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.
