Exergy analysis of several basic thermodynamic cycles in air separation processes

The paper describes in brief the concept of exergy and relevant calculation methods.Exergy analysis of several basic thermodynamic cycles in air separation processes is carried out so as to reveal the nature of these basic thermodynamic cycles in more deeper levels.Exergy analysis can throw light on the optimization of these thermodynamic cycles and the further decrease of irreversible losses.Applying these fundamental analysis methods to air separation processes as a whole will serve the function of guidance in improvement and optimization of the processes in a better way.
