Synthesis of heat‐integrated thermally coupled nonsharp distillation using self‐adaptive spherical search

AIChE Journal, Volume 71, Issue 7, July 2025.
Abstract Although thermally coupled distillation (TCD) exhibits strong energy efficiency, the possibility of utility cost savings remains debatable. TCD designs that do not consider vapor transport can underestimate costs, making section rearrangement crucial to find more operable configurations.

Generalized optimization framework for synthesis of thermally coupled distillation columns

AIChE Journal, Volume 71, Issue 6, June 2025.
Abstract In this article, a generalized optimization framework is proposed for the synthesis of thermally coupled distillation systems within an equation‐oriented environment. The proposed framework consists of three components: an efficient superstructure representation, a novel mathematical formulation, and the associated solution algorithm ...

Advanced downstream processing for sustainable ethyl acetate production by fermentation

AIChE Journal, Volume 71, Issue 3, March 2025.
Abstract Ethyl acetate is a platform chemical conventionally obtained through fossil fuel routes, but more recently its production by fermentation from carbohydrates has been scaled up to a pilot scale. Yet, the complexity of downstream processing (low product concentrations in liquid broth and in off‐gas, azeotrope formation, and the presence of ...

Hygroscopic cycle for enhanced water efficiency in thermal power plants

Environmental Progress &Sustainable Energy, Volume 44, Issue 2, March/April 2025.
Abstract This article presents a methodology for calculating the potential for water savings when replacing the Rankine cycle with the hygroscopic cycle in power plants. The savings were analyzed in thermal power plants with different generating units (diesel, gas, steam, and combined cycle), different cooling systems (seawater open cycle, adiabatic ...

Energy, exergy and exergoenvironmental assessments of waste heat operated basic and modified cogeneration systems for freshwater and hydrogen production

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
The performance of four different configurations of waste heat‐driven organic Rankine cycle (ORC) integrated with reverse osmosis and Proton exchange membrane electrolyser is modelled in the current study. The four configurations of ORC are the basic (BORC), with internal heat exchanger (HORC), with mixing chamber (MORC), and with both internal heat ...
