ABSTRACT:
A method and device is presented for separating liquid mixtures using ultrasonic atomization and without subjecting the mixture to heat or thermal distillation. The process of ultrasonic separation does not involve liquid heating and saves up to 75% of the energy required as compared to thermal distillation. The method involves high throughput fixed bed atomizers with a specially designed carrier gas flow for aerosolization, extraction, and transport of mist. The mist richer in the desired component is then collected and condensed by electrostatic or other de-misting means. Repeated processes can achieve high separation efficiency. The efficiency of separation can be controlled by varying the ultrasonic frequency, power, and number of arrays, liquid surface tension and interfacial tension of mixtures.
