Exergetic and exergoeconomic analysis of a renewable polygeneration system and viability study for small isolated communities

Application of advanced thermodynamics, thermoeconomics and exergy costing to a Multiple Effect Distillation plant: In-depth analysis of cost formation process

“…In multiple-product facilities, like cogeneration or trigeneration plants, calculating a thermodynamically rational cost for each product provides a reasonable basis for price assignment. In a recent paper by Calise et al [17], for a solar polygeneration system producing hot water for space heating in winter, cold water for space cooling in summer, electricity and desalted water for an insulated community [18], the exergoeconomic analysis allowed the authors to assign rational prices to each product and to build up a flexible tariff structure following the generation costs that evidently vary throughout the year with the solar radiation available; b. In many energy conversion systems, like power plants and refrigeration cycles [19,20], calculating a rational monetary value for each material stream has been proven useful to detect anomalies or malfunctioning components (whose unit cost of output temporarily increases) or for "what if analyses" (i.e.…”

Exergy analysis and thermoeconomic cost accounting of a Combined Heat and Power steam cycle integrated with a Multi Effect Distillation-Thermal Vapour Compression desalination plant

“…In [3] the potential integration of renewable sources and either thermal or mechanical desalination processes is discussed, focusing the attention on solar stills, multi-stage flash, multiple-effects boiling, reverse osmosis and electrodyalisis. An analysis of the potential for highly integrated solar energy systems to supply the requests from isolated communities is presented in [4]. In [5] the attractiveness of Concentrating Solar Power schemes integrated with thermal or mechanical desalination systems was investigated, in terms of levelized water cost and for possible application in Middle East and North Africa countries.…”

Exergetic Analysis of a Novel Solar Cooling System for Combined Cycle Power Plants

“…Additional algorithms are implemented in order to calculate the most common exergy performance parameters (exergetic efficiency, efficiency defect, etc.). This is a well-established and reliable approach, which was successfully used by the authors for several systems [20][21][22][64][65][66][67]. It is worth noting that the majority of the components included in the system do not involve chemical reactions.…”

“…In fact, the few works cited before regarding similar SACC system only address the energetic balances, neglecting to investigate the sources and the magnitude of the irreversibilities within the plant. Such analysis can be efficiently performed by implementing the well-known technique of the exergy analysis which combines the first and second laws of thermodynamics in order to better analyze irreversibilities [20][21][22]. Exergy analysis was diffusely used in literature in order to investigate the sources and magnitudes of irreversibilities in both solar heating and cooling systems and combined cycle power plants.…”
