化工专业综合性实验“分离乙醇水溶液”的探究

Research on Chemical Engineering Comprehensive Experiment:Separation of Ethanol Aqueous Solution

化工专业综合性实验对于培养学生的创新精神和工程实践能力至关重要。以分离乙醇水溶液为例，将气液相平衡测定实验和萃取精馏过程模拟相结合形成综合性实验，涉及到了三元体系的气液相平衡测定方法、实验数据采用不同热力学模型的回归及评价、萃取精馏过程模拟、各因素对分离效果的影响评价等。加深了学生对理论知识的理解，使学生对萃取精馏工业应用有了一定的认识，提高了学生的实验操作水平和工程实践能力，为应用型人才的培养提供了有力保障。

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, in- volving the measurement method of vapor-liquid equilibrium of ternary system, regression and e valuation of the experimental data using thermodynamic models, the extractive distillation process simulation, the influences of some factors on the separation effect. This comprehensive experi- ment could deepen the students＇ understanding of theoretical knowledge, improve the level of ex- perimental operation. Through this experiment, students could have a certain understanding of the industrial application of extractive distillation, which could improve the students＇ engineer ing practice ability. This experiment was benefit to the cultivation of applied talents.
