Abstract
A new separation method, using ultrasonic atomization, for ethanol-water solution is discussed. This method has a high efficiency and separation ability, comparing with distillation. 100% ethanol is obtained from several mol.% ethanol-water solution, at 10℃ of solution temperature. And, more than 30℃, required energy for separation about 1/5〜1/7 comparing with distillation. Ultrasonic separation is not a thermal separation method, which will be used for separation, with avoiding thermal effects.
