Advanced exergy analysis of an aircraft gas turbine engine: Splitting exergy destructions into parts

open access: yesEnergy, 2015
Abstract Advanced exergy analysis of an aircraft gas turbine engine is presented in this paper. In this framework, the main exergy parameters of the engine components are introduced while the exergy destruction rates within the engine components are split into endogenous/exogenous and avoidable/unavoidable parts.

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

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
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.

Thermal analysis and optimization of a heat regenerator composed of two coupled moving bed heat exchangers [PDF]

open access: yes, 2008
This work presents a study to optimize the performance of a heat regenerator composed by two coupled moving bed heat exchangers (MBHE). A MBHE is used to recover heat, from a hot gas stream, and the other one is used to preheat an air stream.
