Current Research Topics

Development of new membrane technology for gas and vapor separation. Membrane dehumidification, membrane separation for carbon dioxide, VOC removal from air and pervaporation separation of ethanol/water are current research topics.

1. Separation and recovery of carbon dioxide from air using amine liquid membrane
   A surface -soaked liquid membrane construction was developed. By using the liquid membrane with amine liquid a CO2 concentrated
   air feed equipment is applying to a green house.
2. Dehumidification and humidification of air using a liquid membrane with hygroscopic liquid
   Hygroscopic liquid, i.e. triethylene glycol, can be applied for water vapor separation in air as a liquid membrane. A continuous separation equipment of membrane humidification or dehumidification of air are developing and theoretically analyzed.
3. Membrane distillation for pure water making
   Membrane distillation has been expected to apply making pure water from sea or surface water. There are many research topics to the development of membrane distillation process. In our laboratory, membrane surface treatment, operation optimization for energy saving and equipment constriction are studying.
