm 24.39%. Tam sim no, kuv lub teb chaws lub peev xwm tsim khoom caprolactam ntsuab tau mus txog 4 lab tons, dhau los ua tus tsim khoom loj tshaj plaws hauv ntiaj teb, nrog rau kev lag luam thoob ntiaj teb ntawm ntau dua 50%, tsim kom muaj kev lag luam tshiab 40 billion yuan, thiab tsav tsheb kev loj hlob ntawm 400 billion kev lag luam downstream.

Xyoo 2020, Baling Petrochemical txoj kev tsim kho thiab txhim kho cov saw hlau caprolactam nrog tag nrho cov peev txheej ntawm 13.95 billion yuan yuav pib ua haujlwm hauv Hunan Yueyang Green Chemical Industrial Park. Txoj haujlwm no siv cov thev naus laus zis tshiab uas Sinopec tsim los ntawm nws tus kheej los tsim kom muaj 600,000-ton / xyoo caprolactam industrial saw hlau. Txoj haujlwm no yuav raug tsim ua ib qho project qhia thiab ib qho project benchmark rau "kev tiv thaiv tus dej thiab dej ntshiab", rhuav tshem "kev ncig ntawm tus dej tshuaj", thiab siv kev tsiv chaw ntawm cov chaw tsim tshuaj lom neeg txaus ntshai hauv cov nroog uas muaj neeg nyob coob thoob plaws lub tebchaws.
