Multicomponent Distillation Configurations with Large Energy Savings

In industry, many separation processes involve the separation of multicomponent mixtures using distillation. There are many distillation configurations that can carry out the same overall separation process. These configurations use an equal number of distillation columns, but they differ significantly in energy consumption. Therefore a major challenge for a practitioner is the identification o...

Minimum Energy and Entropy Requirements in Multicomponent Distillation

We present new analytical expressions for minimum energy consumption (1 law) and minimum entropy production, or lost work (2 law), in complex distillation arrangements. These simple, but exact, expressions apply to ideal mixtures and an infinite number of stages, and the relative volatility is the only required component property. The simple Vmin-diagram is shown to be very useful in evaluating...

Logic hybrid simulation-optimization algorithm for distillation design

In this paper, we propose a novel algorithm for the rigorous design of distillation columns that integrates a process simulator in a generalized disjunctive programming formulation. The optimal distillation column, or column sequence, is obtained by selecting, for each column section, among a set of column sections with different number of theoretical trays. The selection of thermodynamic model...
