Multicomponent batch distillation column design

Thermal Integration of a Distillation Column through Side-exchangers

Invariant rectifying and stripping (IRS) curves are used for thermodynamic analysis of a distillation column. Thermal integration of a distillation column with the background process through side exchangers (side reboilers/condensers) is important for energy-efficient design of a distillation column. Thermal integration of a distillation column through side exchangers also improves the exergeti...

Measurement structure design for multicomponent distillation column with specific estimation objective

In this work, the problem of designing the estimation structure to infer some of the effluent compositions in a multicomponent distillation column is addressed, with the aim to determine the structure that yields the best estimator functioning in the sense of a suitable compromise between performance versus complexity, regardless of the particular estimation algorithm employed. The structure de...

Dynamic Modelling and Optimal Control of a Multicomponent Batch Packed Distillation Column

A dynamic model for the simulation of the batch operation of a multicomponent packed distillation column is developed. The accuracy of simulation code is verified by using two types of mixtures (cyclohexane-n-heptane-toluene and ethanol–water) theoretically and experimentally. An optimum internal reflux ratio profile is searched to maximize the distillate amount of a specified concentration for...

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...
