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...

Multi-effect distillation (MED) systems are considered to be the most energy-efficient thermal desalination methods. This paper introduces development of a novel system for performance superior MED same operating temperature limits. Such an unprecedented achievement was attained by upgrading heat source using chemical potential adsorption phenomena. The proposed Adsorption Heat Transformer (AHT...

Reliable production of freshwater and energy is vital for tackling two the most critical issues world facing today: climate change sustainable development. In this light, a comprehensive review performed on foremost renewable energy-driven polygeneration systems using thermal membrane desalination. Thus, designed to outline latest developments integrated desalination based multi-stage flash (MS...

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...

Desalination is commonly adopted nowadays to overcome the freshwater scarcity in some areas of world if brackish water or salt available. Different kinds technologies have been proposed last century. In this paper, state mainstream solutions reported, showing current commercial like reverse osmosis (RO), Multi-Stages Flash desalination (MSF) and Multi-Effect Distillation (MED), new frontiers re...

Qatar’s primary source of fresh water is through seawater desalination. Amongst the major processes that are commercially available on the market, the most common large scale techniques are Multi-Stage Flash distillation (MSF), Multi Effect distillation (MED), and Reverse Osmosis (RO). Although commonly used, these three processes are highly expensive down to high energy input requirements and ...

Utilization of fossil fuel for supplying of requires energy of desalination systems is common. On the other hand, solar energy is one of the high-grade energies in the world that can be found specifically in hot weather places. Therefore, utilization of solar energy for operation of desalination systems will reduce greenhouse gases and is a good alternative way. Common exergy analysis method (s...

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 tub...

This report presents a novel Advanced Multi-Effect Distillation (AMED) method that can enable the production of substantial quantities of low-cost desalinated water using waste heat from high temperature reactors (HTRs). Conventional MED systems can currently compete with reverse osmosis desalination in areas where energy costs are relatively low, such as the Middle East. Because AMED can perfo...
