Batch Extractive Distillation with Light Entrainer [PDF]
, 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.

Journal of Nonlinear Science, 2014 The effect of weak chaotic forcing on stable periodic oscillations is investigated in this work. Consider a system of ordinary differential equations, which supports an asymptotically stable limit cycle. Suppose it is perturbed by a small term driven by a chaotic trajectory produced by another system, called a chaotic generator.

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

Comprehensive Evaluation of Distillation Methods for Water-Ethanol Separation: Energy, Exergy, and CO₂ Emission Analysis with Process Enhancement [PDF]
Chemical Process DesignAzeotropic distillation (AD) and extractive distillation (ED) are two conventional methods for separating azeotropic mixtures. However, these processes consume a high amount of energy like other distillation columns.
