A mathematical model was developed to evaluate the influence of structural and operational factors on convective desorption processes (desorption of a liquid from capillary‐porous material). The possibility to utilize this model for the case of water desorption from the polystyrene cation resin CG‐8 is presented. The model accounts for unsteady one‐dimensional simultaneous heat and mass transfer between the gas (humid air) and the solid phase (CG‐8 resin). The identification of effective transport properties for the considered packed bed of material (CG‐8 resin) is discussed. To this purpose, data from the literature are used.
