Abstract

The present investigation was to increase ethanol concentration in ethanol-water vapor from a solar ethanol distillation by a 3A molecular sieve packed bed installed between evaporative and condensing sections of a 10 liter brewery tank. The brewery tank was designed similar to that of a local Thai Wisdom unit. The heating source came from a 2 m2 flat plate solar collector. The study was carried out with a 10 liter batch of solution with various initial ethanol concentrations. From the experiments, it could be found that with the initial concentrations of 10, 32, 72 and 84%v
