M'mawa pa Disembala 27, 2020, Mphotho 6 Zamakampani aku China, Mphotho Zoyamika ndi Nomination Awards zidalengezedwa. Baling Petrochemical's new caprolactam green production seti ya pulojekiti yatsopano yaukadaulo yapambana Mphotho ya China Industrial Award ndipo ndi gawo lokhalo lopambana la Sinopec. Mothandizidwa ndi Unduna wa Sayansi ndi Ukadaulo ndi Natural Science Foundation yaku China, Baling Petrochemical and Petrochemical Research Institute yasintha zotsatira za kafukufuku wasayansi zomwe zapezedwa pakufufuza koyambira muukadaulo watsopano. Pambuyo pa zaka 30, mibadwo itatu yagonjetsa zopinga zosawerengeka ndi masautso, idapanga umisiri wathunthu waumisiri wobiriwira wokhala ndi ufulu wodziyimira pawokha waluntha, idathyola bwino kulamulira kwakunja paukadaulo wopanga caprolactam kwa zaka 70, ndikukhazikitsa chifaniziro chaukadaulo waku China wodziyimira pawokha. Pakalipano, chiwerengero cha kudzidalira kwa caprolactam chakwera kuchokera ku 30% kufika ku 94%, ndipo kudalira kwa dziko langa pa teknoloji yachilendo ndi zinthu zotumizidwa kunja kwatsika kwambiri.

Zaka 1.30 za luso lodziyimira pawokha, zidapanga luso lathunthu laukadaulo watsopano wopanga caprolactam wobiriwira.

Caprolactam ndi chinthu chofunikira kwambiri chamankhwala. Monga monomer popanga ulusi wa nayiloni-6 ndi mapulasitiki opangira nayiloni-6, amagwiritsidwa ntchito kwambiri muzovala, magalimoto, zamagetsi ndi zina zomwe zimagwiritsa ntchito zida zatsopano zatsopano. Makampani a caprolactam amagwirizana kwambiri ndi mphamvu zachuma za dziko komanso momwe anthu amakhalira, ndipo ali ndi udindo waukulu pa chitukuko ndi kupititsa patsogolo chuma cha dziko.

Kumayambiriro kwa zaka za m'ma 1990, Sinopec idawononga pafupifupi yuan 10 biliyoni kuyambitsa ma seti 3 a matani 50,000 / chaka chopanga caprolactam, omwe adamangidwa ku Baling Petrochemical, Nanjing DSM Dongfang Chemical Co., Ltd. ndi Shijiazhuang Refinery. Pambuyo pake, bungwe la Sinopec linatenga luso lamakono la kupanga caprolactam-kukonza cyclohexanone oxime monga njira yopambana, ndikuchita umisiri watsopano wa teknoloji yobiriwira ya caprolactam ku Baling Petrochemical. Ndi thandizo lamphamvu la Unduna wa Sayansi ndi Ukadaulo ndi National Natural Science Foundation ya China, komanso chitsogozo cha Academician Min Enze ndi Academician Shu Xingtian wa China Academy of Sciences, gulu lofufuza lagwirizana moona mtima ndikugwira ntchito molimbika. M'zaka 30 zapitazi, ma patent opitilira 100 akunja ndi akunja apangidwa. Ukadaulo wathunthu waukadaulo watsopano wopangira zobiriwira za caprolactam zophatikizidwa ndi njira zatsopano zamachitidwe, zida zatsopano zothandizira komanso umisiri watsopano wamachitidwe apangidwa.

Matekinoloje atsopanowa ali ndi matekinoloje asanu ndi limodzi, onse omwe afika pamlingo wotsogola padziko lonse lapansi. Iwo ndi single-reactor mosalekeza slurry bed cyclohexanone ammoximation process technology kupanga cyclohexanone oxime, cyclohexanone oxime Beckman magawo atatu rearrangement luso, Ammonium sulfate neutralization crystallization teknoloji, magnetically stabilized bed caprolactam hydrorexiranges ukadaulo m luso , cyclohexene esterification hydrogenation kupanga ukadaulo watsopano wa cyclohexanone. Pakati pawo, teknoloji yoyamba ya 4 yakhala ikugwiritsidwa ntchito m'mafakitale, ndipo zovomerezeka za 137 zapakhomo ndi zakunja zapangidwa; Mphotho zokwana 17 zakuzigawo ndi za unduna zapambana, kuphatikiza mphotho imodzi yoyamba yaukadaulo wadziko lonse komanso mphotho yachiwiri imodzi yakupita patsogolo kwa sayansi ndiukadaulo.

Baling Petrochemical's "cyclohexanone oxime gas-phase rearrangement process of bed without by-product ammonium sulfate" yapitanso patsogolo pakukonzekera zothandizira, ukadaulo wamachitidwe, kuyenga kwazinthu, ndi zina zambiri, ndikumaliza kafukufuku waukadaulo wocheperako komanso woyendetsa ndege. 50,000 matani / chaka ntchito mafakitale. Kuphatikiza apo, Sinopec idachita upainiya wa "Cyclohexene Esterification Hydrogenation to Cyclohexanone New Process". Mlingo wogwiritsa ntchito atomu ya kaboni uli pafupi ndi 100%, yomwe singogwiritsa ntchito mphamvu zochepa chabe, komanso imatha kupanganso ethanol yamtheradi. Kafukufuku woyeserera wamalizidwa. 200,000 matani / chaka ndondomeko ndondomeko chitukuko, ndi 200,000 matani/chaka ntchito mafakitale idzachitika posachedwapa.

2.Tekinoloje yatsopano imayendetsa chitukuko champhamvu cha mafakitale atsopano, kusamutsa ndi kukweza kumateteza mtsinje wamadzi oyera.

Masiku ano, Baling Petrochemical wakhala lalikulu petrochemical ndi malasha mankhwala ophatikizana ogwira ntchito, komanso yaikulu m'banja caprolactam ndi lifiyamu mphira kupanga ogwira ntchito ndi yofunika epoxy utomoni kupanga m'munsi. Pakati pawo, unyolo wa mankhwala a caprolactam umaphatikizapo matani 500,000/chaka caprolactam (kuphatikiza matani 200,000), matani 450,000/chaka cyclohexanone, ndi matani 800,000/chaka ammonium sulfate. Kupanga kobiriwira kwa Caprolactam matekinoloje atsopano apita patsogolo kwambiri m'mafakitale azikhalidwe. Sikuti ndi wochezeka kwambiri ndi chilengedwe, mpweya woipa pamtundu uliwonse umachepetsedwa ndi 50%, ndipo mtengo wopanga wagawo umachepetsedwa ndi 50%, ndipo ndalama zopangira mphamvu pa matani 10,000 zimachepetsedwa kukhala zosakwana yuan miliyoni 150. Kuchepetsa pafupifupi 80% kwabweretsa phindu lalikulu pazachuma komanso chikhalidwe cha anthu.

Ukadaulo watsopano wa kupanga caprolactam wobiriwira walimbikitsa kwambiri chitukuko chofulumira cha caprolactam ndi mafakitale ake akumunsi. Pofika kumapeto kwa 2019, Sinopec yamanga malo opangira ma caprolactam angapo ku Baling Petrochemical, Zhejiang Baling Hengyi ndi makampani ena, ndikupanga matani 900. 24.39 peresenti. Pakali pano, dziko langa wobiriwira caprolactam kupanga mphamvu yafika matani 4 miliyoni, kukhala sewerolo lalikulu kwambiri padziko lonse lapansi, ndi gawo lonse msika wa pa 50%, kupanga 40 biliyoni yuan akutuluka makampani, ndi kuyendetsa chitukuko amphamvu 400 biliyoni kutsika mafakitale.

Mu 2020, Baling Petrochemical's caprolactam industry relocation and upgrading development project ndi ndalama zokwana 13.95 biliyoni za yuan zidzakhazikitsidwa ku Hunan Yueyang Green Chemical Industrial Park. Pulojekitiyi imagwiritsa ntchito matekinoloje atsopano opangidwa mwaokha ndi Sinopec kuti amange tcheni cha mafakitale a caprolactam a 600,000/chaka. Ntchitoyi idzamangidwa ngati pulojekiti yowonetsera komanso pulojekiti yowonetsera "kuteteza mtsinje ndi madzi abwino", kuphwanya "chizindikiro cha mankhwala a mtsinje", ndikukhazikitsanso mabizinesi opangira mankhwala owopsa m'matauni omwe ali ndi anthu ambiri m'dziko lonselo. .
