Résumé

Rotating packed bed (RPB) has owned the significant advantages for gas-liquid heat and mass transfer process intensification. This work considered the feasibility of applying a countercurrent-flow rotating packed bed (RPB) for air dehumidification. Lithium chloride solution was used as the model absorbent. The dehumidification efficiency in countercurrent-flow RPB was influenced by rotational speed. Heat and mass transfer between air and liquid desiccant in a countercurrent-flow RPB is investigated. Analytical solutions of air and desiccant parameters are given in the present study, based on the analogy between the combined heat and mass transfer process in the countercurrent-flow RPB. The analytical solutions can be used in the optimization of the countercurrent-flow RPB dehumidifier.
