Is exergy destruction minimization the same thing as energy efficiency maximization?

Journal of Energy Systems, 2021
This paper discusses whether the exergy destruction minimization or energy efficiency maximization comes first in resolving the climate emergency problem and provides sustainable solution options regarding the 2nd Law of thermodynamics. It has been shown that low-temperature district energy systems with renewable energy sources and waste heat are ...

Influence of the ambient temperature change on steam pressure reduction valve exergy destruction and exergy efficiency [PDF]

, 2019
The paper presents an exergy analysis of pressure reduction valve mounted in the steam propulsion system on conventional LNG carrier. From exploitation are obtained that the valve pressure and temperature decrease become as higher as steam system load increases.
