The extraction column characteristics and uses

Extraction tower is a kind of liquid - liquid mass transfer equipment widely used in petroleum refining, chemical industry and environmental protection departments . It has the characteristics of simple structure, easy installation and manufacturing. In the liquid - liquid mass transfer system, severe smaller difference between the two phases, interfacial tension difference is not large, resulting in promoting the interphase mass transfer of the inertia force is small, the ability to separate two phases are separated and the layered not high. In order to improve the efficiency of liquid phase mass transfer equipment, external energy such as stirring, pulse, vibration, etc. is often supplied.
