Kwinkqubo entsonkothileyo yokuhamba kwe-lubricating oil solvent refining, ulawulo loxinaniso luqhuba kuyo yonke inkquboukuthambisa umlinganiselo woxinaniso lweoyile. Umgaqo wokutsalwa usetyenziselwa ukwahlula amacandelo angekhoyo kumacandelo e-oyile yokuthambisa. Le ndlela isebenzisa i-solvents efana ne-furfural kunye ne-phenol ukuphumeza ukutsalwa kwesigaba solwelo phantsi kweemeko ezithile zobushushu, ngokukodwa ukususa i-polycyclic ye-short-side-chain hydrocarbons kunye ne-sulfur / nitrogen-containing compounds.
Isigaba se-solvent esityebileyo esiqulethe amacandelo angafanelekanga kunye nesigaba seoli esisulungekileyo esisulungekileyo sifumana ulwahlulo lokuqala kwikholamu yokukhupha, ephuma kwiindawo ezahlukeneyo ngokulandelanayo. Isigaba esisisityebi se-solvent singena kwinkqubo yokubuyisela i-solvent, apho i-solvent iphinda isetyenziswe ngokusebenzisa i-distillation kunye nezinye iindlela; Isigaba seoli esulungekisiweyo singena kwiinkqubo ezilandelayo ezinjengokuhluba kunye nokomisa ukuze kuqhutyekwe nokususa izinyibilikisi ezishiyekileyo, ukufumana ioyile yesiseko se-oyile esulungekisiweyo esulungekileyo.
Iziphumo zeempazamo zoMlinganiselo woXinano
Intsalela eBalulekileyo yeeNgxelo ezingezizo
Ukuba ulawulo loxinaniso kwi-oyile ecocekileyo iphezulu kakhulu, intsalela yamacandelo angabonakaliyo iya kudlula umgangatho, ukunciphisa kakhulu ukuxhatshazwa kwe-oxidation kunye nokuzinza kwe-thermal yeoli yokuthambisa. Oku kuya kubangela isalathiso se-viscosity engaqhelekanga, ukusilela ukuhlangabezana neemfuno zeemeko zokusebenza, kwaye kunokukhokelela kukonakala kwezixhobo kunye nemiba yokukhuselwa kokusingqongileyo ngenxa yentsalela ye-solvent.
Umngcipheko weNtsalela yokunyibilika
Ukulawula ukuxinana okungachanekanga kunokubangela ukususwa okungaphelelanga kwezinyibilikisi (ezifana ne-furfural) kwioli esulungekisiweyo. Iintsalela zokunyibilikisa ziya krusa amalungu esinyithi. Ngokukodwa kwiindawo ezichanekileyo ezifana ne-oyile yokuthambisa i-aviation, zinokubangela iingozi ezinzulu zokhuseleko ezifana nokuguga kwetywina kunye ne-corrosion perforation.
Ukusilela rhoqo kwiNkqubo yoBuyiselo lwe-Solvent
Uxinaniso olungaqhelekanga kwindawo etyebileyo yokunyibilikisa buya kukhokelela ekuhlambulukeni kwamaqhezu, kwenze buthathaka isakhono sokutsalwa kwesinyibilikisi, kwaye kwenze umjikelo okhohlakeleyo. Ukuqokelela kwamanzi kuya kubangela i-emulsification ye-solvent, efuna unyango olongezelelweyo. Ukungcola okungena kwisistim kuya kuthintela izixhobo, izixhobo zokunxiba, kunye nokwandisa iindleko zokugcinwa kunye nokunciphisa ixesha.
Ingxaki kwiiNzuzo zezoQoqosho kunye nokuThobela
Ulawulo olungachanekanga loxinaniso luya kwandisa iindleko ezifana nokusebenza ngokutsha kwemveliso, inkunkuma enyibilikayo, kunye nokugcinwa kwezixhobo, kwaye kunokukhokelela kwizohlwayo okanye nokunqunyanyiswa kwemveliso kunye nokulungiswa ngenxa yokungathotyelwa kokusingqongileyo.
IKholam yokutsalwa/iNkqubo yoBuyiselo lwe-Solvent
Kwinkqubo yokucoca i-oyile yokuthambisa i-solvent, ikholomu yokukhupha kunye nenkqubo yokubuyisela i-solvent ziyizikhonkco eziphambili. Ukujongwa okuchanekileyo kunye nokulawulwa kweeparamitha zabo zokuxinana kuchaphazela ngokuthe ngqo umgangatho wemveliso, ukusebenza kakuhle kwemveliso, kunye nokhuseleko. Njengesixhobo sexesha langempela lokubeka iliso, imitha yoxinaniso lwe-inline inokufezekisa ukulungelelaniswa okuguquguqukayo kweeparameters zenkqubo ephambili ngokuqhubeka nokuqokelela idatha ye-fluid density kunye nokudibanisa nenkqubo yokulawula. Uxinaniso lweemitha ezingaphakathi kumgca zidla ngokufakelwa kumbhobho ophumayo we-oyile esulungekisiweyo phezulu kwikholamu kunye nombhobho wokuphuma wesinyibilikisi esityebileyo ezantsi koluhlu.
Imisebenzi engundoqo yeemitha zokuxinana okungaphakathi
Ulungelelwaniso oluNgqongileyo lweRatiyo yokunyibilika
Ukuba ubuninzi beoli ecocekileyo phezulu kwikholomu buphezulu kakhulu (kunye namacandelo amaninzi angabonakaliyo), umthamo we-injection ye-solvent uya kwandiswa ngokuzenzekelayo ukuze kuphuculwe ukusebenza kakuhle kwe-extraction; ukuba ukuxinana kuphantsi kakhulu (kunye ne-solvent egqithisileyo), ukusetyenziswa kwe-solvent kuya kuncitshiswa ukuphepha inkunkuma.
Isilumkiso kwangethuba seSigaba soKwahlula okungaqhelekanga
Xa "ukukhukula" okanye "umzila" wenzeke kwikholamu yokukhupha, idatha ye-densitometer iya kutshintsha ngokukhawuleza, kwaye inkqubo inokukhupha i-alamu ngexesha elifanelekileyo kunye nokulungelelanisa iiparitha zokusebenza (ezifana nezinga lokuhamba kunye nokushisa) ukukhusela izingozi zokuvelisa.
UkwaPhulelwaniso loMlayisho weKholam yokutsalwa
Ngokubeka iliso ngokuqhubekayo idatha yoxinaniso, ukuhamba kwezinto kwikholamu kulungelelaniswa ukuphepha ukugqithiswa kwendawo okubangelwa ukuxinana okungalinganiyo kunye nokwandisa umjikelo wokusebenza kwezixhobo.
