IInkqubo yokubuyisela i-solvent ye-NMPIqulethe izinto ezibalulekileyo ezininzi, nganye inendima ethile kwinkqubo yokubuyisela kwimeko yesiqhelo. Ezi zinto zisebenza kunye ukususa ngokufanelekileyo i-NMP solvent kwimijelo yenkqubo, ukuyiphinda isetyenziswe ukuze isetyenziswe kwakhona, kunye nokuqinisekisa ukuthotyelwa kwemigaqo yokusingqongileyo. Nantsi inkcazo eneenkcukacha yezi zinto kunye nemisebenzi yazo:
Itanki Yokutya okanye Inqanawa Yokubamba:
Itanki yokutya okanye isitya sokubamba kulapho i-solvent ye-NMP engcolisiweyo iqokelelwa khona ekuqaleni kwimijelo eyahlukeneyo yenkqubo. Eli candelo lisebenza njengesitya sokugcina sexeshana se-solvent ngaphambi kokuba idlule kwinkqubo yokubuyisela.
Ikholamu yokunyibilikisa:
Ikholamu yokunyibilikisa yeyona nto iphambili kwinkqubo yokubuyisa i-solvent apho ukwahlulwa kwe-NMP solvent kwizinto ezingcolisayo kwenzeka khona. Ikholamu isebenzisa umgaqo we-fractional distillation, apho umxube ufudunyezwa ukuze utshise i-solvent, uze emva koko umphunga ujijelwe kwimo yolwelo, ulwahlule kwezinye izinto ngokusekelwe kumahluko kwiindawo ezibilayo.
I-Reboiler:
I-reboiler sisitshintshi sobushushu esikwisiseko sekholamu yokunyibilikisa. Umsebenzi waso oyintloko kukubonelela ngobushushu ezantsi kwekholamu, ukufutha ukutya kolwelo kunye nokwenza kube lula ukwahlula isinyibilikisi se-NMP kwizinto ezingcolisayo.
Isikhondensi:
I-condenser yenye i-heat exchanger ekwindawo ephezulu ye-distillation column. Indima yayo kukupholisa nokubuyisela umphunga we-NMP kwimo engamanzi emva kokuba wahlulwe kwizinto ezingcolileyo. I-NMP solvent edibeneyo iyaqokelelwa kwaye igcinwe ukuze isetyenziswe kwakhona.
Isahluli seSombululo sokuBuyisa:
Isihluzi sokubuyisela esiphinda sisetyenziswe sisixhobo esinceda ukwahlula naziphi na iintsalela zezinto ezingcolisayo kwi-NMP solvent efunyenweyo. Siqinisekisa ukuba i-solvent ephinda isetyenziswe iyahlangabezana nemigangatho yobumsulwa ngaphambi kokuba ifakwe kwakhona kwinkqubo.
Izitshintshi zobushushu:
Izitshintshi zobushushu zisetyenziswa kuyo yonke inkqubo yokubuyisela i-solvent ukuhambisa ubushushu ngokufanelekileyo phakathi kwemithombo eyahlukeneyo yenkqubo. Zinceda ukuphucula ukusetyenziswa kwamandla ngokubuyisela ubushushu kwimithombo yenkqubo ephumayo kunye nokubudlulisela kwimithombo engenayo, kunciphisa ukusetyenziswa kwamandla ngokubanzi.
Iimpompo kunye neeValve:
Iimpompo kunye neevalvu zizinto ezibalulekileyo ezisetyenziselwa ukulawula ukuhamba kwe-solvent kunye nezinye izinto eziphuma kwinkqubo yokubuyisela. Ziqinisekisa ukujikeleza kakuhle kwe-solvent kwizigaba ezahlukeneyo zenkqubo yokubuyisela kwaye zivumela uhlengahlengiso kwizinga lokuhamba njengoko kufuneka.
Inkqubo yoLawulo lwezixhobo kunye nezixhobo:
Iinkqubo zezixhobo kunye nolawulo zijonga kwaye zilawula iiparameter ezahlukeneyo ezifana nobushushu, uxinzelelo, amazinga okuhamba, kunye noxinzelelo lwe-solvent kuyo yonke inkqubo yokubuyisela kwimeko yesiqhelo. Zibonelela ngedatha yexesha langempela kwaye zivumela abaqhubi ukuba bahlengahlengise iiparameter zokusebenza ukuze baphucule ukusebenza kwenkqubo kwaye baqinisekise ukhuseleko.
Iinkqubo zoKhuseleko:
Iinkqubo zokhuseleko zifakwe kwinkqubo yokubuyisela i-solvent ukuthintela nokunciphisa iingozi ezinokubakho, ezinje ngoxinzelelo olugqithisileyo, ubushushu obugqithisileyo, okanye ukungasebenzi kakuhle kwezixhobo. Ezi nkqubo ziquka iivalvu zokunciphisa uxinzelelo, izinzwa zobushushu, iindlela zokuvala ungxamiseko, kunye nee-alamu ukuqinisekisa ukusebenza ngokukhuselekileyo.
Ulawulo lweNdalo:
Ulawulo lokusingqongileyo luyaphunyezwa ukuqinisekisa ukuthotyelwa kwemigangatho yolawulo lokukhutshwa kwenkunkuma kunye nokulahlwa kwenkunkuma. Oku kungabandakanya ii-scrubbers okanye izihluzi zokususa naziphi na izinto ezingcolisayo ezisele kwiigesi zokukhupha umoya ngaphambi kokuba zikhutshwe ziye emoyeni.
Iinkqubo zokubeka iliso kunye neengxelo:
Iinkqubo zokubeka esweni kunye nokunika ingxelo zibonelela abaqhubi ngedatha yexesha langempela malunga nokusebenza kwenkqubo, kubandakanya amazinga okubuyisa isinyibilikisi, amanqanaba okucoceka, ukusetyenziswa kwamandla, kunye nokuthobela imithetho yokusingqongileyo. Olu lwazi lusetyenziselwa ukuphucula ukusebenza kwenkqubo kunye nokulandelela ukusebenza kwayo ngokuhamba kwexesha.
