Software for Calculating the Generalized Distillation Limit and Distillation Boundaries

The software is designed to calculate the Generalized Distillation Limit (GDL), Pitchfork Distillation Boundary (PDB), Total Reflux Boundary (TRB), and Feed Distillation Line (FDL) for continuous distillation in trayed columns with a single feed and the products in the form of a saturated liquid or vapor. The GDL and the distillation boundaries demarcate, among others, the feasible separation region for a given feed composition and its thermodynamic state. The software is written in Matlab. Its use is described in the manual, and Excel files with sample data are attached.

本软件旨在计算连续精馏塔中单进料及饱和液体或蒸汽形式产品的广义蒸馏极限（GDL）、分叉蒸馏边界（PDB）、总回流边界（TRB）以及进料蒸馏线（FDL）。广义蒸馏极限与蒸馏边界，界定了一系列可能分离区域，其中包含了特定进料组成及其热力学状态。该软件采用 Matlab 编写，其使用方法详述于手册中，并附带包含示例数据的 Excel 文件。
