  • Method and system for separation of solute from an aqueous solution
    Patent number: 8454926
    Abstract: Disclosed is method for separating solute from an aqueous solution comprising providing a first aqueous solution substantially saturated with solute, contacting the first aqueous solution with a clathrate former under conditions sufficient to form clathrates and to precipitate the solute from the first aqueous solution, separating solute from the clathrates by removing a first stream comprising clathrates and solute, and removing a second stream comprising solute, decomposing the clathrates into the clathrate former and a second aqueous solution, the second aqueous solution comprising solute in a concentration less than the concentration of solute in the first aqueous solution, and recycling the second aqueous solution by contacting said solution with a source for the solute to form a third substantially saturated aqueous solution for use as, or in combination with, the first aqueous solution, wherein the method is continuous.
