While rate‐based models are available in commercial flowsheet simulation tools, packed distillation columns are still mostly designed based on the equilibrium stage model in combination with HETP values. In order to discriminate between both types of models in a simple way, this article proposes an algorithmic test, based on a geometric criterion for total reflux operation. Substantial differences are illustrated especially for wide‐boiling mixtures, while component‐specific mass transfer rates either increase or reduce the deviation. The derived results are validated by dedicated experiments.

多组分蒸馏的模型判别－总回流的几何方法

虽然在商业流程模拟工具中可以使用基于速率的模型，但填充蒸馏塔仍主要是根据平衡阶段模型结合HETP值来设计的。为了以一种简单的方式来区分这两种模型，本文提出了一种基于总回流操作的几何准则的算法测试。尤其是对于宽沸点混合物，显示出很大的差异，而特定于组分的传质速率则增加或减小了偏差。通过专门的实验验证了得出的结果。
