Raws li lub hauv paus ntsiab lus ntawm kev sib cais molecular distillation, kev sib cais molecular distillation feem ntau cia siab rau qhov sib txawv ntawm molecular txhais tau dawb txoj kev ntawm lub teeb molecules thiab hnyav molecules. Nyob rau tib lub sijhawm, lub teeb lwg me me kom tau sib cais uas khiav dim thaum txoj kev sib cais yuav ua tau yooj yim los ntawm kev ua kom txias. Kev siv lub teeb ua ntu zus, yog li siv tshuab molecular distillation muaj cov yam ntxwv nram qab no:
(1) Cryogenic distillation deb ntawm cov kub taw tes ntawm cov sib txuas. Kev siv tshuab hluav taws xob (distillation technology) feem ntau tso siab rau qhov sib txawv hauv cov ntsiab lus npau npau nruab nrab ntawm cov sib txuas kom sib cais. Yog li, txhawm rau kom muaj kev sib cais muaj txiaj ntsig, kev sib xyaw yuav tsum sib cais yuav tsum yog lub xeev kub npau npau. Yog li, kev sib cais ntawm cov txheej txheem ntawm cov thev naus laus zis yuav tsum muaj feem cuam tshuam ntau. Siab kub. Lub tshuab molecular distillation sib cais tshuab cia siab rau qhov sib txawv ntawm qhov txhais tau tias tsis pub dawb ntawm cov lus tsa suab molecular ntawm qhov sib txuas. Cov txheej txheem lub tshuab nqus tsev siab tsis tuaj yeem tsuas yog txo tag nrho cov ntsiab lus ntawm cov sib txuas, tab sis kuj tseem nce ntxiv qhov sib txawv ntawm txoj kev ywj pheej sib txawv ntawm cov tebchaw, yog li cov txheej txheem distillation yuav ua tau zoo distillation ntawm qhov kub tsawg.
(2) Distillation hauv qab ultra-low siab. Cov theoretical thev naus laus zis thev naus laus zis kev sib cais txheej txheem tshwm sim nruab nrab ntawm 0.01Pa thiab 0.1Pa. Ultra-low distillation siab tuaj yeem nce ntxiv txoj kev ywj pheej ntawm cov lus qhia molecular ntawm cov sib txuas, yog li nthuav qhov sib txawv ntawm txhais tau tias txoj kev ywj pheej dawb ntawm cov sib txuas, Kom ua tiav txoj kev sib cais. Cov tsoos distillation thev naus laus zis feem ntau yog lauj kaub distillation. Cov lus sib xyaw kom tau muab cais yog thawj zaug vaporized mus rau hauv cov roj ntawm cov pa taws. Cov pa roj cua ua haujlwm tau txuas tawm tag nrho hauv qab qhov kev txiav txim ntawm lub tshuab nqus tsev twj, thiab tuaj yeem tawm tau thaum nws ntws los ntawm lub hws. Qhov kev ncua deb ntawm condenser thiab nto evaporation yog ntev dhau lawm, ua rau ntu no
Qhov kev ncua deb ntawm tag nrho ntawm cov roj cua tsis zoo, yog li nws nyuaj rau kom txo lub siab ntawm cov kua dej evaporation theem. Rau cov tshuab raj molecular distillation, vim tias lub condenser thiab evaporation nto tau npaj zoo heev, ib zaug qhov sib txuas ua ke kom sib cais volatilizes thiab dim, nws yog tam sim ntawd condensed. Yog li, qee qhov siab ntawm cov nplaim hluav taws xob sib txuas ntawm cov hws thiab cov evaporator nto muaj tsawg heev. Kev sib xyaw ua ke ntawm kev ua haujlwm siab.
(3) Kev sib cais sai thiab txuag tau. Nyob rau hauv cov txheej txheem ntawm cov roj molecular distillation, cov sib txuas ua ke kom sib cais ntws tawm los ntawm sab qaum ntawm lub cais lub cev thiab ntws tawm ntawm qhov qis. Nyob rau saum npoo ntawm cov evaporator, qhov sib txuas ua kom sib cais yuav tsim ib cov kua ua kua nrog cov tuab tuab ntawm 2 hli raws li kev ua ntawm zaj duab xis ua ib feem. Cov kua dej ua yeeb yaj kiab-zoo li distillation yog cov txiaj ntsig zoo rau qhov kev khiav tawm ntawm qhov sib tov kom tau sib cais. Nyob rau tib lub sijhawm, hauv cov txheej txheem sib cais molecular distillation, cov nplaim hws thiab cov nplaim dej sab tau muab tso kom ze rau ib leeg, kom lub chaw sib xyaw kom sib cais yuav tau nrawm sai sai thaum nws dim, yog li txo lub sijhawm nyob ntawm qhov kub- rhiab qhov sib xyaw kom tau sib cais ntawm qhov kub thiab txias, uas yog qhov zoo rau kev ua kom lub ntsej muag cov xeeb ceem. Feem ntau, thev naus laus zis thev naus laus zis tsis tuaj yeem tsuas yog txo lub sijhawm lub chaw nyob ntawm cov sib txuas kom sib cais ntawm cov cua kub, tab sis kuj ua kom luv luv ntawm qhov kub-siab gaseous chaw nyob lub sijhawm ntawm kev khiav tawm ntawm cov hluav taws xob thiab cov hws.
