Title:
REMOVAL OF DISSOLVED SALTS USING A SOLVENT
Document Type and Number:
WIPO Patent Application WO/2014/197865
Kind Code:
A3
Abstract:
A method and apparatus for reducing a salt concentration in a liquid composition use a solvent. The method includes combining the liquid composition and the solvent, where the solvent has lower carrying capacity for at least one salt in solution with the liquid composition. The liquid composition may be miscible with the solvent. The solvent may also have a lower boiling point than the liquid composition. The method includes precipitating some of the salt out of the liquid and removing the precipitate. The solvent may then be separated, leaving the liquid composition with a reduced salt concentration. The solvent may be reused if recovered after separation. The apparatus includes elements for implementing the method.
