Circumventing an azeotrope is reactive distillation

open access: yes, 2000
Using a McCabe-Thiele diagram, we explain nonintuitive behavior in a binary reactive distillation column where we react and separate two isomers displaying a maximum boiling azeotrope.

Waste Lignocellulosic Biomass as a Source for Bioethanol Production

open access: yesSustainable Chemistry
Synthetically produced biofuels play a critical role in the energy transition away from fossil fuels. Biofuels could effectively lower greenhouse gas (GHG) emissions and contribute to better air quality.

Design and Optimization of a Double‐Column Vapor Recompression Heat Pump Distillation Process via NSGA‐II for Separating Ternary Wide‐Boiling Mixtures

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a novel double‐column vapor recompression heat pump (DCVRHP) distillation process for separating ternary wide‐boiling‐range mixtures under two different vapor conditions: n‐hexane/n‐heptane/n‐octane using low pressure steam and n‐hexanol/n‐octanol/n‐decanol using high pressure steam.

Salt-added method for breaking azeotrope of binary IPA-water system : using aspen plus [PDF]

open access: yes, 2008
Distillation process is a method for separating various components of a liquid solution depending upon the distribution of these components between a vapour phase and a liquid phase.

Nichtlineare Staubungsneigung binärer Schüttgutmischungen: Herausforderungen bei der Prognose Non‐linear dusting tendency of binary bulk material mixtures: Challenges in prognosis

open access: yesChemie Ingenieur Technik, EarlyView.
Aufgrund überlagerter oder konkurrierender Mechanismen sind relevante Wechselwirkungen bei der Staubung von Schüttgutmischungen komplex und nur unzureichend verstanden. Selbst für Mischungen aus umfassend charakterisierten Einzelkomponenten existieren keine belastbaren Modelle. In dieser Arbeit werden die Hürden bei der Prognose thematisiert.

Separation of Acetone/Isopropyl Ether/Water Ternary Mixture via Hybrid Azeotropic-Extractive Distillation

open access: yesChemical Engineering Transactions, 2017
An industrial ternary mixture of acetone/isopropyl ether/water forms two binary azeotropes and a ternary azeotrope at atmospheric pressure and conventional distillation processes cannot achieve efficient separation.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Breaking Azeotropes by Azeotropic and Extractive Distillation in a Dividing-Wall Column

open access: yesChemical Engineering Transactions, 2013
This study gives a brief overview about using dividing-wall column (DWC) technology in azeotropic and extractive distillation processes aimed to break azeotropes. The relevant case study considered here is the bioethanol dehydration process that requires significant energy to overcome the azeotropic behaviour of ethanol-water mixture.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
