Feasibility of Batch Reactive Distillation with Equilibrium-Limited Consecutive Reactions in Rectifier, Stripper, or Middle-Vessel Column. [PDF]

, 2011
A general overall feasibility methodology of batch reactive distillation of multireaction systems is developed to study all the possible configurations of batch reactive distillation.

Practical residue curve map analysis applied to solvent recovery in non-ideal binary mixtures by batch distillation processes [PDF]

, 2006
Batch distillation inherent advantages has initiated recent search for process feasibility rules enabling the separation of azeotropic or difficult zeotropic binary mixtures thanks to the addition of an entrainer.

Separation of water – formic acid – acetic acid mixtures in the presence of sulfolane

Тонкие химические технологии, 2019
In this paper, extractive distillation flowsheets for water–formic acid–acetic acid mixtures were designed. Flowsheets not involving preliminary dehydration were considered, and the relative volatilities of the components in the presence of sulfolane ...

Generalised model for heteroazeotropic batch distillation with variable decanter hold-up [PDF]

, 2013
A general model of batch heteroazeotropic distillation is proposed. Both liquid phases present in the decanter can be refluxed or withdrawn as distillate, their hold-up can be increased, decreased or kept constant, as well. By assuming maximal separation,

Comparison of Extractive and Heteroazeotropic Distillation of High-Boiling Aqueous Mixtures

ChemEngineering, 2022
The processes of extractive distillation and heteroazeotropic distillation of mixtures containing water and a high-boiling component (propionic acid, acetic acid, 1-methoxy-2-propanol) are compared.

Isopropyl Alcohol Purification through Extractive Distillation using Glycerol as an Entrainer: Technical Performances Simulation and Design

Jurnal Bahan Alam Terbarukan, 2019
Isopropyl alcohol is widely used as industrial chemical intermediates and common solvents in households, pharmaceuticals, food, cosmetics, and medical purposes. The high purity of isopropyl alcohol requires special separation from its impurity i.e. water

Extracting the Essence of Distillation [PDF]

, 2010
In this paper, we give a re-formulation of our previously defined distillation algorithm, which can automatically transform higher-order functional programs into equivalent tail-recursive programs. Our re-formulation simplifies the presentation of the transformation and hopefully makes it easier to understand.

Comparison of Extractive and Pressure-Swing Distillation for Separation of Tetrahydrofuran-Water Mixture

Chemical Engineering Transactions, 2017
Tetrahydrofuran (THF) is widely used in many processes as solvent or chemical intermediate. It is necessary to separate mixture of THF-water, because in most commercial production processes, THF is produced from its water mixture.

Application of Ionic Liquids in Extractive Distillation of Ethanol – Water System

Chemical Engineering Transactions, 2015
Extractive distillation is one of the most common processes used to separate components of azeotropic mixtures. Its most distinct constrains are the tremendous energy costs required to achieve a fluid phase system.
