| 摘 要： | 提出了一种可用于间歇萃取精馏过程模拟计算的快捷模型－准稳态模型，并对该方法的数学模型进行了推导。用此方法对间歇萃取精馏过程中塔顶、塔釜浓度，各塔板温度随时间的变化进行模拟，其结果与实验值吻合较好。它具有计算精度高、计算速度快等优点。

| Abstract: | A quasi-steady-state model for batch extractive distillation was provided. This shortcut model can be used to simulate the temperature of all trays in batch extractive distillation, the composition concentration of the still and the top of the distillation column. The experimental results were in good agreement with those from the model. The results proved that the model had such advantages as high precision and fast calculation. |
