Performance comparison of pressure swing adsorption and amine‐based absorption for synthesis gas purification

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 5012-5027, September 2026.
Comparison of PSA and amine‐based absorption for syngas purification shows that PSA offers lower energy intensity, global warming potential, and minimum selling price, making it a more sustainable option. However, absorption achieves higher syngas purity. A GREENSCOPE‐based multi‐criteria assessment guides optimal process selection.

Gradient‐Based Optimization Modeling of Total Entropy and Heat Transfer in Exothermic Blood Analog Gold Nanoparticle Suspension

Engineering Reports, Volume 8, Issue 9, September 2026.
This study develops a gradient‐based multi‐start Nelder–Mead optimization framework for Casson‐micropolar blood‐analog nanofluid flow with gold nanoparticles in a convectively heated, exothermic microchannel, motivated by photothermal drug delivery. Spectral collocation solves coupled momentum, microrotation, and energy equations, from which entropy ...

Techno‐Economic Analysis and Multi‐Objective Optimization of a Novel Combined Cooling and Power System Driven by Geothermal Source and Waste Heat From Data Center

Energy Science &Engineering, Volume 14, Issue 9, Page 4300-4315, September 2026.
A novel combined cooling and power generation system is proposed by integrating organic Rankine cycle (ORC) with an absorption heat transformer, which is driven by combining geothermal energy and data center's waste heat. The system using R601a yielded the best overall performance, achieving an exergy efficiency of 40.34% and an annual cost of 130.29 k$

Energy, Exergy and Cost of Exergy Destruction for Coal-Fired Boiler in the Beverage Industry

Journal of Renewable Energy and Smart Grid Technology
This paper performs an energy and exergy analysis based on data obtained from selected boilers in the beverage industry. The boiler output is 16 tons/h with a pressure of 8 bar, and the steam output is saturated vapor. A boiler is designed for coal - fired fuel (sub-bituminous coal) with an economizer (heat exchanger) for recovered waste heat.
