Abstract:
The present invention relates to a method of anhydrous ethanol production using circulation by multiple towers' alternation, the procedure includes the steps of heating, adsorption, internal circulation, vacuum suction, washing and resolving etc. The method can prolong the life of adsorbent, reduce the heat exchanger's surface, cooling water, the equipment investment and energy consumption, provide high ethanol recovery rate and high dehydration, and protect environment.
