“…In that paper, an example of acetic acid dehydration system using toluene as intermediate entrainer was given. Rodriguez-Donis et al (2001b) presented simulated results for the same system using vinyl acetate as a light entrainer. Skouras and Skogestad (2004a,b) presented feasibility analysis and batch time requirements for the separation of ternary heterogeneous azeotropic mixtures in closed batch distillation-decanter hybrids.…”

Molar heat capacities of the pure samples of acetone, methanol and the azeotropic mixture composed of acetone, cyclohexane and methanol were measured by an adiabatic calorimeter from 78 to 320 K. The solid-solid and solid-liquid phase transitions of the pure samples and the mixture were determined based on the curve of the heat capacity with respect to temperature. The phase transitions took place at (126.16±0.68) and (178.96±1.47) K for the sample of acetone, (157.79±0.95) and (175.93±0.95) K for methanol, which were corresponding to the solid-solid and the solid-liquid phase transitions of the acetone and the methanol, respectively. And the phase transitions occurred in the temperature ranges of 120 to 190 K and 278 to 280 K corresponding to the solid-solid and the solid-liquid phase transitions of mixture of acetone, cyclohexane and methanol, respectively. The thermodynamic functions and the excess thermodynamic functions of the mixture relative to standard temperature of 298.15 K were derived based on the relationships of the thermodynamic functions and the function of the measured heat capacity with respect to temperature.

“…The economic optimization of the different separation structures results in the conclusion that the heuristic rule for ideal mixtures, that is, "easy separation first should be done and the complicated one should be made last", is valid also for such non-ideal mixtures. Rodriguez-Donis [10] gave three examples based on the separation of non-ideal azeotropic or close boiling point binary mixtures through heterogeneous batch distillation, which were simulated using a commercial batch distillation package. Experiments validate the simulated separation of a minimum boiling azeotropic mixture.…”

Tert-butyl alcohol and water form an azeotrope at normal pressure. Simple distillation cannot be used to separate these two components. In this article, a systematic study of the separation of tert-butyl alcohol-water mixtures with an entrainer by heterogeneous azeotropic batch distillation was performed. Based upon the thermodynamic behavior of the ternary mixtures, cyclohexane was chosen as the entrainer. It formed ternary and binary heterogeneous azeotropes with the original components. The process feasibility analysis was validated by using rigorous simulation with chemical process simulation software -HYSYS Plant 2.2 and DISTIL 4.1. Simulation results were then corroborated in a batch experimental column for the selected entrainer.
