IIsistimu yokubuyisela i-solvent ye-NMPiqukethe izingxenye ezibalulekile ezimbalwa, ngayinye idlala indima ethile enqubweni yokutakula. Lezi zingxenye zisebenza ndawonye ukuze zikhiphe isincibilikisi se-NMP ngempumelelo ekusakazweni kwenqubo, ziphinde zisetshenziswe ukuze ziphinde zisetshenziswe, futhi ziqinisekise ukuthobela imithetho yemvelo. Nansi incazelo enemininingwane yezingxenye nezindima zazo:
Ithangi lokuphakelayo noma umkhumbi wokubamba:
Ithangi lokuphakelayo noma umkhumbi wokubamba kulapho isincibilikisi se-NMP esingcolile siqoqwa khona ekuqaleni kwezinqubo ezihlukahlukene zokusakaza. Lesi sici sisebenza njengesiqukathi sesikhashana sokugcina isincibilikisi ngaphambi kokuthi singene ohlelweni lokubuyisela.
Ikholomu Yokuhluza:
Ikholomu ye-distillation iyingxenye emaphakathi yesistimu yokubuyisela i-solvent lapho ukuhlukaniswa kwe-solvent ye-NMP kusuka kukungcola kwenzeka. Ikholomu isebenzisa isimiso sokuhluzwa kwe-fractional distillation, lapho ingxube ishiselwa khona ukuze i-solvent ihwamuke, bese umhwamuko ufingqa ubuyele esimweni esiwuketshezi, uwuhlukanise kwezinye izingxenye ngokusekelwe ekwehlukeni kwamaphoyinti abilayo.
I-Reboiler:
I-reboiler iyisishintshi sokushisa esitholakala phansi kwekholomu yokukhishwa kwe-distillation. Umsebenzi wayo oyinhloko ukunikeza ukushisa phansi kwekholomu, ukuhwashisa okuphakelayo okuwuketshezi nokwenza kube lula ukuhlukaniswa kwe-solvent ye-NMP kokungcolisa.
I-Condenser:
I-condenser ingesinye isishintshi sokushisa esitholakala phezulu kwekholomu yokukhipha isisu. Indima yayo ukupholisa kanye nokuminyanisa umhwamuko we-NMP ubuyele esimweni esiwuketshezi ngemva kokuba usuhlukene nokungcola. I-solvent ye-NMP ejiyile iyaqoqwa futhi igcinwe ukuze isetshenziswe kabusha.
I-Recovery Solvent Separator:
Isihlukanisi se-solvent yokubuyisela siyingxenye esiza ukuhlukanisa noma yiziphi izinsalela ezisele zokungcola kusinyibilikisi se-NMP esitholiwe. Iqinisekisa ukuthi i-solvent egaywe kabusha ihlangabezana nezicaciso zokuhlanzeka ngaphambi kokuba iphinde ifakwe kunqubo.
Izishintshi Zokushisa:
Izishintshisi zokushisa zisetshenziswa kulo lonke uhlelo lokubuyisela i-solvent ukuze kudluliswe ukushisa kahle phakathi kokusakaza kwenqubo ehlukene. Basiza ukuthuthukisa ukusetshenziswa kwamandla ngokubuyisela ukushisa okuvela emfuleni wenqubo ephumayo futhi bakudlulisele emifudlaneni engenayo, behlise ukusetshenziswa kwamandla kukonke.
Amaphampu namavalvu:
Amaphampu nama-valve yizingxenye ezibalulekile ezisetshenziselwa ukulawula ukugeleza kwe-solvent kanye nolunye uketshezi lwenqubo ngaphakathi kwesistimu yokutakula. Baqinisekisa ukujikeleza okufanele kwe-solvent ngezigaba ezahlukene zenqubo yokutakula futhi bavumele ukulungiswa kumazinga okugeleza njengoba kudingeka.
Amathuluzi Nokulawula Uhlelo:
Amasistimu wamathuluzi nokulawula aqapha futhi alawule amapharamitha ahlukahlukene njengezinga lokushisa, ingcindezi, amazinga okugeleza, nokugxila kwe-solvent kuyo yonke inqubo yokutakula. Bahlinzeka ngedatha yesikhathi sangempela futhi banike amandla opharetha ukuthi balungise imingcele yokusebenza ukuze bathuthukise ukusebenza kwesistimu futhi baqinisekise ukuphepha.
Amasistimu okuphepha:
Amasistimu okuphepha afakwe ohlelweni lokutakula izincibilikisi ukuze kuvinjelwe futhi kuncishiswe izingozi ezingaba khona, njengokucindezela ngokweqile, ukushisa ngokweqile, noma ukungasebenzi kahle kwemishini. Lezi zinhlelo zihlanganisa ama-valve okusiza ukucindezela, izinzwa zokushisa, izindlela zokuvala izimo eziphuthumayo, nama-alamu ukuqinisekisa ukusebenza okuphephile.
Izilawuli Zemvelo:
Ukulawulwa kwemvelo kuyasetshenziswa ukuze kuqinisekiswe ukuthotshelwa kwezindinganiso zokulawula ukungcola nokulahlwa kwemfucuza. Lokhu kungase kuhlanganise izihlungi noma izihlungi ukuze kususwe noma yikuphi ukungcola okusele kumagesi okukhipha umoya ngaphambi kokuba akhishelwe emkhathini.
Amasistimu Wokuqapha Nokubika:
Amasistimu okuqapha nawokubika ahlinzeka opharetha ngedatha yesikhathi sangempela ekusebenzeni kwesistimu, okuhlanganisa izilinganiso zokutholwa kwe-solvent, amazinga okuhlanzeka, ukusetshenziswa kwamandla, nokuthobela imithetho yemvelo. Lolu lwazi lusetshenziselwa ukuthuthukisa ukusebenza kwesistimu nokulandelela ukusebenza ngokuhamba kwesikhathi.
