An experimental study of 3A molecular sieve behavior, in order to obtain anhydrous ethanol, was developed. The adsorption of water in vapor phase was performed in an essentially isothermal fixed bed. 99·9 wt% ethanol was recovered operating with azeotropic distillation and different flow rates. A simple model in terms of a driving force and linear equilibrium was tested. Runs in liquid phase were also carried out, obtaining lower treatment capacities than when working in vapor phase.
