New extraction technology The summary of membrane extraction

by:Deyuan      2020-08-08
Also known as fixed interface membrane extraction, membrane extraction which is a membrane process and liquid-liquid extraction process with the combination of new separation technology. Unlike usually liquid-liquid extraction process, membrane extraction of mass transfer process is the separated liquid material and solvent on the surface of the microporous membrane. For example, due to the hydrophobic microporous membrane itself, the hydrophilic solvent impregnated with hydrophobic microporous membrane, infiltration to the side of the microporous membrane. In this way, the extracting agent and the material liquid mass transfer in membrane surface contact. In the process without the traditional extraction process. 。 。

also known as fixed interface membrane extraction, membrane extraction, it is a membrane process and liquid-liquid extraction process with the combination of new separation technology. Unlike usually liquid-liquid extraction process, membrane extraction of mass transfer process is the separated liquid material and solvent on the surface of the microporous membrane. For example, due to the hydrophobic microporous membrane itself, the hydrophilic solvent impregnated with hydrophobic microporous membrane, infiltration to the side of the microporous membrane. In this way, the extracting agent and the material liquid mass transfer in membrane surface contact. The process does not have a traditional droplet dispersion and aggregation phenomenon in the process of extraction.
its advantages are as follows:

because there is no droplet dispersion and aggregation, extraction solvent entrainment phenomenon can be reduced.
membrane extraction process, the two phase respectively on both sides of the membrane, there is no direct contact, can relax the physical requirements of extracting agent, such as density, viscosity, interfacial tension and so on.
there is no return mixed liquid membrane extraction phenomenon, improve the production capacity.
membrane extraction process can realize extraction at the back extraction process, measures such as mobile carrier can be used to promote migration, in order to improve the process of mass transfer efficiency.
material liquid and solvent phase exist on both sides of membrane can be avoided with similar within the supported liquid membrane in the operation of membrane solvent loss problem.








DE - source extraction to recommend new extraction technology Membrane extraction of introduction to help you understand extraction equipment and production capacity, technological process, characteristics of the equipment, such as detailed specification, at the same time can also see the relevant customer case and extraction equipment solution, the research trend, you can also browse all extraction equipment.
