Abstract
A heat driven osmosis water and power generator consists of dilute hygroscopic solution flow loop, an air humidity exchanger, a condensation solution circulation pump, a pressure retarded osmosis exchanger, a pressure exchanger, an evaporation chamber, a recuperative heat exchanger, a concentrated solution circulation pump, a solution pressure differential turbine generator, a freshwater power turbine, a concentrated hygroscopic solution flow loop and condensed water reservoir. The pump circulates low concentration, dilute, hygroscopic solution between air humidity exchanger and osmosis exchanger. Moisture is absorbed into low concentration hygroscopic solution from air circulation through humidity exchanger. As solution circulates through osmosis exchanger, moisture is extracted through osmosis membrane by concentrated hygroscopic solution. Concentrated hygroscopic solution circulation pump circulates high concentration solution between pressure retarded osmosis exchanger and vaporization chamber. Solution flowing to and from vaporization chamber is maintained at a lower pressure than fluid circulating through osmosis exchanger.
