CAMD for Entrainer Screening of Extractive Distillation Process Based on New Thermodynamic Criteria [PDF]

open access: yesChemical Engineering Transactions, 2018
This paper presents a framework for finding homogeneous entrainers E to separate non-ideal mixtures AB by extractive distillation. The framework is a systematic approach to convert a Computer Aided Molecular Design into a mixed integer non-linear program

Extractive distillation of the benzene and acetonitrile mixture using an ionic liquid as the entrainer

open access: yesGreen Energy & Environment, 2021
The benzene and acetonitrile azeotropic mixture was proposed to be separated by extractive distillation using an ionic liquid (IL) as the entrainer. The suitable IL was selected by the COSMO-RS model, and 1-ethyl-3-methylimidazolium tetrafluoroborate ...

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

open access: yesChemEngineering, 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.

Recent Advances in Extractive Distillation

open access: yesEngineering Proceedings, 2023
Distillation is widely recognized as the preferred method for separation due to its operational and control benefits. Traditional distillation processes, however, cannot successfully separate azeotropic mixtures with near boiling points. Numerous special

Wheat germ oil extracted by supercritical carbon dioxide with ethanol: Fatty acid composition

open access: yesGrasas y Aceites, 2016
In this work, supercritical fluid extraction (SFE) using CO2 with ethanol as entrainer was performed at a temperature of 40 oC under a pressure of 21 MPa. For comparison, a similar extraction without the entrainer was carried out. The extraction yield of

Comparative analysis of isopropyl alcohol dehydration using ionic liquids and deep eutectic solvent

open access: yesJournal of Ionic Liquids, 2023
The current article deals with the separation of the azeotropic mixture of isopropyl alcohol (IPA) and water using an ionic liquid, 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM][BF4]) and Deep Eutectic Solvents (DESs), Choline Chloride/glycerol ...

New extractive configuration separating azeotropic mixture in semi-batch way [PDF]

open access: yes, 2006
A new variant of batch extractive distillation, the so-called inverse-fed batch extractive distillation is presented. The total amount of the entrainer is pre-loaded to the boiler, and the mixture charge to be separated is continuously fed to the column ...
