McCabe-Thiele and Ponchon-Savarit Methods of Analysis of Distillation Columns with MATLAB

Overview

This project presents a comprehensive MATLAB implementation of two fundamental distillation column analysis methods: McCabe-Thiele and Ponchon-Savarit. The goal is to provide a fast, precise, and versatile tool for calculating various distillation column specifications under different input conditions.

Key features of the project include:

  1. Calculation of top and bottom stream flows
  2. Determination of optimal feed stages
  3. Computation of minimum stages and reflux ratio
  4. Calculation of the number of theoretical stages
  5. Handling of various input specifications including feed flow characteristics, R/R_min, and composition of top and bottom streams
  6. Robust exception handling for invalid input specifications
  7. Interactive graphical user interface for the McCabe-Thiele method

The project demonstrates advanced MATLAB programming skills, a deep understanding of chemical engineering principles, and the ability to create user-friendly tools for complex engineering calculations.
