Bio-ethanol, as a clean and renewable fuel, is gaining increasing attention, mostly through
its major environmental benefits. It can be produced from different kinds of renewable …

Extractive distillation processes enable the separation of non-ideal mixtures, including
minimum or maximum boiling azeotropes and low relative volatility mixtures. Unlike …

Throughout history, distillation has been the most widespread separation method. However,
despite its simplicity and flexibility, distillation still remains very energy inefficient. Novel …

The separation of the ternary nonideal system ethyl acetate (EtAC)/ethanol (EtOH)/water
with multiazeotropes is very important since they are always generated in the production …

In spite of claiming around half of the operational costs of chemical plants, distillation is still
the most popular separation technology. Distillation has low thermodynamic efficiency …

The purification of bioethanol fuel involves an energy-intensive separation process to
concentrate the diluted streams obtained in the fermentation stage and to overcome the …

This study introduces a novel approach to the initial design of bioethanol dehydration,
incorporating process fluctuations. Unlike previous studies, which overlooked fluctuations …

Extractive distillation is an effective method for separating azeotropic or close boiling point
mixtures by adding a third component. Various technologies for performing the extractive …

Syngas fermentation is used industrially to produce diluted bioethanol (about 1–6 wt%). This
research study proposes a novel downstream process that recovers bioethanol in an energy …

The extractive dividing wall column (EDWC) has received more and more attention because
of the advantages of energy saving and high efficiency for separating mixtures with multiple …
