State Estimator Design for Multicomponent Batch Distillation Columns

I n the control of batch distillation columns, one of the problems is the difficulty in monitoring the compositions. This problem can be handled by estimating the compositions from readily available online temperature measurements using a state estimator. In this study, a state estimator that infers the product composition in a multicomponent batch distillation column (MBDC) from the temperatur...

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...

DEVELOPING A NEW INITIALIZATION PROCEDURE FOR DISTILLATION COLUMN SIMULATION

  The simulation of distillation columns is an essential step in design, optimization, and rating. In this paper, a new procedure has been proposed for the initial estimation of column profiles based on modified Kremser’s group method for simple and/or complex columns. The effect of this initialization algorithm on simulation procedure has been studied through two examples. The results show sig...

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...
