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.

New double column system for heteroazeotropic batch distillation [PDF]
, 2009 A new double column system (DCS) operated in closed mode is suggested for heterogeneous batch distillation. This configuration is investigated by feasibility studies based on the assumption of maximal separation and is compared with the traditional batch

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 Both liquid phases present in the decanter can be refluxed or withdrawn as distillate, their hold-up can be increased, decreased or kept constant, as well.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,

Homogeneous Azeotropic Distillation: Entrainer Selection [PDF]
, 1991 We examine the simplest homogeneous azeotropic distillation sequence of industrial relevance, where we add an entrainer to a binary azeotrope in order to recover both azeotropic constituents as pure products.
