The performance of a liquid desiccant regenerator, equipped with structured packing made of wood, was investigated for the regeneration of triethylene glycol (TEG). The effects of air and desiccant flow rates, air and desiccant temperature, and desiccant concentration were studied to assess their impact on the regeneration process. The influence of these parameters on the performance of the desiccant regenerator was evaluated in terms of the rate of water evaporation and the effectiveness of the regeneration process. It was found that under the conditions of this study, the desiccant inlet temperature was the most favorable variable, while the inlet desiccant concentration was the least favorable with respect to the regeneration process. The air mass flux increased the rate of water evaporation, but reduced the regenerator effectiveness significantly. The other parameters had a negligible effect. The results of this study were in agreement with the Chung and Luo correlation and published literature.
