ABSTRACT:
The present invention provides a device and method for desalinating saltwater which utilizes a heatable vessel wherein is placed a sufficient quantity of a salt which will absorb water of crystallisation and which has a dissolution index of not higher than 10−24. Saltwater is then added to the vessel and brought into contact with the salt, so that the salt will bind water from the saltwater and form a crystal hydrate. The excess saltwater with salt concentrate is drained from the vessel. The salt which has absorbed water tom the saltwater and formed a crystal hydrate is then heated in the vessel, and the pure water from the crystal hydrate is released as water vapour, which is collected and cooled to obtain desalinated water.
