Abstract
AbstractIn the coming years, numerous regions are expected to suffer from water scarcity. One of the technologies of great interest in facing this challenge has been the generation of freshwater through water desalination, a process that reduces the amount of salt and minerals to a standard level, making the water suitable for drinking or agricultural/industrial use. The efficiency of each desalination process depends on the concentration of salts in the raw water and the end-use of the produced water. The present study presents the exergetic and exergoeconomic analyses of the coupling of a power plant with desalination units for the simultaneous generation of energy and water in Iran. The plant is integrated, first, with a multi-stage flash (MSF) unit and, then, with a multi-effect desalination (MED) unit. We find that the cost of exergy destruction of the MED and MSF integrated plants is lower when compared to the standalone power plant by about 0.1% and 9.2%, respectively. Lastly, the freshwater production in the plant using MED is significantly higher than that in the plant with MSF (1,000 versus 1,521 kg/s).
Highlights
Life, health, and sustainable development require freshwater
The present study evaluates the combination of a combined-cycle power plant with multi-effect distillation (MED) and multi-stage flash (MSF) desalination systems using an exergoeconomic analysis
We examined the detailed thermodynamic and exergy performance of the combined-cycle power plant, calculating the exergy of each stream and the exergy destruction associated with each piece of equipment
Summary
Health, and sustainable development require freshwater. Humans need water resources such as rivers, lakes, and aquifers to meet the needs of drinking, agriculture, and industry. There are two main problems with the use of these freshwater sources: river and lake pollution from domestic and industrial waste and wastewater, and non-uniform distribution of water in the different parts of the world. An energy cost evaluation between the integration of multi-stage flash (MSF), multi-effect distillation (MED), and reverse osmosis (RO) with a simple cycle oilfired power plant (OFPP) and a combined-cycle power plant was realized. They achieved maximum production of power and water using a mathematical model and showed that thermal desalination can improve the overall efficiency of the plant (Ihm et al ). Hosseini et al ( ) focused on the optimum integration of a combined-cycle power plant with an MSF water desalination unit from economic, exergetic, environmental, and reliability points of view
