Abstract
Spray distillation process as a novel process was developed to overcome the energy requirement of separation and purification of bioethanol. Unlike conventional distillation method that utilizes difference in boiling point to provoke phase change, spray distillation column utilizes the gradient concentration of ethanol contained in the droplets and the surrounding air to provoke transfer of compound out of the droplets. Previous study has developed a basic model of spray distillation and proven that the separation process could be achieved at relatively low temperature of 40oC. However, the basic model, which was based on classical mass, energy, and momentum balances could not describe the process in higher scale. This study aims to develop the better modelling of spray distillation process by taking into consideration vapor flux and diffusion model of throughout the column. The information is required to develop larger scale equipment which is more suitable to be further increased to actual industrial capacity. Modelling show that ethanol vapor travels in the opposite direction of the spray with the affecting variables: Velocity of counter current air (
