  • SYSTEMS AND METHODS FOR SEPARATING SOLUBLE SOLUTIONS
    Publication number: 20220267173
    Abstract: A system for separating a soluble solution includes a first freezer configured to receive a liquid feed stream and a refrigerant stream, and discharge a concentrated solution stream, wherein the first freezer is configured to exchange heat between the liquid feed stream and the refrigerant stream through direct contact within the first freezer and freeze a portion of the liquid feed stream, a first separator external to the first freezer and configured to separate ice particles from the concentrated solution stream and recirculate the concentrated solution stream to the first freezer, and a first ice washer coupled to the first separator and configured to receive the ice particles separated from the concentrated solution stream by the first separator and wash the separated ice particles to free the ice particles from contaminants.
