ABSTRACT:
A low boiling, water soluble organic solvent is added to a saturated brine to thereby reduce the salt solubility of the brine and cause precipitation of the salt. The precipitated salt is filtered out and dried. The remaining brine-solvent mixture is distilled to remove the solvent which is reused. Unsaturated brine that is generally free of solvent is returned for resaturation with salt.
