In this study, hollow fiber membrane contactors have been applied for gas dehumidification using triethylene glycol as absorbent. The effects of gas and liquid flow rates, inlet concentration of tri-ethylene glycol and flow direction on dehumidification efficiency have been investigated. The results reveal that membrane contactors can remove water vapor very effectively using tri-ethylene glycol, and very low water dew point as low as -50 ℃ can be achieved. It also shows that liquid phase is not the limiting resistance in this system, as a result of very high solubility of water in tri-ethylene glycol.
