IUhlelo lokubuyisa i-solvent ye-NMPIqukethe izingxenye eziningana ezibalulekile, ngayinye inendima ethile enkambisweni yokutakula. Lezi zingxenye zisebenza ndawonye ukususa ngempumelelo i-NMP solvent emifudlaneni yenqubo, ukuyiphinda isetshenziswe ukuze isetshenziswe kabusha, nokuqinisekisa ukuhambisana nemithethonqubo yezemvelo. Nansi incazelo eningiliziwe yezingxenye kanye nezindima zazo:
Ithangi Lokuphakelayo noma Umkhumbi Wokubamba:
Ithangi lokuphakelayo noma isitsha sokubamba yilapho isinyibilikisi se-NMP esingcolisiwe siqoqwa khona ekuqaleni kusuka emifudlaneni ehlukahlukene yenqubo. Lesi sakhi sisebenza njengesitsha sokugcina sesikhashana sesinyibilikisi ngaphambi kokuba sidlule enkambisweni yokutakula.
Ikholomu Yokuhluza:
Ikholomu yokuhluza iyisici esiyinhloko sohlelo lokubuyisa i-solvent lapho kwenzeka khona ukuhlukaniswa kwe-solvent ye-NMP ezintweni ezingcolisayo. Ikholomu isebenzisa isimiso sokuhluza okuyi-fractional, lapho ingxube ishiswa khona ukuze i-solvent ishiswe, bese umhwamuko uhlanganiswa ube uketshezi, uhlukaniswe nezinye izingxenye ngokusekelwe ekuhlukeni kwamaphuzu abilayo.
I-Reboiler:
I-reboiler iyi-heat exchanger etholakala phansi kwekholomu yokuhluza. Umsebenzi wayo oyinhloko ukunikeza ukushisa phansi kwekholomu, ukufutha ukudla okuketshezi futhi kube lula ukuhlukaniswa kwe-NMP solvent ezintweni ezingcolisayo.
I-Condenser:
I-condenser ingenye i-heat exchanger etholakala phezulu kwekholomu yokuhluza. Indima yayo ukupholisa nokubuyisela umhwamuko we-NMP esimweni soketshezi ngemva kokuba usuhlukaniswe nokungcola. I-solvent ye-NMP ehlanganisiwe iyaqoqwa futhi igcinwe ukuze isetshenziswe kabusha.
Isihlukanisi Se-solvent Yokubuyisa:
Isihlukanisi se-solvent sokubuyisa siyingxenye esiza ukuhlukanisa noma yimiphi iminonjana eseleyo yokungcola ku-solvent ye-NMP etholiwe. Siqinisekisa ukuthi i-solvent ephinde yasetshenziswa ihlangabezana nezimfuneko zobumsulwa ngaphambi kokuba ibuyiselwe enkambisweni.
Izishintshi Zokushisa:
Ama-heat exchanger asetshenziswa kulo lonke uhlelo lokubuyisa i-solvent ukuze adlulise ukushisa kahle phakathi kwemithombo yenqubo ehlukene. Asiza ukuthuthukisa ukusetshenziswa kwamandla ngokubuyisa ukushisa kusuka emifudlaneni yenqubo ephumayo bese ekudlulisela emifudlaneni engenayo, okunciphisa ukusetshenziswa kwamandla okuphelele.
Amaphampu namaValvu:
Amaphampu namavalvu kuyizinto ezibalulekile ezisetshenziswa ukulawula ukugeleza kwe-solvent kanye nezinye izinto eziwuketshezi zenqubo ngaphakathi kohlelo lokutakula. Ziqinisekisa ukugeleza okufanele kwe-solvent ngezigaba ezahlukene zenqubo yokutakula futhi zivumela ukulungiswa kwamazinga okugeleza njengoba kudingeka.
Uhlelo Lokulawula Nokusebenzisa Izinsimbi:
Izinhlelo zezinsimbi kanye nokulawula ziqapha futhi zilawule amapharamitha ahlukahlukene njengokushisa, ingcindezi, amazinga okugeleza, kanye nokugcwala kwe-solvent kuyo yonke inqubo yokutakula. Zihlinzeka ngedatha yesikhathi sangempela futhi zivumela opharetha ukuthi balungise amapharamitha okusebenza ukuze bathuthukise ukusebenza kwesistimu futhi baqinisekise ukuphepha.
Izinhlelo Zokuphepha:
Izinhlelo zokuphepha zifakwe ohlelweni lokubuyisa i-solvent ukuze kuvinjelwe futhi kuncishiswe izingozi ezingaba khona, njengokucindezela ngokweqile, ukushisa ngokweqile, noma ukungasebenzi kahle kwemishini. Lezi zinhlelo zifaka ama-valve okusiza ukucindezela, izinzwa zokushisa, izindlela zokuvala eziphuthumayo, kanye nama-alamu ukuqinisekisa ukusebenza okuphephile.
Ukulawulwa Kwemvelo:
Ukulawulwa kwemvelo kuyasetshenziswa ukuqinisekisa ukuhambisana nezindinganiso zomthetho zokukhishwa kwegesi kanye nokulahlwa kwemfucuza. Lokhu kungafaka phakathi izihlanzi noma izihlungi zokususa noma yikuphi ukungcola okusele okuvela kumagesi okukhipha umoya ngaphambi kokuba kukhishwe emoyeni.
Izinhlelo Zokuqapha Nokubika:
Izinhlelo zokuqapha nokubika zinikeza opharetha idatha yesikhathi sangempela ngokusebenza kwesistimu, okuhlanganisa amazinga okubuyisa i-solvent, amazinga okuhlanzeka, ukusetshenziswa kwamandla, kanye nokuhambisana nemithethonqubo yemvelo. Lolu lwazi lusetshenziselwa ukwenza ngcono ukusebenza kwesistimu nokulandelela ukusebenza ngokuhamba kwesikhathi.
