METHODS OF SEPARATING SALTS AND SOLVENTS FROM WATER

摘要

Methods and apparatus for separation of one or more salts from water are described. The methods include addition of a water miscible solvent to the water, followed by separation of the precipitated salt in a slurry, and evaporation of the water miscible solvent from the slurry. The apparatus include a novel design for a wetted wall separator tube that allows the solids in the slurry to pass through while providing efficient evaporation of the water miscible solvent from the water.

1. A system for separating a solvent from an aqueous mixture, the system comprising:
(a) a separator including:
i. a housing having at least one wall defining an interior space, an open top end, and an open bottom end, wherein the at least one wall has an inner surface and an outer surface; andii. a contour disposed on, or in, or defined by, at least a portion of the inner surface of the at least one wall; (b) wherein a flow path for an aqueous mixture is provided by at least a portion of the contour and the inner surface of the at least one wall.
