1.Technology Summary

In October 2011, Shanghai Bi Ke Clean Energy Technology Co., LTD and Dalian Institute of Chemical Physics, Chinese Academy of Sciences jointly developed membrane contactor products. To meet the requirements of natural gas market, The material of Teflon (PTFE, also known as Teflon, the king of the plastic) is produced to the PTFE hollow fiber membrane contactor which is efficient, stable and economic .With the further development of the technology and products, the PTFE membrane contactor can also be used in biogas purification, solvent regeneration, seawater desalination, high salt wastewater recycling, strong acid alkali reclaim and waste water treatment and other industry areas.


2.Introduction of membrane contactor technology 

The principle of membrane contactor on the mass transfer

Substances in the gas phase diffuse in the gas phase boundary layer;

The substances transfer in the hole of membrane;

Substances dissolved and absorbed in the interface of gas and liquid phase;

Substances in liquid interface diffuse to liquid phase;
