Exergy

Exergy is a powerful analytical tool bridging the conceptual gap between the Second Law of Thermodynamics and applied engineering. This volume shows how it can be deployed in a range of scenarios from power plants to petroleum production and refining.

Bridging the gap between concepts derived from Second Law of Thermodynamics and their application to Engineering practice, the property exergy and the exergy balance can be a tool for analyzing and improving the performance of energy conversion processes. With the exergy analysis it is possible to evaluate the performance of energy conversion processes not only on a thermodynamics basis but also by including production costs and environmental aspects and impacts of the studied processes. This comprehensive approach of the use of energy has, as one of the most important feature, the identification of sustainable ways of energy resources utilization.

Based on the fundamentals of the exergy concept, its calculation, graphical representations and exergy balances evaluation, Exergy: Production Cost And Renewability describes the application of detailed exergy and thermoeconomic analysis to power plants and polygeneration systems, petroleum production and refining plants (including hydrogen production), chemical plants, biofuel production routes, combined production of ethanol and electricity, aircraft systems design, environmental impact mitigation processes and human body behavior.

The presented case studies aim at providing students, researchers and engineers with guidelines to the utilization of the exergy and thermoeconomic analysis to model, simulate and optimize real processes and industrial plants.

Includes case studies of real processes and industrial plants Enables readers to use exergy and thermoeconomic analysis to optimize their own processes Demonstrates the application of the second law of thermodynamics to engineering practices Includes supplementary material: sn.pub/extras
