Outline of Final Research Achievements

This project was focused to gas and vapor separation in air using liquid membrane. Materials for the membrane were mainly ionic liquids, which is non-volatile, low-viscosity and high absorption to gas and vapors. In the application for CO2 separation in the air, amine components are mixed to the ionic liquid. The performance as a CO2 concentrated-air feeder was proved for green-house application. The second application was dehumidification of air. Proposed membrane dehumidification equipment show a dehumidification rate of 10 g-water/h. The third application was VOC separation in the air. Through the camber test, the liquid membrane with ionic liquid effectively separate VOC vapors in ppm-order. One important result was that the imidazorium ionic liquid can separate aromatic hydrocarbon from hydrocarbon mixtures.
