A low-melting point, heat transfer fluid comprising a mixture of LiNO, NaNO, KNO, NaNOand KNOsalts where the Li, Na and K cations are present in amounts of about 20-33.5 mol % Li, about 18.6-40 mol % Na, and about 40-50.3 mol % K and where the nitrate and nitrite anions are present in amounts of about 36-50 mol % NO, and about 50-62.5 mol % NO. These compositions can have liquidus temperatures between 70&#xb0; C. and 80&#xb0; C. for some compositions.

Low-melting point heat transfer fluid

A low-melting point, heat transfer fluid made of a mixture of five inorganic salts including about 29.1-33.5 mol % LiNO, 0-3.9 mol % NaNO, 2.4-8.2 mol % KNO, 18.6-19.9 mol % NaNO, and 40-45.6 mol % KNO. These compositions can have liquidus temperatures below 80&#xb0; C. for some compositions.

A low-melting point, heat transfer fluid made of a mixture of four inorganic nitrate salts: 9-18 wt % NaNO, 40-52 wt % KNO, 13-21 wt % LiNO, and 20-27 wt % Ca(NO). These compositions can have liquidus temperatures less than 100 C; thermal stability limits greater than 500 C; and viscosity in the range of 5-6 cP at 300 C; and 2-3 cP at 400 C.

Disclosed is a method that achieves water desalination by utilizing and optimizing clathrate hydrate phenomena. Clathrate hydrates are crystalline compounds of gas and water that desalinate water by excluding salt molecules during crystallization. Contacting a hydrate forming gaseous species with water will spontaneously form hydrates at specific temperatures and pressures through the extraction of water molecules from the bulk phase followed by crystallite nucleation. Subsequent dissociation of pure hydrates yields fresh water and, if operated correctly, allows the hydrate-forming gas to be efficiently recycled into the process stream.
