Ekuseni kwangomhla zingama-27 kuZibandlela wezi-2020, kwamenyezelwa Imiklomelo Yezimboni Yesi-6, Imiklomelo Yokuncoma kanye Nemiklomelo Yokuqokwa. Ukukhiqizwa okusha kwe-caprolactam eluhlaza okuhlaza kwe-Baling Petrochemical isethi ephelele yephrojekthi entsha yobuchwepheshe iwine i-China Industrial Award futhi iwukuphela kweyunithi ye-Sinopec ewine imiklomelo. Ngokusekelwa uMnyango Wezesayensi Nobuchwepheshe kanye ne-Natural Science Foundation yase-China, i-Baling Petrochemical and Petrochemical Research Institute iguqule imiphumela yocwaningo lwesayensi etholwe ocwaningweni oluyisisekelo kubuchwepheshe obusha. Ngemva kweminyaka engu-30, izizukulwane ezintathu ziye zanqoba izithiyo nezinsizi ezingenakubalwa, zakha isethi ephelele yobuchwepheshe obuluhlaza obunamalungelo azimele empahla yengqondo, zaphula ngempumelelo ukubusa kwamanye amazwe ngobuchwepheshe bokukhiqiza i-caprolactam iminyaka engu-70, futhi zasungula isithombe somkhiqizo wobuchwepheshe obuzimele bokusungula eChina. Njengamanje, izinga lokukwazi ukuzimela kwe-caprolactam yasekhaya likhuphuke lisuka ku-30% laya kuma-94%, futhi ukuncika kwezwe lami kubuchwepheshe bamazwe angaphandle kanye nemikhiqizo evela kwamanye amazwe kwehle kakhulu.

Iminyaka engu-1.30 yokuqamba okusha okuzimele, ithuthukise ngempumelelo isethi ephelele yobuchwepheshe obusha bokukhiqiza okuluhlaza kwe-caprolactam

I-Caprolactam iyimpahla ebalulekile yamakhemikhali ephilayo. Njenge-monomer yokukhiqiza imicu yokwenziwa yenayiloni-6 kanye namapulasitiki obunjiniyela enayiloni-6, isetshenziswa kakhulu ezindwangu, ezimotweni, ezobuchwepheshe kanye neminye imikhakha esebenzisa izinto ezintsha zokuqamba izinto ezintsha. Imboni ye-caprolactam ihlobene kakhulu namandla omnotho wezwe kanye namazinga okuphila abantu, futhi ithatha isikhundla esibalulekile ekuthuthukisweni nasekuthuthukisweni okuqhubekayo komnotho wezwe.

Ekuqaleni kwawo-1990, iSinopec yachitha cishe ama-yuan ayizigidi eziyizinkulungwane ezingu-10 ukwethula amasethi angu-3 amathani angu-50,000/ngonyaka wezitshalo zokukhiqiza i-caprolactam, ezakhiwa e-Baling Petrochemical, e-Nanjing DSM Dongfang Chemical Co., Ltd. naseShijiazhuang Refinery. Kamuva, inhlangano yeSinopec yathatha ubuchwepheshe obuyisisekelo bokukhiqizwa kwe-caprolactam-ukulungiswa kwe-cyclohexanone oxime njengempumelelo, futhi yenza isethi ephelele yobuchwepheshe obusha bokukhiqizwa kwe-caprolactam eluhlaza e-Baling Petrochemical. Ngokusekelwa okuqinile koMnyango Wezesayensi Nobuchwepheshe kanye ne-National Natural Science Foundation yaseChina, kanye nokuqondiswa kwe-Academician Min Enze kanye ne-Academician Shu Xingtian ye-Chinese Academy of Sciences, ithimba labacwaningi liye labambisana ngobuqotho futhi lasebenza kanzima. Eminyakeni engu-30 edlule, angaphezu kwe-100 amalungelo obunikazi okusungulwa asekhaya nawangaphandle asenziwe. Isethi ephelele yobuchwepheshe obusha bokukhiqiza okuluhlaza kwe-caprolactam okuhlanganiswe izindlela ezintsha zokusabela, izinto ezintsha ze-catalytic kanye nobunjiniyela bokusabela obusha senziwe.

Leli sethi eliphelele lobuchwepheshe obusha linobuchwepheshe obuyisithupha obuyisisekelo, bonke obufinyelele ezingeni elihamba phambili lamazwe ngamazwe. Ziyi-single-reactor eqhubekayo yombhede we-slurry cyclohexanone ammoximation process technology ukukhiqiza i-cyclohexanone oxime, i-cyclohexanone oxime Beckman yezinyathelo ezintathu zokuhlela kabusha ubuchwepheshe, i-Ammonium sulfate neutralization crystallization technology, i-magnetic stabilized bed caprolactam hydrorexirange technology ukukhiqiza ubuchwepheshe be-caprolactam hydrorexirange m ubuchwepheshe , i-cyclohexene esterification hydrogenation ukukhiqiza ubuchwepheshe obusha be-cyclohexanone. Phakathi kwazo, ubuchwepheshe obu-4 bokuqala busetshenziswe ezimbonini, futhi kwakhiwe amalungelo obunikazi okusungulwa kwekhaya nangaphandle angama-137; Imiklomelo eyi-17 yezifundazwe neyongqongqoshe isizuziwe, okuhlanganisa nomklomelo owodwa wokuqala wokusungulwa kwezobuchwepheshe kuzwelonke kanye nomklomelo wesibili owodwa wenqubekelaphambili kazwelonke yesayensi nezobuchwepheshe.

Inqubo ye-Baling Petrochemical “cyclohexanone oxime gas-phase rearrangement move yombhede ngaphandle komkhiqizo we-ammonium sulfate” nayo yenze inqubekelaphambili enkulu ekulungiseleleni izinto ezisizayo, ezobuchwepheshe bokusabela, ukucwengisiswa kwemikhiqizo, njll., futhi yaqeda ucwaningo lobuchwepheshe olusezingeni elincane nolokuhlola. 50,000 amathani/ngonyaka isicelo sezimboni. Ngaphezu kwalokho, iSinopec yaphayona “i-Cyclohexene Esterification Hydrogenation to Cyclohexanone New Process”. Izinga lokusebenzisa i-carbon athomu lisondele ku-100%, elingagcini nje ngokusetshenziswa kwamandla aphansi, kodwa futhi lingakwazi ukukhiqiza ngokubambisana i-ethanol ephelele. Ucwaningo lokulinga seluqediwe. 200,000 amathani/ukuthuthukiswa kwephakheji yenqubo yonyaka, kanye namathani angu-200,000/ngonyaka izicelo zezimboni zizokwenziwa maduze.

2. Ubuchwepheshe obusha bugqugquzela ukuthuthukiswa okunamandla kwezimboni ezintsha, ukufuduka kanye nokuthuthukiswa kuvikela umfula wamanzi acwebile.

Namuhla, i-Baling Petrochemical isiphenduke ibhizinisi elikhulu le-petrochemical kanye namakhemikhali amalahle ahlangene, kanye nebhizinisi elikhulu kunazo zonke lasekhaya le-caprolactam kanye ne-lithium rubber kanye nesisekelo esibalulekile sokukhiqiza i-epoxy resin. Phakathi kwazo, uchungechunge lomkhiqizo we-caprolactam luhlanganisa amathani angu-500,000/ngonyaka we-caprolactam (okuhlanganisa amabhizinisi ahlanganyelwe amathani angu-200,000), amathani angu-450,000/ngonyaka we-cyclohexanone, kanye namathani angu-800,000/ngonyaka i-ammonium sulfate. Ukukhiqizwa okuluhlaza kwe-Caprolactam amasethi aphelele obuchwepheshe obusha azuze inqubekelaphambili yezobuchwepheshe eziya phambili ezimbonini zendabuko. Akukhona nje kuphela ukuthi ayihambisani nemvelo, ukukhishwa okungcolile komkhiqizo weyunithi ngayinye kwehliswa ngo-50%, futhi izindleko zokukhiqiza iyunithi zehliswa ngo-50%, kanye nokutshalwa kwezimali kumthamo wokukhiqiza ngamathani ayi-10,000 kuncipha kuze kube ngaphansi kwama-yuan ayizigidi eziyi-150. Ukwehliswa okucishe kube ngama-80% kukhiqize izinzuzo ezibalulekile zezomnotho nezenhlalo.

Ubuchwepheshe obusha bokukhiqizwa kwe-caprolactam eluhlaza buye bakhuthaza kakhulu ukuthuthukiswa okusheshayo kwe-caprolactam kanye nezimboni zayo ezingezansi. Ekupheleni kuka-2019, iSinopec yakhe izikhungo eziningi zokukhiqiza i-caprolactam e-Baling Petrochemical, e-Zhejiang Baling Hengyi nezinye izinkampani, ngesilinganiso sokukhiqiza esingamathani angu-900,000 ngonyaka, esibalelwa ku-12.16% womthamo wokukhiqiza we-caprolactam emhlabeni jikelele kanye namandla okukhiqiza i-caprolactam yasekhaya. 24.39%. Njengamanje, umthamo wokukhiqiza we-caprolactam oluhlaza wezwe lami usufinyelele amathani ayizigidi ezi-4, usebe ngumkhiqizi omkhulu kunawo wonke emhlabeni, onesabelo semakethe yomhlaba wonke esingaphezu kuka-50%, sakhe imboni esafufusa yamayuan ayizigidi eziyizinkulungwane ezingama-40, futhi iqhubekisela phambili ukuthuthukiswa okunamandla kwezimboni eziyizigidi eziyizinkulungwane ezingama-400 ezansi nomfula.

Ngo-2020, kuzokwethulwa e-Hunan Yueyang Green Chemical Industrial Park ye-Baling Petrochemical's i-caprolactam industrial relocation kanye nokuthuthukisa iphrojekthi yokutshalwa kwezimali okungama-yuan ayizigidi eziyizinkulungwane eziyi-13.95. Le phrojekthi isebenzisa iqoqo lobuchwepheshe obusha obuthuthukiswe ngokuzimela yi-Sinopec ukuze kwakhiwe uchungechunge lwezimboni ze-caprolactam ezingama-600,000/ngonyaka. Le phrojekthi izokwakhiwa njengephrojekthi yokubonisa kanye nephrojekthi yokulinganisa "yokuqapha umfula namanzi acwebile", ukuphula "indawo ezungezile yamakhemikhali yomfula", kanye nokuqalisa ukuthutha amabhizinisi akhiqiza amakhemikhali ayingozi ezindaweni zasemadolobheni ezinabantu abaningi ezweni lonke. .
