Ngentsasa yomhla wama-27 kuDisemba, ngo-2020, kwabhengezwa iMbasa yesi-6 yoShishino lwaseTshayina, iiMbasa zokuNcoma kunye neeMbasa zokuTyusa. Imveliso entsha ye-caprolactam eluhlaza ye-Caprolactam entsha ye-caprolactam eluhlaza iphumelele iMbasa yoShishino lwase-China kwaye kuphela kweyunithi ephumelele ibhaso ye-Sinopec. Ngenkxaso yoMphathiswa wezeNzululwazi kunye neTeknoloji kunye neSiseko seSayensi yeNdalo yaseChina, i-Baling Petrochemical and Petrochemical Research Institute iye yaguqula iziphumo zophando lwezenzululwazi ezifunyenwe kuphando olusisiseko kwiiteknoloji ezintsha. Emva kweminyaka engama-30, izizukulwana ezithathu zoyise imiqobo kunye neembandezelo ezininzi, zaphuhlisa iseti epheleleyo yetekhnoloji eluhlaza enamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda, zaphule ngempumelelo ubuxhakaxhaka bamazwe angaphandle kwitekhnoloji yemveliso ye-caprolactam iminyaka engama-70, kwaye yaseka umfanekiso wophawu lwetekhnoloji entsha yaseTshayina ezimeleyo. Okwangoku, izinga lokuzimela kwe-caprolactam yasekhaya linyuke ukusuka kuma-30% ukuya kuma-94%, kwaye ukuxhomekeka kwelizwe lam kubuchwepheshe bamazwe angaphandle kunye neemveliso ezivela kumazwe angaphandle kwehle kakhulu.

Iminyaka eyi-1.30 ye-innovation ezimeleyo, iphuhlise ngempumelelo isethi epheleleyo yetekhnoloji entsha yemveliso eluhlaza ye-caprolactam

I-Caprolactam yimathiriyeli ebalulekileyo yekhemikhali ekrwada. Njengemonoma yokuveliswa kweentsinga zenayiloni-6 kunye neeplastiki zobunjineli benayiloni-6, isetyenziswa ngokubanzi kwiimpahla ezilukiweyo, iimoto, i-elektroniki kunye namanye amasimi asebenzisa izinto ezintsha zokuqalisa izinto ezintsha. Ishishini le-caprolactam linxulumene ngokusondeleyo namandla oqoqosho lwelizwe kunye nemigangatho yokuphila yabantu, kwaye likwindawo ebalulekileyo kuphuhliso kunye nokuphucula okuqhubekayo koqoqosho lwelizwe.

Ekuqaleni koo-1990, iSinopec yachitha phantse i-yuan eyi-10 yeebhiliyoni ukwazisa iiseti ezi-3 zeetoni ezingama-50,000/ngonyaka wezityalo zokuvelisa i-caprolactam, ezakhiwa e-Baling Petrochemical, eNanjing DSM Dongfang Chemical Co., Ltd. naseShijiazhuang Refinery. Emva koko, umbutho weSinopec wathatha iteknoloji engundoqo yemveliso ye-caprolactam-ukulungiswa kwe-cyclohexanone oxime njengempumelelo, kwaye yenza isethi epheleleyo yobuchwepheshe obutsha kwimveliso ye-caprolactam eluhlaza kwi-Baling Petrochemical. Ngenkxaso eyomeleleyo yeSebe lezeNzululwazi kunye neTekhnoloji kunye neSiseko seSizwe seSayensi yeNdalo yaseTshayina, kunye nesikhokelo se-Academician Min Enze kunye ne-Academician Shu Xingtian ye-Chinese Academy of Sciences, iqela lophando liye lasebenzisana ngokunyanisekileyo kwaye lasebenza nzima. Kwiminyaka engama-30 edlulileyo, ngaphezulu kwe-100 yamalungelo awodwa omenzi wechiza asekhaya nawangaphandle asekiwe. Iseti epheleleyo yetekhnoloji entsha yemveliso eluhlaza ye-caprolactam edityaniswe ngeendlela ezintsha zokusabela, izinto ezintsha ze-catalytic kunye nobunjineli obutsha bokusabela buphuhlisiwe.

Le seti ipheleleyo yobuchwepheshe obutsha inetekhnoloji engundoqo ezintandathu, zonke zifikelele kwinqanaba eliphambili lamazwe ngamazwe. Ziyi-single-reactor eqhubekayo ye-slurry bed cyclohexanone ammoximation process process ukuvelisa i-cyclohexanone oxime, i-cyclohexanone oxime i-Beckman ye-rearrangement itekhnoloji yenqanaba lesithathu, itekhnoloji ye-Ammonium sulfate neutralization crystallization, i-magnetic stabilized bed caprolactam hydroreximenotechnology m iteknoloji , i-cyclohexene esterification hydrogenation ukuvelisa iteknoloji entsha ye-cyclohexanone. Phakathi kwazo, ubuchwephesha obu-4 bokuqala busetyenziswe kwimizi-mveliso, kwaye iipatent eziyi-137 zasekhaya nezangaphandle zenziwe; Iimbasa ezili-17 zephondo nabaphathiswa ziye zaphunyelelwa, kubandakanywa ibhaso lokuqala eli-1 lokuyila iteknoloji yesizwe kunye nebhaso lesibini lenkqubela yesizwe yenzululwazi nethekhinoloji.

I-“cyclohexanone oxime gas-phase-arrangement” ye-cyclohexanone gas-phase rearrangement inkqubo yebhedi eshukumayo ngaphandle kwemveliso ye-ammonium sulfate” iye yenza inkqubela phambili kulungiselelo lwecatalyst, itekhnoloji yokusabela, ukucokiswa kwemveliso, njl. njl., kwaye yagqiba uphando lobuchwephesha obuncinane kunye nolingo lokulinga. Iitoni ezingama-50,000/ngonyaka kwisicelo semizi-mveliso. Ukongeza, iSinopec ibe nguvulindlela "iCyclohexene Esterification Hydrogenation ukuya kwiCyclohexanone Inkqubo entsha". Izinga lokusetyenziswa kwe-athomu ye-carbon isondele kwi-100%, engenakho ukusetyenziswa kwamandla aphantsi, kodwa inokuvelisa i-ethanol epheleleyo. Uphononongo olulingwayo lugqityiwe. Iitoni ezingama-200,000/ngonyaka wophuhliso lwephakheji yenkqubo, kunye ne-200,000 yeetoni/ngonyaka isicelo soshishino siza kwenziwa kungekudala.

2.Itekhnoloji entsha iqhuba uphuhliso olunamandla lwamashishini amatsha, ukufuduswa kunye nokuphucula ukukhusela umlambo wamanzi acwengileyo.

Namhlanje, i-Baling Petrochemical iye yaba yi-petrochemical enkulu kunye neekhemikhali zamalahle ezidibeneyo, kunye neyona ndawo inkulu yasekhaya ye-caprolactam kunye neshishini lokuvelisa irabha ye-lithium kunye nesiseko esibalulekileyo sokuvelisa i-epoxy resin. Phakathi kwabo, ikhonkco lemveliso ye-caprolactam ibandakanya iitoni ezingama-500,000 / ngonyaka we-caprolactam (kubandakanywa amashishini adibeneyo angama-200,000), iitoni ezingama-450,000 / ngonyaka we-cyclohexanone, kunye ne-800,000 yeetoni / ngonyaka i-ammonium sulfate. Imveliso eluhlaza yeCaprolactam iiseti ezipheleleyo zetekhnoloji entsha iphumelele inkqubela phambili yetekhnoloji kumashishini emveli. Ayigcini nje ngokukhusela indalo, ukukhutshwa kongcoliseko kwimveliso nganye kuncitshiswa ngama-50%, kwaye ixabiso lemveliso yeyunithi lincitshiswe ngama-50%, kwaye utyalo-mali kumthamo wemveliso ngeetoni ezili-10,000 zehliswe ukuya ngaphantsi kwe-150 yezigidi zeeyuan. Ukuncitshiswa okuphantse kube ngama-80% kuvelise inzuzo ebalulekileyo kwezoqoqosho nezentlalo.

I-teknoloji entsha yemveliso ye-caprolactam eluhlaza ikhuthaze kakhulu ukuphuhliswa ngokukhawuleza kwe-caprolactam kunye namashishini ayo asezantsi. Ukuya ekupheleni kuka-2019, iSinopec iye yakha iindawo ezininzi zokuvelisa i-caprolactam kwi-Baling Petrochemical, iZhejiang Baling Hengyi kunye nezinye iinkampani, kunye nomlinganiselo wemveliso we-900,000 yeetoni / ngonyaka, i-accounting ye-12.16% yemveliso ye-caprolactam yehlabathi kunye nomthamo wemveliso ye-caprolactam yasekhaya. 24.39%. Okwangoku, umthamo wemveliso yecaprolactam eluhlaza yelizwe lam ufikelele kwi-4 yezigidi zeetoni, waba ngoyena mvelisi mkhulu wehlabathi, kunye nesabelo semarike yehlabathi engaphezulu kwe-50%, esenza i-40 yebhiliyoni ye-yuan ekhulayo kushishino, kwaye uqhube uphuhliso olomeleleyo lwe-400 yeebhiliyoni zemizi-mveliso esezantsi.

Ngo-2020, i-Baling Petrochemical's caprolactam ye-caprolactam ye-industrial chain chain kunye neprojekthi yophuhliso yophuhliso kunye notyalo-mali olupheleleyo lwe-yuan ye-13.95 yebhiliyoni iya kusungulwa e-Hunan Yueyang Green Chemical Industrial Park. Iprojekthi ithatha ibhetshi yetekhnoloji entsha ephuhliswe ngokuzimeleyo yiSinopec ukwakha i-600,000-ton/year caprolactam industry chain. Le projekthi iza kwakhiwa njengeprojekthi yokubonisa kunye neprojekthi yokulinganisa "yokugada umlambo kunye namanzi acocekileyo", ukwaphula "ikhemikhali ejikeleze umlambo", kunye nokuphumeza ukufuduswa kwamashishini ayingozi okuvelisa imichiza kwiindawo ezixineneyo zedolophu kwilizwe lonke. .
