Exergy flows in industrial processes

Author

  • Wall, Göran

Abstract

The concept of exergy is defined and applied to industrial processes. We discuss system boundaries and problem definition. The exergy flows and losses for a pulp and paper mill and a steel plant and rolling mill are presented and the exergy losses are determined. The aim is to show the simplicity and value of using the concept of exergy when analyzing industrial processes and to develop conventions and standards within the field. Large losses revealed in an exergy treatment of a process should be seen as a challenge to achieve technical improvements, not as an insurmountable obstacle.
