Abstract
A hygroscopic power plant utilizes low salinity liquid (e.g., sea water having a salinity of about 4%) and a source of high salinity liquid (e.g., brine having a salinity of about 38%) for generating electricity. The plant includes a flash chamber to which liquid is supplied and within which water in the liquid is flashed into steam producing more concentrated liquid. A steam turbine is responsive to the steam for generating electricity and producing heat depleted steam. A condenser is provided to which high salinity liquid and the heat depleted steam are supplied for directly contacting the steam with the high salinity liquid whereby the steam condenses on the liquid producing diluted high salinity liquid. A regenerator is provided for evaporating water from the diluted high salinity liquid to produce the high salinity liquid supplied to the condenser. Apparatus is provided for combining the low sea water liquid with the concentrated liquid produced by the flash chamber to form the liquid supplied to the flash chamber.
