Subaxnimadii Diseembar 27, 2020, waxaa lagu dhawaaqay Abaalmarinnada Warshadaha Shiinaha ee 6aad, Abaalmarinta Ammaanta iyo Abaalmarinta Magacaabista. Baling Petrochemical's wax soo saarka cagaaran ee caprolactam cusub oo dhammaystiran ee mashruuca tignoolajiyada cusub ayaa ku guulaystay Abaalmarinta Warshadaha Shiinaha waana qaybta kaliya ee ku guulaysata abaal-marinaha Sinopec. Iyada oo taageero laga helayo Wasaaradda Sayniska iyo Teknolojiyadda iyo Aasaaska Sayniska Dabiiciga ah ee Shiinaha, Baling Petrochemical iyo Machadka Cilmi-baarista Petrochemical ayaa beddelay natiijooyinka cilmi-baarista sayniska ee laga helay cilmi-baarista aasaasiga ah ee tignoolajiyada cusub. 30 sano ka dib, saddex jiil ayaa ka adkaaday dib u dhacyo iyo dhibaatooyin aan la tirin karin, horumariyo set dhamaystiran oo teknoolajiyada cagaaran leh xuquuqda hantida aqooneed madax-bannaan, si guul leh u jebiyey monoboli shisheeye on technology wax soo saarka caprolactam muddo 70 sano ah, oo la aasaasay image brand ee technology hal-abuurka madax banaan ee Shiinaha. Waqtigan xaadirka ah, heerka isku-filnaanshaha 'caprolactam' ee gudaha wuxuu ka kacay 30% ilaa 94%, iyo ku tiirsanaanta waddankeyga ku tiirsanaanta tignoolajiyada shisheeye iyo badeecadaha dibadda laga keeno ayaa aad hoos ugu dhacay.

1.30 sano oo hal-abuurnimo madax-bannaan, ayaa si guul leh u horumarisay tikniyoolajiyad dhammaystiran oo cusub oo loogu talagalay soosaarka cagaaran ee caprolactam

Caprolactam waa walxo kiimiko ah oo ceeriin ah oo muhiim ah. Sida monomer loogu talagalay soo saarista naylon-6 fiilooyinka synthetic iyo nylon-6 balaastikada injineernimada, waxaa si weyn loogu isticmaalaa dunta, baabuurta, qalabka elektaroonigga ah iyo meelaha kale ee isticmaala qalab cusub oo loogu talagalay hal-abuurka. Warshadaha caprolactam waxay si dhow ula xidhiidhaan xoogga dhaqaale ee dalka iyo heerka nolosha dadka, waxayna boos muhiim ah ka hayaan horumarinta iyo horumarinta joogtada ah ee dhaqaalaha qaranka.

Horraantii 1990-meeyadii, Sinopec waxay ku bixisay ku dhawaad ​​10 bilyan yuan si ay u soo bandhigto 3 qaybood oo ah 50,000 tons/sanad dhirta wax soo saarka kaprolactam, kuwaas oo lagu dhisay Baling Petrochemical, Nanjing DSM Dongfang Chemical Co., Ltd. iyo Shijiazhuang Sifeynta. Intaa ka dib, ururka Sinopec wuxuu qaatay tignoolajiyada asaasiga ah ee wax-soo-saarka caprolactam-diyaarinta cyclohexanone oxime sidii horumar, wuxuuna fuliyay tignoolajiyada cusub oo dhamaystiran oo loogu talagalay soosaarka caprolactam cagaaran ee Baling Petrochemical. Iyada oo taageero xooggan laga helayo Wasaaradda Sayniska iyo Tignoolajiyada iyo Mu'asasada Sayniska Dabiiciga ah ee Qaranka ee Shiinaha, iyo hagida Academician Min Enze iyo Academician Shu Xingtian oo ka tirsan Akadeemiyada Sayniska Shiinaha, kooxda cilmi-baarista ayaa si daacad ah u wada shaqeeyay oo si adag u shaqeeyay. 30kii sano ee la soo dhaafay, in ka badan 100 shati-hal-abuur oo gudaha iyo dibadda ah ayaa la sameeyay. Tiknoolajiyada cusub ee wax soo saarka cagaaran ee kaprolactam oo lagu daray dariiqyo falcelin cusub, qalab cusub oo kicinta iyo injineernimada falcelinta cusub ayaa la sameeyay.

Qalabkan cusub ee tignoolajiyada cusubi wuxuu leeyahay lix tignoolajiyada aasaasiga ah, kuwaas oo dhamaantood gaadhay heerka hogaaminta caalamiga ah. Waxay yihiin hal-reactor joogto ah sariirta sariirta cyclohexanone ammoximation tikniyoolajiyada si loo soo saaro cyclohexanone oxime, cyclohexanone oxime Beckman tignoolajiyada dib-u-habaynta saddex-heer, Tiknoolajiyada dhexdhexaadinta Ammonium sulfate, tignoolajiyada sariirta sariirta ee caprolactam hydrorefining magnetically xasilan oo soo saarta tignoolajiyada caprolactam hydrorefining , cyclohexene esterification hydrogenation si ay u soo saaraan cyclohexanone technology cusub. Waxaa ka mid ah, 4 tignoolajiyada ugu horreeya ayaa lagu dabaqay warshado, waxaana la sameeyay 137 shati-hal-abuur oo gudaha iyo dibedda ah; 17 abaal-marin oo heer gobol iyo heer wasiir ah ayaa lagu guuleystay, oo ay ku jiraan 1 abaal-marinta koowaad ee hal-abuurka tignoolajiyada qaranka iyo 1 abaal-marin labaad oo loogu talagalay horumarka sayniska iyo tignoolajiyada qaranka.

Baling Petrochemical's "Cyclohexanone oxime gaaska-wejiga dib u habeynta habraaca sariirta guuraya iyada oo aan la soo saarin ammonium sulfate" ayaa sidoo kale horumar horumarsan ka samaysay diyaarinta kicinta, tignoolajiyada falcelinta, sifaynta alaabta, iwm., waxayna dhamaystirtay cilmi baadhisyo tiro yar iyo tijaabo tijaabo ah. Codsiga warshadaha 50,000 tan / sanad. Intaa waxaa dheer, Sinopec waxay hormuud ka ahayd "Cyclohexene Esterification Hydrogenation to Cyclohexanone Process New". Heerka isticmaalka atamka kaarboon wuxuu ku dhow yahay 100%, kaas oo aan lahayn oo kaliya isticmaalka tamarta hooseeya, laakiin sidoo kale wuxuu wada-shaqeyn karaa soo saarida ethanol buuxda. Daraasadda tijaabada ah waa la dhammeeyey. 200,000 tan/sanad horumarinta xirmo geeddi-socod, iyo 200,000 oo tan/sanad codsi warshadeed ayaa la fulin doonaa dhawaan.

2. Tiknoolajiyada cusubi waxay horseed u tahay horumarka xooggan ee warshado cusub, dib-u-dejin iyo casriyeyn ayaa ilaalinaysa webiga biyo nadiif ah

Maanta, Baling Petrochemical waxa ay noqotay shirkad weyn oo kiimikaad batroolka iyo kiimikooyinka dhuxusha oo la isku daray, iyo sidoo kale kaprolactam-ka ugu weyn ee gudaha iyo ganacsiga wax-soo-saarka caagga ah ee lithium iyo saldhigga wax-soo-saarka epoxy resin ee muhiimka ah. Waxaa ka mid ah, silsiladda wax soo saarka kaprolactam waxaa ka mid ah 500,000 tons/sannad kaprolactam (oo ay ku jiraan ganacsiyada wadajirka ah 200,000 tan), 450,000 tan / sannadkii cyclohexanone, iyo 800,000 tons / ammonium sulfate. Wax soo saarka cagaarka ee Caprolactam oo dhammaystiran oo tignoolajiyada cusub ah waxay gaadheen horumar tignoolajiyadeed oo hore u socod ah oo laga sameeyay warshadaha dhaqameed. Ma aha oo kaliya in ay ka badan deegaanka saaxiibtinimo, qiiqa wasakh ah halkii wax soo saarka waxaa la dhimay 50%, iyo kharashka wax soo saarka unit waa la dhimay 50%, iyo maalgashiga awoodda wax soo saarka ee 10,000 tons waxaa la dhimay in ka yar 150 million yuan. Hoos u dhac ku dhow 80% ayaa soo saartay faa'iidooyin dhaqaale iyo bulsho oo la taaban karo.

Farsamada cusub ee wax soo saarka caprolactam cagaaran ayaa si weyn kor ugu qaaday horumarka degdega ah ee kaprolactam iyo warshadaheeda hoose. Laga bilaabo dhamaadka 2019, Sinopec waxay dhistay tas-hiilaadka wax soo saarka caprolactam badan ee Baling Petrochemical, Zhejiang Baling Hengyi iyo shirkado kale, oo leh miisaan wax soo saar ah oo ah 900,000 tan / sannadkii, xisaabinta 12.16% awoodda wax-soo-saarka caprolactam caalamiga ah iyo awoodda wax-soo-saarka gudaha ee caprolactam 24.39%. Waqtigan xaadirka ah, awoodda wax-soo-saarka cagaarka ah ee waddankaygu wuxuu gaadhay 4 milyan oo tan, isagoo noqday wax-soo-saarka ugu weyn adduunka, oo leh saami suuqeed caalami ah oo ka badan 50%, samaynta 40 bilyan yuan warshado soo baxaya, oo horseedaya horumarka xooggan ee 400 bilyan warshadaha hoose.

Sannadka 2020, guurista silsiladda warshadaha ee kaprolactam ee Baling Petrochemical iyo cusboonaysiinta mashruuca horumarinta iyada oo wadarta maalgashiga 13.95 bilyan yuan ayaa laga bilaabi doonaa Hunan Yueyang Beerta Kiimikada ee Cagaaran. Mashruucu waxa uu qaadanayaa qayb tignoolajiyada cusub ah oo ay si madaxbanaan u soo saartay Sinopec si ay u dhisto silsilad warshadeed 600,000-tan/sanad ah oo kaprolactam ah. Mashruuca waxaa loo dhisi doonaa mashruuc muujinaya iyo mashruuc halbeeg u ah "ilaalinta webiga iyo biyaha nadiifka ah", jebinta "kiimikada ku wareegsan webiga", iyo hirgelinta raritaannada shirkadaha wax soo saarka kiimikada khatarta ah ee magaalooyinka dalka oo dhan. .
