Powering desalination by waste heat is often proposed to mitigate energy consumption and environmental impact; however, thorough technology comparisons are lacking in the literature. This work numerically models the efficiency of six representative desalination technologies powered by waste heat at 50, 70, 90, and 120 ◦C, where applicable. Entropy generation and Second Law efficiency analysis a...

integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. a new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. the proposed system includes evacuated tube so...

Countries which do not have adequate supply of freshwater sources like Kuwait resort to using desalination plants to meet their demand. Kuwait had used Multi-flash desalination (MSF) plants sine the 50’s of the last century to satisfy its ever increasing demand. Many new and more efficient and cost effective desalination technologies are currently available. Kuwait is in the process of building...

Ocean thermocline energy is a sustainable and reliable heat source for seawater desalination in remote islands that has no access to primary energy. To adapt the unique features of energy, i.e., sensible with small temperature gradient, we propose novel system combining direct-spray technology multi-effect distillation (MED). The steam generator conventional MED replaced by tubeless spray evapo...

The escalating freshwater demand is stimulating the researchers to optimize performance of desalination technologies. current study presents exergoeconomic optimization a forward feed multi-effect (FF-MED) system under two configurations i.e., conventional MED and with energy recovery (MED-ER). A detailed numerical model concerning energy, exergy, component-based analysis employed estimate cons...

Multi-effect distillation with thermal vapor compression (MED-TVC) is a highly energy-efficient desalination technology that can provide reliable and sustainable source of high-quality water, particularly in areas limited energy infrastructure water resources. In this study, numerical model based on exergoeconomic approach developed to analyze the economic performance MED-TVC system for seawate...

In this paper, a new thermodynamic cycle for power and fresh water production is presented, which includes MED-TVC desalinations Allam cycles due to the important influence they have on electric industry in controlling limiting greenhouse emissions. First, analyzed appropriate location heat-extraction identified produce required vapor desalination system. It was determined that heat site suitab...
