Abstract:
1. An apparatus for the extraction of a solvent from a first solution using osmosis comprising: a. a first chamber having an inlet and an outlet, the inlet of the first chamber being connected to a source of the first solution; b. a semi-permeable membrane separating the first chamber from a second chamber; c. the second chamber having an inlet and a first and second outlet; d. a third chamber having an inlet to receive a solvent-enriched second solution from the first outlet of the second chamber and a reagent from the second outlet of the second chamber and having an outlet; e. a filter for filtering the solvent-enriched second solution connected to the outlet of the third chamber, the filter having a first and second outlet, the first outlet is connected to the inlet of the second chamber in order to recycle a precipitated solute to the second chamber; and f. a fourth chamber receiving the solvent-enriched second solution from the second outlet of the filter, having a heater for heating a solvent-enriched second solution to decompose any remaining solute into its constituent gasses, a first outlet for returning the constituent gasses to the inlet of the second chamber, and a second outlet by which the final product exits the apparatus.
