Abstract

This work consists of an experimental and theoretical survey of a distiller composed of three compartments of which the coolant fluid used is water. Distiller’s type is conceived for an adequate separation of constituent of a water-ethanol mixture of which the temperature of boiling point are lower than the hot water. The theoretical survey is based on a model of heat transfers between the compartments and coolants fluid and based on liquid-vapor equilibrium at the distiller. The results show notably that one can bring back the temperature of the fluid to distill around the temperature of boiling point of the mixture. In this paper, one could study the importance of the temperature of the hot water that is a parameter fundamental of the system and the one of debit of the fluid coolant acceptable for the distiller's good working.

Key words: Distiller, fluid coolant, boiling point temperature, numeric simulation.
