Ekuseni ngomhlaka-27 Disemba 2020, kwamenyezelwa iMiklomelo Yezimboni zaseShayina yesi-6, iMiklomelo Yokuncoma kanye neMiklomelo Yokuqokwa. Isethi ephelele yokukhiqiza okuluhlaza kwe-caprolactam ye-Baling Petrochemical iwine i-China Industrial Award futhi iyona kuphela iyunithi ewine imiklomelo ye-Sinopec. Ngokusekelwa yi-Ministry of Science and Technology kanye ne-Natural Science Foundation yaseShayina, i-Baling Petrochemical and Petrochemical Research Institute iguqule imiphumela yocwaningo lwesayensi etholakale ocwaningweni oluyisisekelo yaba ubuchwepheshe obusha. Ngemva kweminyaka engama-30, izizukulwane ezintathu zinqobe izithiyo eziningi kanye nobunzima, zakha isethi ephelele yobuchwepheshe obuluhlaza obunamalungelo obunikazi azimele, zaphula ngempumelelo ukubusa kwamanye amazwe kubuchwepheshe bokukhiqiza i-caprolactam iminyaka engama-70, futhi zasungula isithombe somkhiqizo wobuchwepheshe bokusungula izinto ezintsha obuzimele baseShayina. Njengamanje, izinga lokuzimela kwe-caprolactam yasekhaya likhuphuke lisuka ku-30% laya ku-94%, futhi ukuthembela kwezwe lami kubuchwepheshe bangaphandle kanye nemikhiqizo engenisiwe kwehle kakhulu.

Iminyaka eyi-1.30 yokusungula izinto ezintsha ngokuzimela, yathuthukisa ngempumelelo isethi ephelele yobuchwepheshe obusha bokukhiqizwa okuluhlaza kwe-caprolactam

I-Caprolactam iyinto ebalulekile yamakhemikhali ephilayo. Njenge-monomer yokukhiqizwa kwemicu yokwenziwa ye-nylon-6 kanye nepulasitiki yobunjiniyela be-nylon-6, isetshenziswa kabanzi ezindwangu, ezimotweni, kuma-elekthronikhi nakwamanye amasimu asebenzisa izinto ezintsha ukuze kusungulwe izinto ezintsha. Imboni ye-caprolactam ihlobene eduze namandla ezomnotho wezwe kanye nezindinganiso zokuphila zabantu, futhi ithatha indawo ebalulekile ekuthuthukisweni nasekuthuthukisweni okuqhubekayo komnotho wezwe.

Ekuqaleni kwawo-1990, iSinopec yachitha cishe ama-yuan ayizigidi eziyizinkulungwane eziyi-10 ukwethula amasethi amathathu ezitshalo zokukhiqiza i-caprolactam ezingamathani angu-50,000 ngonyaka, ezakhiwa eBaling Petrochemical, eNanjing DSM Dongfang Chemical Co., Ltd. kanye naseShijiazhuang Refinery. Ngemva kwalokho, inhlangano yeSinopec yathatha ubuchwepheshe obuyinhloko bokukhiqiza i-caprolactam - ukulungiswa kwe-cyclohexanone oxime njengempumelelo, futhi yenza isethi ephelele yobuchwepheshe obusha bokukhiqiza i-caprolactam eluhlaza eBaling Petrochemical. Ngokusekelwa okunamandla koMnyango Wezesayensi Nobuchwepheshe kanye neNational Natural Science Foundation of China, kanye nesiqondiso se-Academician Min Enze kanye ne-Academician Shu Xingtian be-Chinese Academy of Sciences, ithimba locwaningo libambisene ngobuqotho futhi lasebenza kanzima. Eminyakeni engama-30 edlule, kuye kwakhiwa amalungelo obunikazi angaphezu kwe-100 okusungula izinto zasekhaya nakwamanye amazwe. Kuye kwasungulwa isethi ephelele yobuchwepheshe obusha bokukhiqiza i-caprolactam eluhlaza obuhlanganiswe nezindlela ezintsha zokusabela, izinto ezintsha zokulungisa kanye nobunjiniyela bokusabela obusha.

Lolu buchwepheshe obusha oluphelele lunezobuchwepheshe obuyisithupha obuyinhloko, bonke obufinyelele ezingeni eliphambili lamazwe ngamazwe. Buyi-single-reactor continuous slurry bed cyclohexanone ammoximation process technology ukukhiqiza i-cyclohexanone oxime, i-cyclohexanone oxime Beckman three-stage rearrangement technology, i-Ammonium sulfate neutralization crystallization technology, i-magnetically stabilized bed caprolactam hydrorefining technology, i-cyclohexanone oxime gas phase rearrangement ukukhiqiza ubuchwepheshe be-caprolactam, i-cyclohexene esterification hydrogenation ukukhiqiza ubuchwepheshe obusha be-cyclohexanone. Phakathi kwazo, ubuchwepheshe bokuqala obu-4 busetshenziswe ezimbonini, futhi sekusungulwe amalungelo obunikazi okusungula asekhaya nakwamanye amazwe ayi-137; Kutholwe imiklomelo yesifundazwe neyongqongqoshe eyi-17, okuhlanganisa umklomelo wokuqala wokusungula ubuchwepheshe bukazwelonke kanye nomklomelo wesibili wentuthuko yesayensi nezobuchwepheshe kazwelonke.

Inqubo yokushintshanisa i-“cyclohexanone oxime gas-phase moving bed process without-product ammonium sulfate” ye-Baling Petrochemical nayo yenze intuthuko enkulu ekulungiseleleni i-catalyst, ubuchwepheshe bokusabela, ukuhluzwa komkhiqizo, njll., futhi yaqeda ucwaningo lobuchwepheshe obuncane nobe-pilot. Amathani angu-50,000 ngonyaka wokusetshenziswa kwezimboni. Ngaphezu kwalokho, i-Sinopec yasungula i-“Cyclohexene Esterification Hydrogenation to Cyclohexanone New Process”. Izinga lokusetshenziswa kwe-carbon atom liseduze no-100%, elingagcini nje ngokusetshenziswa kwamandla aphansi, kodwa futhi elingakhiqiza i-ethanol ephelele. Ucwaningo lokuhlola seluqediwe. Ukuthuthukiswa kwephakheji yenqubo yamathani angu-200,000 ngonyaka, kanye nokusetshenziswa kwezimboni kwamathani angu-200,000 ngonyaka kuzokwenziwa maduze.

2. Ubuchwepheshe obusha buqhuba intuthuko enamandla yezimboni ezintsha, ukufuduka kanye nokuthuthukisa kuvikela umfula wamanzi acwebile

Namuhla, i-Baling Petrochemical isibe yinkampani enkulu ehlanganisiwe yamakhemikhali kaphethiloli namalahle, kanye nenkampani enkulu kunazo zonke yasekhaya yokukhiqiza irabha ye-caprolactam ne-lithium kanye nesisekelo esibalulekile sokukhiqiza i-epoxy resin. Phakathi kwazo, uchungechunge lomkhiqizo we-caprolactam luhlanganisa amathani angu-500,000 ngonyaka we-caprolactam (kufaka phakathi ama-joint ventures angu-200,000), amathani angu-450,000 ngonyaka we-cyclohexanone, kanye namathani angu-800,000 ngonyaka we-ammonium sulfate. Amasethi aphelele okukhiqiza okuluhlaza kwe-Caprolactam obuchwepheshe obusha afinyelele intuthuko yezobuchwepheshe eqhubekayo ezimbonini zendabuko. Akukhona nje kuphela ukuthi inobungani nemvelo, ukukhishwa kokungcola ngomkhiqizo ngamunye kuncishisiwe ngo-50%, kanti izindleko zokukhiqiza iyunithi zincishisiwe ngo-50%, kanti ukutshalwa kwezimali emandleni okukhiqiza ngamathani angu-10,000 kuncishisiwe kwaba ngaphansi kwezigidi ezingu-150 zama-yuan. Ukunciphisa cishe ngo-80% kuveze izinzuzo ezinkulu zezomnotho nezenhlalo.

Ubuchwepheshe obusha bokukhiqizwa kwe-green caprolactam bukhuthaze kakhulu intuthuko esheshayo ye-caprolactam kanye nezimboni zayo ezingezansi. Kusukela ekupheleni kuka-2019, i-Sinopec yakhe izindawo eziningi zokukhiqiza i-caprolactam eBaling Petrochemical, eZhejiang Baling Hengyi nakwezinye izinkampani, ngesilinganiso sokukhiqiza samathani angu-900,000 ngonyaka, okubalwa u-12.16% wamandla okukhiqiza i-caprolactam yomhlaba wonke kanye namandla okukhiqiza i-caprolactam yasekhaya angu-24.39%. Njengamanje, amandla okukhiqiza i-green caprolactam yezwe lami afinyelele amathani ayizigidi ezi-4, aba umkhiqizi omkhulu kunabo bonke emhlabeni, onesabelo semakethe yomhlaba wonke esingaphezu kuka-50%, wakha imboni ekhulayo yama-yuan ayizigidigidi ezingama-40, futhi eqhuba intuthuko enamandla yezimboni ezingezansi ezingama-400 billion.

Ngo-2020, iphrojekthi yokuthuthukiswa kokuthutha nokuthuthukiswa kweketanga lezimboni i-Baling Petrochemical enemali elinganiselwa ku-13.95 billion yuan izokwethulwa eHunan Yueyang Green Chemical Industrial Park. Le phrojekthi yamukela ubuchwepheshe obusha obuthuthukiswe ngokuzimela yiSinopec ukwakha iketanga lezimboni i-caprolactam elingamathani angu-600,000 ngonyaka. Le phrojekthi izokwakhiwa njengephrojekthi yokubonisa kanye nephrojekthi yokulinganisa "yokuvikela umfula namanzi acwebile", ukuphula "ukuzungeza kwamakhemikhali komfula", kanye nokuqalisa ukuthuthwa kwamabhizinisi okukhiqiza amakhemikhali ayingozi ezindaweni zasemadolobheni ezinabantu abaningi kulo lonke izwe.
