Isixazululo Semishini Yokuhlanza I-NMP Esebenzayo: Uhlelo Lokubuyisela Olwenziwe Ngokwezifiso nguPengjin

Isingeniso

I-NMP (i-N-Methyl-2-pyrrolidone) iyisithako esibalulekile ekukhiqizweni kwamabhethri e-lithium. Kodwa-ke, izimboni eziningi zamabhethri eziphakathi nendawo ezinkulu zihlushwa yizinga eliphansi lokubuyisa i-NMP, izindleko eziphezulu zokusebenza, inkomba yokukhishwa okungazinzile kanye nokwehluleka kwemishini njalo. Isixazululo esithembekile sokuhluza i-NMP singasiza amabhizinisi ukunciphisa izindleko, ukuhlangabezana nezidingo zemvelo kanye nokuzinzisa ukukhiqizwa. Leli phepha lethula uhlelo lokuhluza i-NMP olusebenzayo noluphindaphindwayo, oluqinisekiswe yidatha yangempela yephrojekthi.

Iyini Imishini Yokucwilisa i-NMP

Imishini yokuhluza i-NMP iyithuluzi elikhethekile lokubuyisa nokuhlanza imfucuza ye-NMP solvent. Isebenzisa ubuchwepheshe bokulungisa nokuhlukanisa ukususa umswakama nokungcola kuketshezi olungcolile, ukuze i-NMP isetshenziswe kabusha ekukhiqizeni. Isetshenziswa kabanzi ebhethri le-lithium, amandla amasha kanye nemboni yamakhemikhali kagesi. Inani layo eliyinhloko ukunciphisa izindleko zokuthenga i-solvent, ukwehlisa ingcindezi yokukhishwa kwemvelo kanye nokuthuthukisa ukuhlanzeka nokuqina kokukhiqiza.

Izixazululo Ezivamile Zokwelapha ze-NMP

Njengamanje, kunezinhlelo ezintathu eziyinhloko zokwelapha i-NMP embonini. Imishini yokuhluza yendabuko inotshalomali oluphansi, kodwa izinga layo lokululama liphansi, ukusetshenziswa kwamandla kuphezulu futhi ikhwalithi yokungcola ayizinzile. Ukucubungula i-outsourcing kulula, kodwa izindleko zesikhathi eside ziphezulu, ingozi yezokuthutha kunzima ukuyilawula, futhi kulula ukuthinta ukuqhubeka kokukhiqiza. Uhlelo lokuhluza lwe-NMP oluhlanganisiwe lunezinga eliphezulu lokululama, izindleko zokusebenza eziphansi kanye nokwenza izinto ngokuzenzakalela okuphezulu, okuye kwaba ukukhetha okuthandwayo kwamabhizinisi aholayo. Imishini yokuhluza ye-Pengjin NMP iyisistimu ehlanganisiwe esebenza kahle kakhulu eyenzelwe izimo zokusebenza zebhethri le-lithium.

Ukuqhathaniswa kwezixazululo ezahlukene zokwelashwa kwe-NMP

Imishini yokuhluza i-Pengjin NMP inezinzuzo ezisobala ekusebenzeni kahle kokubuyisa, umnotho wokusebenza kanye nokuzivumelanisa nezimo kokukhiqiza okukhulu, okungaletha izinzuzo zezomnotho ezizinzile zesikhathi eside emabhizinisini.

Isixazululo Sokucwilisa se-NMP Esenziwe Ngokwezifiso se-Pengjin

I-Pengjin inikeza izixazululo zokuhluza ze-NMP ezenziwe ngokwezifiso ngokuya ngokukhishwa kwebhizinisi, ukuhlushwa koketshezi olungcolile, izimo zendawo kanye nezindinganiso zokukhishwa komoya. Isinyathelo 1 yenza uphenyo endaweni kanye nokuhlolwa koketshezi olungcolile ukuqinisekisa izidingo zebhizinisi kanye nezimo zokusebenza. Isinyathelo 2 yenza ukulingisa komklamo kanye nenqubo ngokwezifiso ukuze kunqunywe amapharamitha emishini kanye nokwakheka kwayo. Isinyathelo 3 siqedele ukukhiqizwa kwemishini, ukufakwa kanye nokuqaliswa kwayo ukuqinisekisa ukusebenza kohlelo okuzinzile. Isinyathelo 4 sinikeza ukuqeqeshwa komqhubi kanye nesiqondiso sesikhathi eside ngemuva kokuthengisa. Uhlelo luhlanganiswe kakhulu, kulula ukulusebenzisa futhi lungagcina izinga eliphezulu lokutakula ngaphansi komthwalo ogcwele wesikhathi eside.

Imiphumela Yecala Lephrojekthi Yangempela kanye Nedatha

Umkhiqizi webhethri le-lithium eliphakathi nendawo eNingizimu yeShayina ucubungula amathani ayi-15 e-NMP waste liquid ngosuku. Yayivame ukulahlekelwa yi-solvent ephezulu, izindleko zokwelashwa eziphezulu kanye nokukhishwa okungazinzile. Ngemva kokusebenzisa imishini yokuhluza i-NMP eyenziwe ngokwezifiso yiPengjin, izinga lokubuyisa i-NMP landa lisuka ku-78% laya ku-97%, izindleko zansuku zonke ze-solvent zehla cishe ngo-42%, ukukhishwa kwemfucuza kwehle ngaphezu kuka-60%, imishini ingasebenza ngokuqhubekayo amahora angama-24, kanti izinga lokwehluleka lingaphansi kuka-1%. Ibhizinisi labuyisa yonke imali etshaliwe yemishini zingakapheli izinyanga eziyi-10.

Isiphetho

Kumabhizinisi ebhethri le-lithium kanye namabhizinisi amasha amandla, isisombululo sokucwilisa i-NMP esizinzile nesisebenzayo siyisihluthulelo sokunciphisa izindleko kanye nokuthuthukiswa kokusebenza kahle kanye nokuhambisana nokuvikelwa kwemvelo. Imishini yokucwilisa i-Pengjin NMP iqinisekiswe ngamaphrojekthi asebenzayo, ngesilinganiso sokubuyisa esiphezulu, ukusetshenziswa kwamandla okuphansi, ukuzenzakalela okuphezulu kanye nokusebenza okuthembekile. Inganikeza ukwesekwa kokubuyisela nokuhlanzwa kwe-NMP okuzinzile isikhathi eside kwamabhizinisi. I-Pengjin izimisele ukuhlinzeka ngensizakalo yokuklama eyenziwe ngokwezifiso kanye nomjikelezo wokuphila konke kumakhasimende adinga usizo.
