Subaxnimadii Diseembar 27, 2020, ayaa lagu dhawaaqay Abaalmarinta 6aad ee Warshadaha Shiinaha, Abaalmarinta Ammaanta iyo Abaalmarinta Magacaabista. Mashruuca cusub ee wax soo saarka cagaaran ee caprolactam ee Baling Petrochemical oo dhammaystiran ayaa ku guuleystay Abaalmarinta Warshadaha Shiinaha waana cutubka kaliya ee abaalmarinta ku guuleystay ee Sinopec. Iyada oo taageero ka heleysa Wasaaradda Sayniska iyo Teknolojiyadda iyo Hay'adda Sayniska Dabiiciga ah ee Shiinaha, Machadka Cilmi-baarista Batroolka iyo Batroolka ee Baling wuxuu natiijooyinka cilmi-baarista sayniska ee laga helay cilmi-baarista aasaasiga ah u beddelay teknoolojiyad cusub. 30 sano ka dib, saddex jiil ayaa ka gudbay caqabado iyo dhibaatooyin aan la tirin karin, waxay sameeyeen qalab dhammaystiran oo teknoolojiyad cagaaran ah oo leh xuquuq hanti-garaadeed oo madax-bannaan, waxay si guul leh u jebiyeen kaligii-talisnimada shisheeye ee tignoolajiyada wax soo saarka caprolactam muddo 70 sano ah, waxayna aasaaseen muuqaalka summada ee tignoolajiyada hal-abuurka madaxbannaan ee Shiinaha. Waqtigan xaadirka ah, heerka isku-filnaanshaha caprolactam ee gudaha ayaa ka kacay 30% ilaa 94%, ku tiirsanaanta dalkaygu ee tignoolajiyada shisheeye iyo alaabada la soo dejiyo ayaa si weyn hoos ugu dhacday.

1.30 sano oo hal-abuur madax-bannaan, si guul leh ayaa loo sameeyay teknoolojiyad cusub oo dhammaystiran oo loogu talagalay wax soo saarka cagaaran ee caprolactam

Caprolactam waa walax kiimiko dabiici ah oo muhiim ah. Sida monomer loogu talagalay soo saarista fiilooyinka synthetic-ka ee naylon-6 iyo balaastikada injineernimada naylon-6, waxaa si weyn loogu isticmaalaa dharka, baabuurta, elektaroonigga iyo meelaha kale ee isticmaala agab cusub oo loogu talagalay hal-abuurka. Warshadaha caprolactam waxay si dhow ula xiriiraan xoogga dhaqaale ee dalka iyo heerarka nolosha dadka, waxayna ku jiraan boos muhiim ah horumarinta iyo horumarinta joogtada ah ee dhaqaalaha qaranka.

Horraantii 1990-meeyadii, Sinopec waxay ku bixisay ku dhawaad ​​10 bilyan oo yuan si ay u soo bandhigto 3 qaybood oo ah 50,000 oo tan/sanadkii wax soo saarka caprolactam, kuwaas oo laga dhisay Baling Petrochemical, Nanjing DSM Dongfang Chemical Co., Ltd. iyo Shijiazhuang Refinery. Intaa ka dib, ururka Sinopec wuxuu qaatay tignoolajiyada asaasiga ah ee wax soo saarka caprolactam - diyaarinta oxime cyclohexanone sida horumar, waxayna fulisay tignoolajiyad cusub oo dhammaystiran oo loogu talagalay wax soo saarka caprolactam cagaaran ee Baling Petrochemical. Iyada oo taageero xooggan laga helayo Wasaaradda Sayniska iyo Teknolojiyadda iyo Hay'adda Qaranka ee Sayniska Dabiiciga ah ee Shiinaha, iyo hagidda Aqoonyahan Min Enze iyo Aqoonyahan Shu Xingtian oo ka tirsan Akadeemiyada Sayniska Shiinaha, kooxda cilmi-baarista ayaa si daacad ah u wada shaqeeyay oo si adag u shaqeeyay. 30-kii sano ee la soo dhaafay, in ka badan 100 shati oo hal-abuur gudaha iyo dibadda ah ayaa la sameeyay. Tiknoolajiyad dhammaystiran oo cusub oo loogu talagalay wax soo saarka cagaaran ee caprolactam oo lagu daray waddooyin cusub oo falgal ah, agab cusub oo kaalshiyam ah iyo injineerinka falgalka cusub ayaa la sameeyay.

Tiknoolajiyadan cusub ee dhammaystiran waxay leedahay lix tiknoolajiyadood oo asaasi ah, kuwaas oo dhammaantood gaaray heerka ugu sarreeya ee caalamiga ah. Waa tiknoolajiyada habka isku-dhafka ah ee hal-reaktor-ka ah ee slurry bed cyclohexanone ammoximation si loo soo saaro oxime cyclohexanone, tiknoolajiyada dib-u-habaynta saddex-marxalad ah ee cyclohexanone oxime Beckman, tiknoolajiyada ka-hortagga kala-goynta Ammonium sulfate, tiknoolajiyada hydrorefining ee sariirta ee birlabta ah ee la dejiyay, dib-u-habaynta wejiga gaaska ee cyclohexanone oxime si loo soo saaro tiknoolajiyada caprolactam, hydrogenation-ka cyclohexene esterification si loo soo saaro tiknoolajiyada cusub ee cyclohexanone. Kuwaas waxaa ka mid ah, 4-ta tiknoolaji ee ugu horreeya waxaa lagu dabaqay warshado ahaan, waxaana la sameeyay 137 shati oo hal-abuur gudaha iyo dibadda ah; 17 abaalmarin oo heer gobol iyo heer wasiir ah ayaa la guuleystay, oo ay ku jiraan 1 abaalmarin oo koowaad oo ah hal-abuurka tiknoolajiyada qaranka iyo 1 abaalmarin labaad oo loogu talagalay horumarka sayniska iyo tiknoolajiyada qaranka.

Baling Petrochemical's "habka dib-u-habaynta gaaska ee cyclohexanone oxime oo aan lahayn ammonium sulfate" ayaa sidoo kale horumar horumar leh ka samaysay diyaarinta kicinta, tignoolajiyada falcelinta, sifaynta alaabta, iwm., waxayna dhammaystirtay cilmi-baaris tignoolajiyadeed oo yar yar iyo mid tijaabo ah. 50,000 tan/sanadkii codsiga warshadaha. Intaa waxaa dheer, Sinopec waxay hormuud ka ahayd "Hydrogenation-ka Cyclohexene Esterification Hydrogenation ilaa Cyclohexanone New Process". Heerka isticmaalka atamka kaarboonku waa ku dhawaad ​​100%, kaas oo aan kaliya lahayn isticmaalka tamarta oo hooseeya, laakiin sidoo kale wuxuu si wadajir ah u soo saari karaa ethanol dhammaystiran. Daraasadda tijaabada ah ayaa la dhammeeyay. Horumarinta xirmooyinka habka 200,000 tan/sanadkii, iyo 200,000 tan/sanadkii codsiga warshadaha ayaa dhawaan la fulin doonaa.

2. Tiknoolajiyadda cusub waxay horseedaa horumarka xooggan ee warshadaha cusub, dib u dejinta iyo casriyeynta waxay ilaaliyaan webi biyo saafi ah leh

Maanta, Baling Petrochemical waxay noqotay shirkad ballaaran oo isku-dhafan oo kiimikooyin batrool iyo dhuxul ah, iyo sidoo kale shirkad weyn oo wax soo saar caprolactam iyo caag lithium ah iyo saldhig muhiim ah oo wax soo saarka epoxy resin ah. Kuwaas waxaa ka mid ah silsiladda wax soo saarka caprolactam 500,000 tan/sanadkii caprolactam (oo ay ku jiraan shirkadaha wadajirka ah 200,000 tan), 450,000 tan/sanadkii cyclohexanone, iyo 800,000 tan/sanadkii ammonium sulfate. Wax soo saarka cagaaran ee Caprolactam oo dhammaystiran oo tignoolajiyada cusub ah ayaa gaaray horumar tignoolajiyadeed oo horumarsan oo ka socda warshadaha dhaqameed. Ma aha oo kaliya inay deegaanka u fiican tahay, qiiqa wasakhowga halkii unug ayaa la dhimay 50%, kharashka wax soo saarka halbeeggana waxaa la dhimay 50%, maalgashiga awoodda wax soo saarka 10,000 tan kastana waxaa la dhimay wax ka yar 150 milyan oo yuan. Hoos u dhac ku dhawaad ​​80% ayaa soo saaray faa'iidooyin dhaqaale iyo bulsho oo muhiim ah.

Tiknoolajiyadda cusub ee wax soo saarka caprolactam ee cagaaran ayaa si weyn u dhiirrigelisay horumarka degdegga ah ee caprolactam iyo warshadaheeda hoose. Ilaa dhammaadka 2019, Sinopec waxay dhistay xarumo badan oo wax soo saar caprolactam ah oo ku yaal Baling Petrochemical, Zhejiang Baling Hengyi iyo shirkado kale, iyadoo leh baaxad wax soo saar oo ah 900,000 tan/sanadkii, taasoo ka dhigan 12.16% awoodda wax soo saarka caprolactam ee adduunka iyo awoodda wax soo saarka caprolactam ee gudaha 24.39%. Waqtigan xaadirka ah, awoodda wax soo saarka caprolactam ee cagaaran ee dalkayga ayaa gaartay 4 milyan oo tan, taasoo noqotay soo-saaraha ugu weyn adduunka, iyadoo leh saami suuq caalami ah oo ka badan 50%, taasoo samaysa warshado soo koraya oo gaaraya 40 bilyan oo yuan, waxayna horseedday horumarka xooggan ee warshadaha hoose ee 400 bilyan.

Sannadka 2020, mashruuca horumarinta silsiladda warshadaha ee caprolactam ee Baling Petrochemical ayaa laga bilaabi doonaa Hunan Yueyang Green Chemical Industrial Park. Mashruucu wuxuu qaadanayaa dufcad tiknoolajiyad cusub ah oo si madax-bannaan u soo saartay Sinopec si loo dhiso silsilad warshadeed oo caprolactam ah oo 600,000-tan/sanadkii ah. Mashruuca waxaa loo dhisi doonaa sidii mashruuc muujinaya iyo mashruuc halbeeg ah oo loogu talagalay "ilaalinta webiga iyo biyaha nadiifka ah", jebinta "xeerarka kiimikada ee webiga", iyo hirgelinta rarista shirkadaha wax soo saarka kiimikada ee khatarta ah ee ku yaal magaalooyinka dadku ku badan yihiin ee dalka oo dhan.
