Exergy as a means for process integration in integrated steel plants and process industries

摘要

Exergy analysis can be a useful tool for process comparison and improvement in industrial energy systems. Examples from three branches are given: pulp and paper, bio refineries (ethanol) and steel production. The application and development of exergy analysis in an integrated steel plant is shown together with description and explanations on destroyed and lost exergy. Implementation for energy conservation and use as a pedagogic tool is discussed.
