摘　　要：精馏操作的必要条件是回流,回流比是重要的一项参数,合理的选择适宜回流比有助于精馏产品的质量和分离效果的提高,本文以乙醇和正丙醇混合物的精馏分离为例,分析不同回流量不同回流比对精馏操作的影响。Reflux is a necessary condition for distillation operation, and reflux ratio is an important parameter. Reasonable selection of appropriate reflux ratio is helpful to improve the quality of rectification products and separation effect. In this paper, the distillation separation of ethanol and n-propanol mixture is taken as an example to analyze the influence of different reflux flow and reflux ratio on distillation operation.
