| 摘 要：对某医药产品生产过程中产生的含异戊醇和乙醇的废水设计精馏分离处理方案，实现废水预处理的达标。采用Aspen Plus 过程模拟软件对精馏系统进行模拟优化，对比Wilson、NRTL、UNIQUAC三种物性模型的预测准确性，综合判断UNIQUAC更适用水-乙醇-异戊醇体系。通过模拟分析理论塔板数与蒸发量的关系，确定理论板数为14，并通过模拟分析进料位置与蒸发量的关系，确定进料位置为第6块理论板。最后通过确定各流股在三元相图中的位置可知塔顶存在分相现象。 |

| Abstract：In this paper, a distillation plan for the separation of wastewater containing isoamyl alcohol and ethanol produced in the industrial process of a pharmaceutical product was designed to satisfy the standard of wastewater pretreatment. Aspen Plus process simulation software was applied in simulating and optimizing the distillation system. The prediction-accuracys of three physical models including Wilson, NRTL and UNIQUAC were compared. It was concluded that UNIQUAC was the most suitable one for water-ethanol-isoamyl alcohol system. Through simulation and analysis of the relationship between number of the theoretical plate and evaporation volume, the number of theoretical plate was determined to be 14, and through simulation and analysis of the relationship between feed location and evaporation, the feed location was at sixth theoretical plate. Finally, by determining the position of each stream in the three element phase diagram, it was known that there was a phase separation phenomenon on the top of the tower． |
