Distillation is one of the most common processes used to separate liquid mixtures of chemical species with differing boiling points. Simple distillation columns are a single column with two product streams; complex columns may have three or more product streams and smaller side columns. It is difficult to simulate a complex column without a good initial estimate of key parameters such as the number of equilibrium stages and the reflux ratio. The goal of this thesis is to develop a software package that models the minimum reflux ratio, minimum number of stages and the column profiles in complex distillation columns with side-stream columns.
