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.

本软件用于计算单股进料、产物为饱和液体或蒸气的板式精馏塔的连续精馏过程所涉及的广义精馏极限（Generalized Distillation Limit, GDL）、叉形精馏边界（Pitchfork Distillation Boundary, PDB）、全回流边界（Total Reflux Boundary, TRB）以及进料精馏线（Feed Distillation Line, FDL）。广义精馏极限与精馏边界等可划定给定进料组成及其热力学状态下的可行分离区域。本软件采用Matlab语言编写，其使用方法详见配套手册，附带的Excel文件包含示例数据。
