Simulation of extractive distillation for separating Acetonitrile-Toluene using Butyl Propionate as entrainer

open access: yesTeknika, 2023
Acetonitrile is known as a polar solvent that can dissolve in non-polar hydrocarbon liquids. As an example of a nonpolar solvent, toluene is one of the solvents that dissolves well in acetonitrile. If acetonitrile and toluene are mixed, a minimum boiling

Comparison of Flavonoids from Spina Gleditsiae by Response Surface Method and Orthogonal Design

open access: yesE3S Web of Conferences, 2019
In this paper, the effects of extraction temperature, extraction pressure and dosage of entrainer on flavonoids yield were studied. The optimal process determined by response surface method was extraction temperature as 48.52°, extraction pressure as ...

Effective lipid extraction from undewatered microalgae liquid using subcritical dimethyl ether

open access: yesBiotechnology for Biofuels, 2021
Background Recent studies of lipid extraction from microalgae have focused primarily on dewatered or dried samples, and the processes are simple with high lipid yield. Yet, the dewatering with drying step is energy intensive, which makes the energy input

Heterogeneous Distillation of theSystem Water-Acetic Acid- p-Xylene: Study of its Fluid Phase Equilibria, Micro-Pilot Column Experimental Results and Computer Simulation

open access: yesChemical Engineering Transactions, 2013
The separation of the binary mixture water-acetic acid by direct distillation is not suitable for industrial applications because of the presence of a tangent pinch on the pure water end.

Batch Extractive Distillation with Light Entrainer [PDF]

open access: yes, 2006
International audienceUse of a light entrainer in batch extractive distillation is justified when the mixture boils at a high temperature, or when an appropriate heavy or intermediate entrainer cannot be found.

Entrainer Recycle for Batch Heteroazeotropic Distillation

open access: yesChemical Engineering Transactions, 2017
The influence of entrainer (and off-cut) recycle are studied by dynamic simulation for a batch heteroazeotropic distillation (BHAD) process. For the dehydration of isopropanol, toluene is applied as entrainer (E).

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

open access: yesJurnal 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

Isopropyl alcohol recovery by heteroazeotropic batch distillation [PDF]

open access: yes, 2010
Solvent recovery is becoming a major issue in the pharmaceutical and specialty chemical industries. Solvent recovery by conventional batch distillation is limited by the frequent presence of azeotropes in the used solvent mixtures.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
