Abstract
An aqueous solution is contacted with a hydrate-forming fluid at a temperature beneath the maximum temperature at which the hydrate-forming fluid forms a solid hydrate in the presence of the solution, and at a temperature at which the amount of dissolved material which is present in the original aqueous solution exceeds the solubility of the dissolved material in any solution remaining after the hydrate formation. In this case, a magma is formed from solid hydrate, solid dissolved material, any unreacted hydrate-former still present and any unreacted aqueous solution still present. Thereupon, there are separated: 1) the hydrate-former and at least a part of the aqueous constitutents of the solid hydrate and 2) at least a part of the dissolved material, producing an essentially hydrate-former-free product and any residual water still present. The separation is carried out by fractional sublimation and/or evaporation and/or elution.
