Résumé

The paper deals with an experimental and theoretical investigation of air humidification/dehumidification processes carried out in a hollow-fibre membrane contactor. The cross-flow contactor consists of a 1.2 m2 total membrane surface of hollow polypropylene capillaries arranged in a staggered array and has a mass transfer area per unit volume of 593 m2/m3. The heat and vapour mass transfer between the liquid phase (water and lithium chloride saturated solution) and the process air is analyzed. Experiments show a high mass transfer efficiency for both humidification and dehumidification. Furthermore, a numerical model to predict heat and mass transfer through the contactor has been developed. Experimental results are in good agreement with theoretical predictions.
