Exergetic Analysis of a Cryogenic Air Separation Unit. [PDF]
Entropy (Basel), 2022 This case study analyzes a cryogenic air separation unit (ASU) with a production of V˙O2=58,300 [m3Nh] of gaseous oxygen with a concentration greater than 98.5%, operating in Romania on a steel plant platform. The goal of the paper is to provide an extensive model of exergetic analysis that could be used in an optimization procedure when decisional ...

Thermodynamic and Exergetic Analysis of the Allam Cycle
Global Journal of Energy Technology Research Updates, 2021 This paper presents the study on the current developments of oxy-combustion thermodynamic cycles, which use the CO2 produced by combustion within the cycle itself without releases into the atmosphere. This is the cause of the attention paid to this type of technology and which makes these cycles one of the avant-gardes of power plants.
