萃取精馏实验是化学工程与工艺专业一个重要的综合性实验,该实验进行汽液平衡测定,萃取精馏实验操作,应用Aspen Plus软件的Data Regression进行汽液平衡数据回归得到UNIQUAC方程的交互作用参数,应用Flash模块进行闪蒸计算得到乙醇-水相对挥发度,应用RadFrac模块优化萃取精馏工艺参数及萃取精馏操作过程模拟,理论计算与实验操作相结合,激发了学生的学习兴趣,加深了学生对实验原理、 萃取精馏过程的理解,提高了学生解决复杂工程问题的能力.

Extractive distillation experiment is an important comprehensive experiment for Chemical Engineering and Technology specialty. In the experiment, measurement of vapor-liquid equilibrium and experimental operation of extractive distillation were carried out, data regression of Aspen Plus software was used to regress the vapor-liquid equilibrium data to obtain the interaction parameters of UNIQUAC equation. Flash module was used to calculate the relative volatility of ethanol-water. RadFrac module was used to optimize the process parameters of extractive distillation and simulate the operation p...
