Modern Method of Generating the Best Control Structure for Binary Distillation Columns

A Survey for the Selection of Control Structure for Distillation Columns Based on Steady State Controllability Indexes

Application for Testing Control Configurations of Binary Distillation Columns

The paper addresses the problem of testing various control configurations for binary distillation columns. Analyzing from plantwide control point of view the place of distillation column within the plant, the result will be the best control configuration. The proposed application Test BCC is a very useful tool to evaluate the resulted control configuration for distillation columns. First, it is...

Selection of Control Structure and Temperature Location for Two-product Distillation Columns

The choice of control structures for distillation columns is important for practical industrial operation. There is no single ‘best’ structure for all columns, so some authors feel that each column should be treated independently. Nevertheless, the objective of this work is to find a structure that is ‘reasonable’ for all columns. In this paper, we consider the steady-state deviations in produc...

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 Simulation of Distillation Sequences in Dew Pointing Unit of South Pars Gas Refinery

The understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. This paper reports a dynamic simulation study of the possible distillation columns sequences of Dew pointing unit in the second phase of South Pars Gas Refinery. In this unit, three columns are u...
