Theoretical and experimental contributions to the study of the behavior of beds of granular desiccants in removing moisture from a flowing gas stream are presented. A differential equation for the performance of such a bed is developed under various limiting assumptions regarding the mechanism of the process. Rigorous and approximate solutions to the equation, together with a method of testing experimental data for conformity to it, are developed. Critical analysis of previous contributions to this theory is undertaken.
A set of equations, mathematically derived from the Normal and Binomial Laws of Frequency Distributions, are presented expressing liquid distribution with and without wall effects.
