Energy systems: exergy analysis and pinch optimisation
10.0 ECTS creditsThe course deals with the theory and application of important methods for the energy- and environment-related optimisation of technological systems, that is, the systematic search for the best solution given certain circumstances and a certain goal. Examples of systems to which the methods can be applied are municipal heating networks, refuse and recycling systems, the process industry, power heating plants, purification plants and national and international energy distribution systems.
The course comprises two modules:
Module 1 (6 ECTS cr): Thermodynamic methods for energy effectivisation: entropy generation minimisation
and exergy analysis. The general definition of exergy, Dead State, thermodynamic equilibrium, reference condition, extended system and immediate surrounding, entropy generation in interface, entropy, energy and exergy balance equations for closed and open systems, real work, useful work, surrounding work, and exergy as state function. Equations for energy content and exergy change for closed system, open system with stationary flow and heat exergy in the Carnot model. Exergy loss and energy efficiency (Second Law Efficiency) for technological processes and cycles. Exergy analysis for mixture and separation processes such as desalination and carbon dioxide separation. Exergy analysis for combustion processes.
Module 2 (4 ECTS cr): Basic concepts such as pinch temperature, minimal need of external heating and cooling, composite curves and GCC (Grand Composite Curve), exemplified through current research and literature. Examples which illustrate either the design of a new system or suggestions for improvements of an existing system.
Instruction is in the form of lectures, exercises, and supervision of a project assignment.
