DSE desalination employing TSILs. (a) Saline water mixes with IL; (b) Upon heating, IL draws water out of saline while leaving the salts in the water phase, yielding a high salinity brine (MX); (c) Brine is separated from the water-in-IL solution; (d) A reduction in temperature leads to decreased solubility of water in IL, resulting in dissolution; (e) Fresh water is separated from the IL phase, and the IL is recycled for subsequent process turnover of the DSE cycle.
