Passive solar desalination towards high efficiency and salt
A total efficiency of 354% was achieved alongside the success of salt rejection in each stage, indicating a new pathway for passive solar high-efficiency and salt-rejection desalination.
The heat from a heat-generating process is transferred to a heat transfer media and can be extracted later using a secondary power cycle. There are several types of facilities that use thermal energy storage with molten salts, such as concentrated solar power plants (CSP plants) or nuclear hybrid energy systems (NHES).
heat transfer and storage due to their ability to withstand tem-peratures above 900°C. The melting point and solidification point of heat transfer mate-rials are critical considerations in solar thermal power generation systems. Nitrate molten salt is currently widely used due to its low melting point of 220°C.
This work contains a review of some molten salt energy technology systems and the use of molten salt in advanced nuclear power systems. A 'salt' is an ionically bonded chemical, consisting of positively and negatively charged component ions. A typical example of a salt is sodium chloride (NaCl), commonly known as 'table salt.'
Molten salt is used for both thermal energy storage and power production. Thermal energy storage technologies include CSP plants, which use an array of reflectors to heat salt, which is subsequently stored for later use in a power cycle. MSRs also use molten salt for power production, operating using molten salt as a circulating fuel.
