In this section, only some important features of the Underwood method are addressed. Under the minimum reflux condition, Underwood developed sets of equations to calculate the minimum vapour flow rate. It assumes a constant relative volatility for each component throughout the column. It is impractical for useful operation, but they are valuable guidelines within which the practical distillation must be designed. It gives fast convergence of design solutions. The Underwood’s model serves as a good initializing design model for determining the minimum reflux for more complex distillation columns. Matlab is a fourth generation computer programming tool with highly interactive features making it user-friendly to its human users and other computer programming languages such as Java ®, FORTRAN, C/C++ and giving faster solutions to iterative and design problems. It integrates modern computation, visualization, and programming environment: it has sophisticated data structures, contains built-in editing and debugging tools, and supports object-oriented programming making it an excellent tool for teaching and research. Matlab is a high performance language for technical computing.

This work will help to show proof that developing a good computer design skill is very efficient, time-saving and is now an essential 21st-generation skill to acquire to fully specialize as a process design expert, as compared to depending on the cumbersome manual design approach as still practiced in many Nigerian universities. Many chemical engineers do not want to specialize in designing columns because of how hectic, boring and time wasting their calculations can be. To analyze the results obtained from the manual and computer shortcut design methods.
To obtain a computer based design and optimization of the Underwood’s shortcut model. To obtain initial reflux ratio manual design estimate for a plate distillation column, using Underwood’s shortcut model. Minimum reflux is an extreme operating condition for a distillation column, and can be approximated by Underwood’s method to obtain the minimum and optimum reflux ratio of the column for its optimization.
