Ngentsasa kaDisemba 27, 2020, kwabhengezwa amabhaso e-6th Industry Awards, amabhaso okuncoma kunye namabhaso okutyumba. Iprojekthi entsha ye-Baling Petrochemical yemveliso eluhlaza ye-caprolactam ye-Baling Petrochemical iphumelele i-China Industrial Award kwaye yeyona yunithi iphumelele amabhaso ye-Sinopec. Ngenkxaso yoMphathiswa weSayensi neTekhnoloji kunye ne-Natural Science Foundation yaseTshayina, i-Baling Petrochemical kunye ne-Petrochemical Research Institute iguqule iziphumo zophando lwesayensi ezifunyenwe kuphando olusisiseko zaba ziiteknoloji ezintsha. Emva kweminyaka engama-30, izizukulwana ezintathu zoyise iingxaki ezininzi, zaphuhlisa iseti epheleleyo yeeteknoloji eziluhlaza ezinamalungelo obunikazi obuzimeleyo, zaphula ngempumelelo ulawulo lwangaphandle kwiteknoloji yemveliso ye-caprolactam kangangeminyaka engama-70, zaza zaseka umfanekiso wophawu lwetekhnoloji yokuvelisa ezimeleyo yaseTshayina. Okwangoku, izinga lokuzinza kwe-caprolactam yasekhaya linyuke ukusuka kwi-30% ukuya kwi-94%, kwaye ukuxhomekeka kwelizwe lam kubuchwepheshe bangaphandle kunye neemveliso ezingenisiweyo kwehle kakhulu.

Iminyaka eli-1.30 yokuvelisa izinto ezintsha ngokuzimeleyo, iphuhlise ngempumelelo iseti epheleleyo yetekhnoloji entsha yokuvelisa i-caprolactam eluhlaza

I-Caprolactam sisixhobo esibalulekileyo sekhemikhali yendalo. Njenge-monomer yokuvelisa iifayibha zokwenziwa ze-nylon-6 kunye neeplastiki zobunjineli ze-nylon-6, isetyenziswa kakhulu kwimpahla yokulahlwa, kwiimoto, kwii-elektroniki nakwamanye amacandelo asebenzisa izixhobo ezintsha ukwenza izinto ezintsha. Ishishini le-caprolactam linxulumene kakhulu namandla oqoqosho lwelizwe kunye nemigangatho yokuphila yabantu, kwaye lithatha indawo ebalulekileyo kuphuhliso kunye nophuculo oluqhubekayo loqoqosho lwesizwe.

Ekuqaleni kweminyaka yoo-1990, iSinopec yachitha phantse i-10 yeebhiliyoni zeeyuan ukwazisa iiseti ezi-3 zezityalo zemveliso ye-caprolactam ezingama-50,000 ngonyaka, ezakhiwa eBaling Petrochemical, eNanjing DSM Dongfang Chemical Co., Ltd. kunye naseShijiazhuang Refinery. Emva koko, umbutho weSinopec wathabatha itekhnoloji ephambili yokuvelisa i-caprolactam-ukulungiswa kwe-cyclohexanone oxime njengempumelelo, waza wenza iseti epheleleyo yetekhnoloji entsha yokuvelisa i-caprolactam eluhlaza eBaling Petrochemical. Ngenkxaso enamandla yoMphathiswa weSayensi neTekhnoloji kunye neNational Natural Science Foundation yaseTshayina, kunye nesikhokelo se-Academician Min Enze kunye ne-Academician Shu Xingtian ye-Chinese Academy of Sciences, iqela lophando lisebenzisane ngokunyanisekileyo kwaye lisebenze nzima. Kwiminyaka engama-30 edlulileyo, kuye kwasekwa amalungelo obunikazi angaphezu kwe-100 okuvelisa izinto zasekhaya nezangaphandle. Kuye kwaphuhliswa iseti epheleleyo yetekhnoloji entsha yokuvelisa i-caprolactam eluhlaza edityaniswe neendlela ezintsha zokusabela, izinto ezintsha zokulungisa kunye nobunjineli obutsha bokusabela.

Olu seti lupheleleyo lweetekhnoloji ezintsha luneetekhnoloji ezintandathu eziphambili, zonke ezifikelele kwinqanaba eliphambili lamazwe ngamazwe. Ziyiteknoloji yenkqubo yokunyibilikisa i-cyclohexanone eqhubekayo ye-single-reactor ukuvelisa i-cyclohexanone oxime, itekhnoloji yokuhlengahlengisa i-cyclohexanone oxime Beckman enezigaba ezintathu, itekhnoloji yokunyibilikisa i-Ammonium sulfate neutralization, itekhnoloji yokuhlengahlengisa i-caprolactam hydrorefining ezinzileyo ngemagnethi, i-cyclohexanone oxime gas phase rearrangement ukuvelisa itekhnoloji ye-caprolactam, i-cyclohexanone esterification hydrogenation ukuvelisa itekhnoloji entsha ye-cyclohexanone. Phakathi kwazo, iitekhnoloji zokuqala ezi-4 zisetyenziswe kwimizi-mveliso, kwaye kuye kwenziwa amalungelo obunikazi okuvelisa asekhaya nangaphandle ali-137; Kuphunyelelwe amabhaso ali-17 ephondo nabaphathiswa, kuquka ibhaso lokuqala lokuvelisa itekhnoloji yesizwe kunye nebhaso lesibini lenkqubela phambili yesayensi netekhnoloji yesizwe.

Inkqubo yokulungisa ibhedi yokuhambisa i-“cyclohexanone oxime gas-phase rearrangement moving bed ngaphandle kwemveliso ye-ammonium sulfate” ye-Baling Petrochemical ikwaqhubele phambili ekulungiseleleni i-catalyst, iteknoloji yokusabela, ukucocwa kwemveliso, njl.njl., kwaye igqibe uphando lwetekhnoloji oluncinci nolusebenzisa i-pilot. Iitoni ezingama-50,000 ngonyaka kwishishini. Ukongeza, i-Sinopec yaba nguvulindlela kwi-“Cyclohexene Esterification Hydrogenation to Cyclohexanone New Process”. Izinga lokusetyenziswa kwe-athomu yekhabhoni lisondele kwi-100%, elingagcini nje ngokusetyenziswa kwamandla aphantsi, kodwa likwanokuvelisa i-ethanol epheleleyo. Uphononongo lovavanyo lugqityiwe. Uphuhliso lwephakheji yenkqubo yeetoni ezingama-200,000 ngonyaka, kunye nokusetyenziswa kwemveliso kweetoni ezingama-200,000 ngonyaka kuya kwenziwa kungekudala.

2. Ubuchwepheshe obutsha buqhuba uphuhliso olunamandla lwamashishini amatsha, ukufuduka kunye nokuphucula kukhusela umlambo wamanzi acocekileyo

Namhlanje, iBaling Petrochemical ibe yinkampani enkulu edibeneyo yeekhemikhali zepetrochemical kunye namalahle, kunye neyona nkampani inkulu yemveliso yerabha ye-caprolactam kunye ne-lithium kunye nesiseko esibalulekileyo semveliso ye-epoxy resin. Phakathi kwazo, uthotho lwemveliso ye-caprolactam luquka iitoni ezingama-500,000 ngonyaka ze-caprolactam (kubandakanya ii-joint ventures ezingama-200,000), iitoni ezingama-450,000 ngonyaka ze-cyclohexanone, kunye neetoni ezingama-800,000 ngonyaka ze-ammonium sulfate. Iiseti ezipheleleyo zemveliso eluhlaza ye-Caprolactam zobuchwepheshe obutsha zifikelele kwinkqubela phambili yetekhnoloji kumashishini emveli. Ayipheleli nje ekubeni inobuhlobo nokusingqongileyo, ukukhutshwa kongcoliseko ngemveliso nganye yeyunithi kuncitshiswa ngama-50%, kwaye iindleko zemveliso nganye zincitshiswa ngama-50%, kwaye utyalo-mali kumandla emveliso nganye yeetoni ezili-10,000 luncitshiswe lube ngaphantsi kwe-150 yezigidi zeeyuan. Ukunciphisa phantse i-80% kuvelise iingenelo ezibalulekileyo kwezoqoqosho nakwezentlalo.

Itekhnoloji entsha yemveliso eluhlaza ye-caprolactam ikhuthaze kakhulu uphuhliso olukhawulezileyo lwe-caprolactam kunye namashishini ayo asezantsi. Ukusukela ekupheleni kuka-2019, iSinopec yakhe izakhiwo ezininzi zemveliso ye-caprolactam eBaling Petrochemical, eZhejiang Baling Hengyi nakwezinye iinkampani, ngesikali semveliso seetoni ezingama-900,000 ngonyaka, ebalelwa kwi-12.16% yamandla emveliso ye-caprolactam yehlabathi kunye namandla emveliso ye-caprolactam yasekhaya ye-24.39%. Okwangoku, amandla emveliso ye-caprolactam eluhlaza yelizwe lam afikelele kwiitoni ezi-4, eba ngumvelisi omkhulu kwihlabathi, onesabelo semarike yehlabathi esingaphezulu kwe-50%, esenza ishishini elikhulayo le-yuan ezingama-40 eebhiliyoni, kwaye liqhuba uphuhliso olunamandla lwamashishini asezantsi angama-400 eebhiliyoni.

Ngowama-2020, iprojekthi yophuhliso lwe-caprolactam yemizi-mveliso yeBaling Petrochemical enotyalo-mali olupheleleyo lwe-13.95 yeebhiliyoni zeerandi iya kuqaliswa eHunan Yueyang Green Chemical Industrial Park. Le projekthi yamkela uluhlu lweetekhnoloji ezintsha eziphuhliswe ngokuzimeleyo yiSinopec ukwakha i-caprolactam yemizi-mveliso ye-600,000-tons/ngonyaka. Le projekthi iya kwakhiwa njengeprojekthi yokubonisa kunye neprojekthi yokulinganisa "ukukhusela umlambo namanzi acocekileyo", ukwaphula "ukujikeleza kweekhemikhali komlambo", kunye nokuphumeza ukufuduswa kwamashishini emveliso yeekhemikhali eziyingozi kwiindawo zasezidolophini ezinabantu abaninzi kulo lonke ilizwe.
