Distillation Sib cais
Distillation yog ib qho kev sib cais ntawm cov khoom siv sib txawv uas siv qhov sib txawv ntawm cov ntsiab lus kub ntawm cov khoom ntawm qhov kub sib txawv kom ua tiav kev sib cais. Los ntawm cua sov qhov sib tov nyob rau hauv ib lub apparatus, ib yam khoom yog thawj vaporized, thiab ces condensed nyob rau hauv ib tug condenser kom tau ib tug ntshiab tshuaj.
Kev cais tawm
Extraction cais yog lwm txoj kev sib cais uas feem ntau siv. Nws ua tiav kev sib cais los ntawm kev hloov qee yam ntawm cov khoom sib tov mus rau lwm qhov hnyav los ntawm kev sib cais lossis cov tshuaj tiv thaiv tshuaj. Txoj kev no feem ntau siv rau kev sib cais cov kua sib tov, thiab cov khoom sib txawv tuaj yeem raug xaiv ua cov extractants.
Kev sib cais crystallization
Kev sib cais crystallization siv qhov sib txawv ntawm solubility ntawm cov tshuaj hauv cov tshuaj kom ua tiav kev sib cais. Qhov sib tov yog muab tso rau ntawm qhov ntsuas kub uas tsim nyog, ua rau ib lossis ntau cov tshuaj crystallize, uas ua rau muaj cov khoom ntshiab.
Sib cais Membrane Technology
Separation membrane technology yog ib txoj kev sib cais cov khoom siv tshwj xeeb sol-gel panels. Los ntawm kev sib cais daim nyias nyias, cov kuab tshuaj thiab cov kuab tshuaj nyob rau hauv thawj qhov sib tov tuaj yeem sib cais. Cov nyhuv sib cais tuaj yeem txhim kho los ntawm kev kho cov kuab tshuaj muaj pes tsawg leeg.
