Kwinkqubo enzima yokuhamba kwe-oyile yokuthambisa, ulawulo loxinano luhamba kuyo yonke inkquboumlinganiselo woxinano lweoyile yokuthambisaUmgaqo wokukhupha usetyenziselwa ukwahlula izinto ezingezizo ezifanelekileyo kwiinxalenye zeoyile ezithambisayo. Le ndlela isebenzisa izinyibilikisi ezifana ne-furfural kunye ne-phenol ukufezekisa ukukhupha ulwelo phantsi kweemeko ezithile zobushushu, ngokuyintloko isusa ii-hydrocarbons ze-polycyclic short-side-chain kunye nee-compounds ezine-sulfur/nitrogen.
Isigaba se-solvent esityebileyo esinezinto ezingezizo ezifanelekileyo kunye nesigaba seoli ecocekileyo ecocekileyo zihlulwa okokuqala kwikholamu yokukhupha, ziphuma kwiindawo ezahlukeneyo zokukhupha ngokwahlukeneyo. Isigaba se-solvent esityebileyo singena kwinkqubo yokubuyisela i-solvent, apho i-solvent iphinda isetyenziswe nge-distillation kunye nezinye iindlela; isigaba seoli ecocekileyo singena kwiinkqubo ezilandelayo ezifana nokukrazula nokomisa ukuze kususwe i-solvents eziseleyo, kufumaneke i-oyile esisiseko yeoyile ecocekileyo echanekileyo.
Iziphumo zeempazamo zokulinganisa uxinano
Intsalela Egqithisileyo Yezinto Ezingezizo Ezifanelekileyo
Ukuba ulawulo loxinano kwindawo yokuphuma yeoyile ecociweyo luphezulu kakhulu, intsalela yezinto ezingezizo ezifanelekileyo iya kudlula umgangatho, nto leyo eya kunciphisa kakhulu ukumelana ne-oxidation kunye nokuzinza kobushushu beoyile yokuthambisa. Oku kuya kubangela i-viscosity index engaqhelekanga, ukungaphumeleli ukuhlangabezana neemfuno zeemeko zokusebenza, kwaye kunokukhokelela nakwimiba yokubola kwezixhobo kunye nokukhuselwa kwendalo ngenxa yentsalela ye-solvent.
Umngcipheko weNtsalela yeSolvent
Ulawulo olungachanekanga loxinano lunokubangela ukususwa okungaphelelanga kwezinyibilikisi (ezifana ne-furfural) kwioyile ecociweyo. Iintsalela zesinyibilikisi ziya konakalisa izinto zesinyithi. Ingakumbi kwiindawo ezichanekileyo ezifana neoyile yokuthambisa ngenqwelomoya, zinokubangela iingozi ezinkulu zokhuseleko ezifana nokuguga kwetywina kunye nokugqobhoka komhlwa.
Ukusilela Okuqhelekileyo Kwinkqubo Yokubuyisela Isisombululo
Uxinano olungaqhelekanga kwindawo etyebileyo yokuphuma kwesinyibilikisi kuya kukhokelela ekunciphiseni ubunyulu beenxalenye, buthathaka amandla okukhupha isinyibilikisi, kwaye kwenze umjikelo onzima. Ukuqokelelana kwamanzi kuya kubangela ukuhlanganiswa kwesinyibilikisi, okufuna unyango olongezelelweyo. Ukungcola okungena kwinkqubo kuya kuthintela izixhobo, kugugule izinto, kwaye konyuse iindleko zokugcinwa kunye nexesha lokungasebenzi.
Ingxaki kwiZibonelelo zezoQoqosho kunye nokuThotyelwa kweMithetho
Ulawulo olungachanekanga loxinano luya kunyusa iindleko ezifana nokulungiswa kwemveliso, inkunkuma yesinyibilikisi, kunye nokugcinwa kwezixhobo, kwaye kunokukhokelela kwizohlwayo okanye nokumiswa kwemveliso kunye nokulungiswa ngenxa yokungathobeli imimiselo yendalo.
Inkqubo yokubuyisela ikholamu yokutsala/iSolvent
Kwinkqubo yokucocwa kwe-oyile yokuthambisa, ikholamu yokukhupha kunye nenkqubo yokubuyisela i-solvent ziikhonkco eziphambili. Ukubeka esweni ngokuchanekileyo kunye nolawulo lweeparamitha zazo zoxinano zichaphazela ngokuthe ngqo umgangatho wemveliso, ukusebenza kakuhle kwemveliso, kunye nokhuseleko. Njengesixhobo sokujonga ngexesha langempela, imitha yoxinano oluphakathi inokufezekisa ukwenziwa ngcono okuguquguqukayo kweeparamitha zenkqubo ephambili ngokuqokelela rhoqo idatha yoxinano lolwelo kunye nokudibanisa nenkqubo yolawulo. Iimitha zoxinano oluphakathi zihlala zifakwa kumbhobho wokuphuma weoyile ecociweyo phezulu kwikholamu kunye nombhobho wokuphuma we-solvent etyebileyo ezantsi kwikholamu.
Imisebenzi ephambili yeemitha zoxinano oluphakathi
Uhlengahlengiso oluDynamic lweSolvent Ratio
Ukuba uxinano lweoyile ecociweyo phezulu kwikholamu luphezulu kakhulu (kunye nezinye izinto eziseleyo ezingezizo ezifanelekileyo), umthamo we-solvent injection uya kwandiswa ngokuzenzekelayo ukuphucula ukusebenza kakuhle kokukhupha; ukuba uxinano luphantsi kakhulu (kunye ne-solvent eninzi), ukusetyenziswa kwe-solvent kuya kuncitshiswa ukuze kuthintelwe inkunkuma.
Isilumkiso Kwangethuba Sokwahlulwa Kwesigaba Izinto Ezingaqhelekanga
Xa "ukukhukuliswa" okanye "ukuhanjiswa kwe-channeling" kwenzeka kwikholamu yokukhupha, idatha ye-densitometer iya kutshintshatshintsha ngamandla, kwaye inkqubo inokukhupha ii-alamu ngexesha elifanelekileyo kwaye ilungise iiparameter zokusebenza (ezifana nesantya sokuhamba kunye nobushushu) ukuthintela iingozi zemveliso.
Ukulungiswa koMthwalo weKholamu yokuKhupha
Ngokuhlala ujonga idatha yoxinano, ukuhamba kwezinto kwikholamu kulungelelaniswe ukuze kuthintelwe ukuxinana kwendawo okubangelwa kuxinano olungalinganiyo kwaye kwandise umjikelo wokusebenza kwezixhobo.
