Experimental validation of an equilibrium stage model for three-phase distillation
Distillation and Absorption, Maastricht, 8-10.9.1997, 149-155
An experimental study with ethanol/water/cyclohexane has been carried out at a laboratory tray column in order to validate the equilibrium stage model for three-phase distillation columns. Composition profiles were measured both at total reflux and in the production case. Comparisons of experimental data with simulation results show generally a good agreement and an overall column efficiency of about 70% but also indicate kinetic phenomena motivating the development of detailed nonequilibrium models.
