IInkqubo yokubuyisela i-solvent ye-NMPiquka amacandelo amaninzi abalulekileyo, ngalinye lisebenza indima ethile kwinkqubo yokubuyisela. La macandelo asebenza kunye ukuze asuse ngokufanelekileyo isinyibilikisi se-NMP kwimisinga yenkqubo, siphinde sisetyenziswe ukuze sisetyenziswe kwakhona, kwaye siqinisekise ukuthotyelwa kwemimiselo yokusingqongileyo. Nantsi ingcaciso enzulu yamacandelo kunye neendima zawo:
ITanki yokutyisa okanye iSikhephe sokubamba:
Itanki yesondlo okanye isitya sokubamba kulapho isinyibilikisi se-NMP esingcolisekileyo siqokelelwa ekuqaleni kwimijelo eyahlukeneyo yenkqubo. Eli candelo lisebenza njengesikhongozeli sogcino sexeshana sesinyibilikisi phambi kokuba singene kwinkqubo yokubuyisela.
Umhlathi Wokuhluza:
Ikholamu ye-distillation yinxalenye ephambili yenkqubo yokubuyisela i-solvent apho ukuhlukana kwe-solvent ye-NMP kwizinto ezingcolileyo kwenzeka. Ikholamu isebenzisa umgaqo we-fractional distillation, apho umxube ufudunyezwa ukukhupha i-solvent, kwaye umphunga uphinda ujikwe ubuyele kwimo yolwelo, uyahlula kwezinye iinqununu ngokusekelwe kumahluko kumanqaku abilayo.
IReboiler:
I-reboiler ngumtshintshi wokushisa obekwe kwisiseko sekholomu ye-distillation. Umsebenzi wayo ophambili kukubonelela ngobushushu ukuya ezantsi kwekholamu, ukufunxa i-liquid feed kunye nokuququzelela ukuhlukana kwe-solvent ye-NMP kwizinto ezingcolileyo.
Icondenser:
I-condenser yenye i-heat exchanger ebekwe phezulu kwikholamu ye-distillation. Indima yayo kukupholisa kunye nokujiya umphunga we-NMP ubuyele kwimo elulwelo emva kokuba wohluliwe kwizinto ezingcolisayo. Isinyibilikisi se-NMP esiconsisiweyo siyaqokelelwa kwaye sigcinwe ukuze sisetyenziswe kwakhona.
Ubuyiselo lwe-Solvent Umahluli:
Isahluli se-solvent yokubuyisela licandelo elinceda ukwahlula nayiphi na imikhondo eseleyo yezingcoliso kwisinyibilikisi esifunyenweyo se-NMP. Iqinisekisa ukuba i-solvent ehlaziyiweyo idibana neenkcukacha zococeko ngaphambi kokuba iphinde ifakwe kwinkqubo.
IziTshintshisi zoBubushushu:
Ukutshintshana kobushushu kusetyenziswa kuyo yonke inkqubo yokubuyisela i-solvent ukuhambisa ubushushu ngokufanelekileyo phakathi kwemijelo yenkqubo eyahlukeneyo. Banceda ekuphuculeni ukusetyenziswa kwamandla ngokufumana kwakhona ubushushu obuvela kwimisinga yenkqubo ephumayo kwaye bugqithiselwe kwimisinga engenayo, ukunciphisa ukusetyenziswa kwamandla ngokubanzi.
Iimpompo kunye neeValve:
Iipompo kunye neevalvu zizinto ezibalulekileyo ezisetyenziselwa ukulawula ukuhamba kwe-solvent kunye nezinye iinkqubo zolwelo ngaphakathi kwenkqubo yokubuyisela. Baqinisekisa ukujikeleza okufanelekileyo kwe-solvent ngokusebenzisa izigaba ezahlukeneyo zenkqubo yokubuyisela kwaye uvumele uhlengahlengiso kumazinga okuhamba njengoko kufuneka.
Isixhobo kunye neNkqubo yoLawulo:
Iinkqubo zezixhobo kunye nokulawula zilawula kwaye zilawula iiparitha ezahlukeneyo ezifana nobushushu, uxinzelelo, amazinga okuhamba, kunye nokugxilwa kwe-solvent kuyo yonke inkqubo yokubuyisela. Banikezela ngedatha yexesha langempela kwaye benze ukuba abaqhubi bahlengahlengise iiparitha zokusebenza ukuze kuphuculwe ukusebenza kwenkqubo kunye nokuqinisekisa ukhuseleko.
Iinkqubo zoKhuseleko:
Iinkqubo zokhuseleko zibandakanyiwe kwinkqubo yokubuyisela i-solvent ukuze kuthintelwe kunye nokunciphisa iingozi ezinokubakho, ezifana noxinzelelo olugqithisileyo, ukufudumala, okanye ukungasebenzi kakuhle kwezixhobo. Ezi nkqubo ziquka i-valve yokunciphisa uxinzelelo, i-sensor sensors, iindlela zokuvala ngokukhawuleza, kunye ne-alamu ukuqinisekisa ukusebenza ngokukhuselekileyo.
Ulawulo lokusingqongileyo:
Ulawulo lokusingqongileyo luyaphunyezwa ukuqinisekisa ukuthotyelwa kwemigangatho yolawulo lokukhutshwa kwezinto ezikhutshwayo nokulahlwa kwenkunkuma. Oku kunokubandakanya ukukhuhla okanye izihluzi zokususa naziphi na izingcolisi eziseleyo kwiigesi zokukhupha ngaphambi kokuba zikhutshelwe emoyeni.
Iinkqubo zokuJonga nokuNika iNgxelo:
Iinkqubo zokubeka iliso kunye neengxelo zibonelela abaqhubi ngedatha yexesha langempela ekusebenzeni kwenkqubo, kubandakanywa amazinga okubuyisela i-solvent, amanqanaba okucoceka, ukusetyenziswa kwamandla, kunye nokuthotyelwa kwemimiselo yokusingqongileyo. Olu lwazi lusetyenziselwa ukwandisa ukusebenza kwenkqubo kunye nokulandelela ukusebenza ngexesha.
