Abstract Comprehensive experiment of chemical engineering was essential for training students' innovative spirit and engineering practice ability. Taking separation of ethanol aqueous solution as an example, the experiments of vapor-liquid equilibrium measurement and extractive distillation process simulation were combined to form a comprehensive simulation experiment, involving the measurement method of vapor-liquid equilibrium of ternary system, regression and evaluation of the experimental data using thermodynamic models, the extractive distillation process simulation, the influences of some factors on the separation effect. This comprehensive experiment could deepen the students' understanding of theoretical knowledge, improve the level of experimental operation.Through this experiment, students could have a certain understanding of the industrial application of extractive distillation,which could improve the students' engineering practice ability. This experiment was benefit to the cultivation of applied talents.
