Special Issue Information

Dear Colleagues,

Exergoeconomics is a unique exergy-based method that identifies and calculates the location, magnitude, causes, and costs of thermodynamic inefficiencies in a thermal system. The real inefficiencies in such a system are the exergy destruction and the exergy loss. Through a comparison between investment cost and cost of exergy destruction, the researcher/designer can decide for each important component of a system whether (a) an increase in the efficiency at the expense of investment cost or (b) a decrease in the investment cost at the expense of the efficiency would increase the cost effectiveness of the overall system. In order to better understand the interactions among different components (by splitting the investment cost and the cost of exergy destruction into endogenous and exogenous parts) and the real potential for improving the system (by splitting the investment cost and the cost of exergy destruction into unavoidable and avoidable parts), an advanced exergoeconomic analysis has been developed and already successfully applied to several systems. The information obtained from these methods is very useful in developing strategies for improvement and in the optimization of thermal systems. The conclusions obtained from the analysis and optimization (iterative and mathematical) based on conventional or advanced exergoeconomic analysis cannot usually be obtained when exergetic and economic analyses are applied separately.

Research and review papers dealing with the development and/or application of exergoeconomic analysis, evaluation, and/or optimization are sought for this Special Issue.

The design of new dual-purpose thermal desalination plants is a combinatory problem because the optimal process configuration strongly depends on the desired targets of electricity and freshwater. This paper proposes a mathematical model for selecting the optimal structure, the operating conditions, and sizes of all system components of dual-purpose thermal desalination plants. Electricity is supposed to be generated by a combined-cycle heat and power plant (CCHPP) with the following candidate structures: (a) one or two gas turbines; (b) one or two additional burners in the heat recovery steam generator; (c) the presence or missing a medium-pressure steam turbine; (d) steam generation and reheating at low pressure. Freshwater is supposed to be obtained from two candidate thermal processes: and (e) a multi-effect distillation (MED) or a multi-stage flash (MSF) system. The number of effects in MED and stages in MSF are also discrete decisions. Different case studies are presented to show the applicability of the model for same cost data. The proposed model is a powerful tool in optimizing new plants (or plants under modernization) and/or improving existing plants for desired electricity generation and freshwater production. No articles addressing the optimization involving the discrete decisions mentioned above are found in the literature. Full article
