Cov cuab yeej siv hauv distillation, qee zaum hu ua ib qho tseem, muaj qhov tsawg kawg ntawm lub reboiler lossis lub lauj kaub uas cov khoom siv tau rhuab, lub condenser uas cov cua sov ua kom txias rov qab mus rau lub xeev ua kua, thiab ib lub receiver uas cov concentrated los yog purified kua, hu ua lub distillate, yog sau …
Dab tsi yog cov khoom ua kua ntawm distillation?
Distillation yog txheej txheem ntawm vaporizing cov kua thiab rov qab los ntawm condensing cov vapors. Cov kua uas tsim los ntawm qhov condensation no yog hu ua the distillate.
Dab tsi yog sau ua ntej hauv distillation?
Lub khoom uas muaj qhov kub siab tshaj plaws yog sau rau saum kab. Los ntawm kev txuas ntxiv kom sov cov sib tov kom nce qhov kub thiab txias hauv kem. Cov khoom uas muaj qhov kub siab tshaj plaws yog sau ua ntej.
Dab tsi yog sau rau hauv yooj yim distillation?
Nyob rau hauv ib qho yooj yim distillation, ib homogeneous kua sib tov yog boiled. Qhov nce vapor ces nkag mus rau hauv lub chamber ntawm cov dej txias condenser. Cov vapor condenses rau cov kua, hu ua lub distillate, uas yog ces muab sau rau hauv ib lub nkoj cais.
Dab tsi yog distillate hauv distillation?
Ib lub distillate yog cov vapor hauv ib qho distillation uas tau sau thiab condensed rau hauv cov kua. Xwb, nws yog lub npe ntawm cov khoom tau los ntawm cov txheej txheem distillation.
