Hauv cov txheej txheem nyuaj ntawm cov roj nplua nyeem cov kuab tshuaj refining, kev tswj qhov ceev khiav los ntawm tag nrho cov txheej txheem ntawmkev ntsuas qhov ceev ntawm cov roj nplua nyeem. Lub hauv paus ntsiab lus ntawm kev rho tawm yog siv los cais cov khoom tsis zoo ntawm cov roj lubricating. Txoj kev no siv cov kuab tshuaj xws li furfural thiab phenol los ua kom tau cov kua-theem rho tawm hauv qab qhov kub tshwj xeeb, feem ntau tshem tawm cov polycyclic luv-sab-saw hydrocarbons thiab sulfur / nitrogen-muaj cov tshuaj sib xyaw.
Cov theem nplua nuj ntawm cov kuab tshuaj uas muaj cov khoom tsis zoo thiab cov theem roj uas tau ua kom huv si raug sib cais ua ntej hauv kab rho tawm, ntws tawm ntawm ntau qhov chaw sib txawv. Cov theem nplua nuj ntawm cov kuab tshuaj nkag mus rau hauv lub kaw lus rov qab cov kuab tshuaj, qhov twg cov kuab tshuaj raug rov ua dua los ntawm kev sib xyaw thiab lwm txoj hauv kev; cov theem roj uas tau ua kom huv si nkag mus rau hauv cov txheej txheem tom ntej xws li kev rho tawm thiab ziab kom tshem tawm cov kuab tshuaj seem, tau txais cov roj nplua nyeem uas tau ua kom huv si.
Cov txiaj ntsig ntawm qhov yuam kev ntsuas qhov ceev
Cov Khoom seem ntau dhau ntawm cov khoom tsis zoo tagnrho
Yog tias qhov kev tswj ceev ntawm qhov hluav taws xob ntawm cov roj refined siab dhau, cov seem ntawm cov khoom tsis zoo yuav tshaj qhov tus qauv, txo qhov kev tiv thaiv oxidation thiab thermal stability ntawm cov roj lubricating. Qhov no yuav ua rau cov viscosity index tsis zoo, ua tsis tau raws li qhov yuav tsum tau ua ntawm cov xwm txheej ua haujlwm, thiab tej zaum yuav ua rau cov khoom siv xeb thiab teeb meem kev tiv thaiv ib puag ncig vim yog cov kuab tshuaj seem.
Kev Pheej Hmoo ntawm Cov Khoom Siv Solvent
Kev tswj qhov ceev tsis raug yuav ua rau tshem tawm cov kuab tshuaj tsis tiav (xws li furfural) hauv cov roj ua kom huv. Cov kuab tshuaj seem yuav ua rau cov khoom siv hlau xeb. Tshwj xeeb tshaj yog nyob rau hauv cov teb uas muaj kev ntsuas siab xws li roj lubricating aviation, lawv yuav ua rau muaj kev phom sij loj xws li kev laus ntawm lub foob thiab kev xeb.
Kev Ua Tsis Zoo Ntau Zaus Hauv Lub Tshuab Rov Qab Tau Cov Tshuaj Solvent
Qhov ceev tsis zoo ntawm qhov tawm ntawm cov kuab tshuaj nplua nuj yuav ua rau qhov purity ntawm cov feem tsawg dua, ua rau lub peev xwm rho tawm ntawm cov kuab tshuaj tsis muaj zog, thiab tsim ib lub voj voog phem. Cov dej sib sau ua ke yuav ua rau cov kuab tshuaj emulsification, xav tau kev kho ntxiv. Cov khoom tsis huv nkag mus rau hauv lub kaw lus kuj tseem yuav thaiv cov khoom siv, hnav cov khoom, thiab ua rau cov nqi kho thiab lub sijhawm tsis ua haujlwm ntau ntxiv.
Kev Kub Ntxhov hauv Cov Nyiaj Pab Kev Lag Luam thiab Kev Ua Raws Cai
Kev tswj qhov ceev tsis raug yuav ua rau cov nqi nce ntxiv xws li kev ua haujlwm dua tshiab, cov kuab tshuaj pov tseg, thiab kev saib xyuas cov khoom siv, thiab tej zaum yuav ua rau raug nplua lossis txawm tias raug ncua kev tsim khoom thiab kho qhov teeb meem vim tsis ua raws li ib puag ncig.
Kev rho tawm kem / Kev rov qab los ntawm cov kuab tshuaj
Hauv cov txheej txheem ua kom cov roj nplua nyeem, lub kem rho tawm thiab lub kaw lus rov qab cov kuab tshuaj yog cov txuas tseem ceeb. Kev saib xyuas thiab tswj hwm lawv cov ntsuas qhov ceev ncaj qha cuam tshuam rau cov khoom zoo, kev ua haujlwm ntau lawm, thiab kev nyab xeeb. Ua lub cuab yeej saib xyuas lub sijhawm tiag tiag, lub ntsuas qhov ceev hauv kab tuaj yeem ua tiav kev ua kom zoo dua ntawm cov txheej txheem tseem ceeb los ntawm kev sau cov ntaub ntawv ceev ntawm cov kua dej thiab txuas nrog lub kaw lus tswj. Cov ntsuas qhov ceev hauv kab feem ntau raug ntsia rau ntawm cov kav dej tawm ntawm cov roj ua kom zoo nyob rau sab saum toj ntawm kem thiab cov kav dej tawm ntawm cov kuab tshuaj nplua nuj nyob rau hauv qab ntawm kem.
Cov Haujlwm Tseem Ceeb ntawm cov ntsuas qhov ceev hauv kab
Kev Kho Kom Zoo Dua ntawm Qhov Sib Piv ntawm Cov Tshuaj
Yog tias qhov ceev ntawm cov roj ua kom huv si nyob rau sab saum toj ntawm kem siab dhau (nrog ntau cov khoom seem tsis zoo), qhov ntim tshuaj txhaj tshuaj yuav raug nce ntxiv kom txhim kho kev ua haujlwm ntawm kev rho tawm; yog tias qhov ceev qis dhau (nrog cov tshuaj ntau dhau), kev siv cov tshuaj yuav raug txo kom tsis txhob muaj pov tseg.
Kev Ceeb Toom Thaum Ntxov Txog Kev Sib Cais Ntawm Theem
Thaum "dej nyab" lossis "channeling" tshwm sim hauv kem rho tawm, cov ntaub ntawv densitometer yuav hloov pauv sai heev, thiab lub kaw lus tuaj yeem tshaj tawm cov lus ceeb toom raws sijhawm thiab kho cov kev ua haujlwm (xws li tus nqi ntws thiab kub) kom tiv thaiv kev raug mob ntau lawm.
Kev Txhim Kho ntawm Kev Rho Tawm Hauv Kab
Los ntawm kev saib xyuas cov ntaub ntawv ceev nrooj tas li, cov khoom siv ntws hauv kem tau sib npaug kom tsis txhob muaj kev thauj khoom ntau dhau los ntawm qhov ceev tsis sib npaug thiab txuas ntxiv lub voj voog ua haujlwm ntawm cov khoom siv.
Cov txiaj ntsig ntawm Lonnmeter Inline Density Meters
LonnmeterCov ntsuas qhov ntom ntom inlinetau sawv tawm ntawm cov khoom lag luam hauv tib lub lag luam nrog lawv cov kev ua tau zoo thiab kev hloov pauv zoo heev tom qab ntau xyoo ntawm kev txheeb xyuas kev ua lag luam, muab cov kev daws teeb meem txhim khu kev qha rau kev saib xyuas cov kua dej hauv ntau yam lag luam. Cov neeg siv khoom tuaj yeem xaiv cov ntsuas qhov ceev inline nrog cov kev ntsuas sib txawv raws li cov xwm txheej ua haujlwm tshwj xeeb.
