A New Methodology to compute Exergy Cost. Part I: The Flow-Process Model

The exergy cost theory was proposed by Valero et al. (1986) in their "General theory of energy saving". This theory has been recognized as a powerful tool in the analysis of energy systems, and it has been applied to the assessment of alternatives for energy saving, local optimization, and thermoeconomic diagnosis. The paper introduces a new methodology, based on productive linear models, which provides new and more efficient algorithms to determine exergy costs and to analyse the cost formation process of products and wastes. This methodology consolidates the mathematical foundations of exergy cost theory and enhances the computer implementation of the thermoeconomic model. The keystone of this new approach is the Flow-Process table, which describes the relationship “Processes uses flows to produce flows”, and characterizes the productive and dissipative structures of an energy system.

Thermodynamics for Sustainable Management of Natural Resources

Cover Thermodynamics

Wojciech Stanek (Editor)

This book examines ways of assessing the rational management of nonrenewable resources. Integrating numerous methods, it systematically exposes the strengths of exergy analysis in resources management.

Thanatia: The Destiny of the Earth's Mineral Resources

Cover Thanatia

A Thermodynamic Cradle-to-Cradle Assessment by (author): Antonio Valero Capilla and Alicia Valero Delgado

Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today.
