Résumé

In the paper, an attempt has been made to develop an absorber for small-size absorption systems. A mathematical model and a computer code for evaluating the theoretical performance of such absorber were developed. This model and code take into account the essential parameters such as solution inlet and outlet conditions, cooling water inlet conditions and absorber geometry. Variation of solution temperature and concentration, cooling water temperature, absorption rate, and heat duty across the absorber were presented graphically. Compared to the conventional absorber design, this absorber is expected to attain higher heat and mass transfer coefficients and wetting area and hence a better performance and a reduction in absorber size.
