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 ...

Design of optimal waste heat recovery system for compressed air energy storage considering various system layouts and working fluid types

Case Studies in Thermal Engineering
Compressed Air Energy Storage (CAES) is a long-time electricity storage technology, whereas the low efficiency restricts its popularization. Recycling waste heat from interstage coolers can enhance performance of CAES, and organic Rankine cycle (ORC ...

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 ...

Improving the performance of booster heat pumps using zeotropic mixtures [PDF]

Energy, 2018
Abstract This study demonstrated an increase in the thermodynamic performance of a booster heat pump, which was achieved by choosing the working fluid among pure and mixed fluids. The booster heat pump was integrated in an ultra-low-temperature district heating network with a forward temperature of 40 °C to produce domestic hot water, by heating part

Thermo-Economic Optimization and Resilience Analysis of Low-GWP Zeotropic Mixtures for Low-Enthalpy Geothermal Power Generation

Energies
The efficient recovery of low-enthalpy geothermal resources (T≤150 °C) faces significant thermodynamic limitations due to thermal mismatch in evaporators when pure fluids are utilized. This study investigates low-GWP zeotropic mixtures (Pentane/Isobutane)

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 ...

A Comprehensive Study on Hydrogen Production via Waste Heat Recovery of Gas Turbine Cycles in Cogeneration Power‐Hydrogen Layouts: 4E Study and Optimization

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The efficient utilization of waste energy in gas turbine (GT) cycles (GTCs) is a crucial aspect of sustainable energy production. While previous studies have explored various aspects of waste energy recovery, a comparative analysis of different bottoming configurations has been lacking.
