Abstract:
1. A method for humidifying air comprising the steps of: providing a water vapor laden flue gas having a first water vapor partial pressure and a first temperature from a combustion process to a first side of a first permselective liquid water transport membrane; condensing at least a portion of said water vapor on said first side of said first permselective liquid water transport membrane, producing condensed water; transporting said condensed water through said first permselective liquid water transport membrane to a second side of said first permselective liquid water transport membrane opposite said first side; providing a room air stream having a second water vapor partial pressure less than said first water vapor partial pressure and having a second temperature less than said first temperature to said second side of said first permselective liquid water transport membrane; and evaporating said condensed water into said room air stream, producing humidified room air.
