Advanced exergy analysis of an oil shale retorting process [PDF]
Applied Energy, 2016 Abstract Fushun-type process is the most common method of oil shale retorting used in China. The process is, however, characterized by poor thermodynamic performance. While conventional exergy analysis is able to quantitatively determine exergy destruction in a system, identification of the sources of the exergy destruction, and thus identification ...

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