Abstract

Dehumidified air is required in many industrial applications. In recent years attempts have been made to use liquid desiccants for dehumidifying air. Dehumidifying with a liquid desiccant usually scrubs the air stream, not only providing conditioning but also cleaning and disinfecting the air. Different liquid desiccants are available in the market, lithium chloride and calcium chloride are the most commonly used desiccants in industry. In this paper performance of these two desiccants in dehumidifying the air is reported in detail. The heat and mass transfer coefficients have been evaluated for calcium chloride-air and lithium chloride-air contact systems using ceramic Raschig rings as the packing material. The derived transfer coefficients are used to analyze the performance of the dehumidifier. The results clearly indicate that lithium chloride-air contact system performance is better than the performance of the calcium chloride-air contact system. The heat and mass transfer analysis is extended to study the effect of various parameters such as liquid inlet temperature, liquid inlet flow rate, air inlet temperature, etc. on the performance of the dehumidifier.
