A Short-Cut Design Technique to Batch Distillation Column

Multicomponent batch distillation column design

A Short Method for the Design of Reactive Distillation Column

In this study, a short method for the design of reactive distillation is presented. The method is based on distillation lines and tray-by-tray calculations, and a new strategy is suggested to locate the reflux ratio, the number of stages, and feed tray. The material balances are solved from the outside (top and bottom) to the inside of the distillation column (feed), to ensure that the product ...

Prediction of the Operating Conditions in a Batch Distillation Column Using a Shortcut Method

A shortcut procedure as quick, easy-to use method for design and simulation of multicomponent batch distillation is used to predict the operating condition of recovering xylene from solvent in an existing batch distillation column in benzol refinery. The procedure can be used to investigate the effect of the operating parameters on the operation of column for three possible modes of batch d...

New double column system for heteroazeotropic batch distillation

A new double column system (DCS) operated in closed mode is suggested for heterogeneous batch distillation. This configuration is investigated by feasibility studies based on the assumption of maximal separation and is compared with the traditional batch rectifier (BR). We study the configurations also by dynamic simulation based on a detailed model using a professional simulator. For the new c...

A Systematic Approach to Distillation Column Control

This paper presents a systematic approach to distillation column control. The main emphasis is on the steps which precede the actual controller design, namely the modelling of the column and the selection of the control con guration. By control con guration in this context we mean the two independent variables used for composition control (for example, L and V;D and V , or L D and V B ). The st...
