Separation process through ultrasonic atomization is now in practical step. This process has many merits in comparison with distillation process: i) driven under normal temperature, ii) low energy consumption, iii) high separation efficiency and iv) low CO_2 and heat exhaust. We will show new data for the optimal operating conditions of the separation process. The discussion points are 1) High atomization velocity, 2) Complete dehydration of feed fermented ethanol solution, 3) Low energy consumption. This process is consisted of atomizer with ultrasonic oscillators, demister, air pump, energy saving cooler and molecular sieve adsorbents. We investigated each elemental process properties for atomizer, demister, cooler and PSA system. In results, we obtained several key points; 1) The energy consumption was 1/10 of vaporization energy, 2) The adsorption heat of water or ethanol to adsorbents was useful for heating of draft air into atomizer, 3) The optimal adsorbents volumes corresponding to atomization scale were determined, 4) The atomization velocity was accelerated by reduce of pressure in atomizer, and collection area should be under pressed condition.
