Exergy Analysis for Efficiency Improvement and Environmental Impact Mitigation

Plenary Speaker: 

Prof. Marc A. Rosen

Faculty of Engineering and Applied Science, Ontario Tech University

Oshawa, Ontario, Canada


The use of exergy analysis is described in the context of its applicability and usefulness for efficiency improvement as well as environmental impact mitigation. By addressing efficiency and environmental impacts, the talk aims to explain and illustrate the benefits of exergy in practice, and to allow these benefits to be appreciated more fully and realized by engineers and other practitioners.

As a thermodynamic method and tool, exergy analysis is particularly useful for the former, and allows efficiencies to be pinpointed that are always meaningful and rational. Exergy analysis also allows thermodynamic losses to be identified that truly measure deviation from ideality. These thermodynamic losses are also characterized through exergy analysis in terms of magnitude, location and cause. Exergy analysis thereby allows rational statements of the potential for improvement of any system, based on the laws of thermodynamics.

Exergy can be used to understand environmental impacts, such as climate change, and can provide measures and methods to assess and improve energy systems in terms of their environmental performances and behaviors.

More broadly, exergy analysis also can help better understand the benefits of sustainable energy by providing more useful and meaningful information than energy methods provide. This is in large part because exergy analysis clearly identifies efficiency improvements and reductions in wastes and environmental impacts attributable to sustainable energy. Another advantage of exergy analysis in terms of energy sustainability is that it can identify and assess better than energy the economic characteristics of energy technologies.

Examples and case studies are presented that illustrate and demonstrate the points raised in this talk, as a means of improving understanding as well as highlighting the potential of exergy analysis.

By addressing all of these points, this talk explains how and why exergy analysis should be applied in addressing efficiency improvement and environmental impact mitigation, either as a unique tool or as a as a complementary tool to more conventional methods and tools.
