ABSTRACT:
A process for simultaneously generating power and recovering potable water from a source of salinous water-- e.g. ocean and/or sea water. A first portion of salinous water, from the surface of the source, or from a colder, deeper depth, is increased in temperature via indirect contact with a plurality of non-salinous vaporous phases (i) derived from the salinous water and, (ii) obtained therefrom at an elevated temperature and a subatmospheric pressure. The warmed salinous water is further increased in temperature by being maintained in a solar radiation heat sink and exposed therein to radiant solar energy to increase its temperature to a level within the range of about 135.degree. F. to about 210.degree. F. Heated salinous water is introduced into a plurality of vacuum flash separation zones, each succeeding one of which is maintained at a lower absolute pressure. At least one of the resulting vaporous phases is passed into and through a turbine, from the resulting motion of which power is generated. The remaining vaporous phases, and at least two, are successively used to preheat the first salinous water portion prior to the introduction thereof into the solar radiation heat sink. Exiting vapors from the turbine and the vaporous phases employed in the salinous water preheat system are cooled and/or condensed via indirect contact with a second salinous water portion to recover potable water.
