Water desalination, Solvent, Edible oils, Waste heat, Membrane-free
Removal of salt from sea water to make it fit for drinking or agricultural and industrial use
Energy efficiency and large system size of water desalination facilities
This invention introduces a completely new approach of water desalination. Certain solvents such as some edible oils and fatty acids possess an unusual characteristic of being able to dissolve water while not dissolving other water soluble substances such as sodium chloride. In addition, this quality of these selectively dissolving solvents enhances significantly with increasing temperature. This phenomenon is exploited to develop a novel process of membrane-free desalination of sea water without involving a phase-change of water using low quality heat. This heat can come from terrestrial heat sources or from the sun. It is also anticipated that in large systems, heat recovery will be used to improve the overall system efficiency.
