Exergy

In this paper design and analysis of energy, exergy, economic and the environmental impacts (4E) of direct twostage reverse osmosis (RO) system have been optimized for supplying Miarkelar water, north of Iran using multiobjective optimization. In this city, water has been provided for a period of 20

This work presents thermoeconomic design for a multi-effect evaporation–mechanical vapor compression (MEE– MVC) desalination process. Exergy and thermoeconomic mathematical models of the considered process units are developed and presented in this work. The design data of an existing MEE–MVC (1500 m

Several studies have demonstrated that the performances of combined cycle power plants can be optimised taking advantages of flue gas waste heat. However, despite the process advantages related to power cycle have been clearly identified no judicious use of flue gas heat to enhance performances in t

To reduce energy consumption in the buildings and minimize negative environmental impacts, it is necessary to determine the operating condition that provides optimum system performance. Entropy or exergy analysis can be used as a reliable tool for analyzing energy consumption and environmental impac

This paper relates to the energetic and exergetic analysis of single-, double- and triple-effect distiller driven by solar energy. Energetic analysis makes it possible to define an applicable zone of operation according to the following criteria: water rejection limit to 50%, maximum salinity limit

We present an analysis of energy and exergy utilization in the utility sector of Saudi Arabia by considering the sectoral energy and exergy flows for the years 1990–2001. Energy and exergy analyses were conducted for its two subsectors, namely power-only plants and power/distillation plants, and hen
