The book "Practical Approach to Exergy and Thermoeconomic Analyses of Industrial Processes" offers a comprehensive introduction to exergy and thermoeconomic analyses of industrial processes. It is aimed at students, professionals, and practitioners involved in process analysis, power plant design, and fuel consumption optimization. The authors, Enrique Querol, Borja Gonzalez-Regueral, and Jose Luis Perez-Benedito, present an innovative methodology that covers both theoretical and practical aspects. By using Aspen Plus and a newly developed Microsoft Excel application, the application of theory to real-world problems is illustrated. Each chapter includes detailed explanations and numerous examples that guide the reader through complex cases and deepen the understanding of cost formation and fuel usage in industrial processes.
