  • Production of energy by direct contact of water immiscible working fluid with hot or warm water to vaporize liquid working fluid, utilization of vapor to produce mechanical energy and direct contact of spent vapor with cold or cool water to condense same
    Patent number: 4009082
    Abstract: A low boiling water immiscible fluid containing two or more molecular species and having a variable boiling point is contacted in the liquid state with relatively hot or warm water such as surface sea water or geothermal water, thereby generating vapor of immiscible fluid (together with a certain amount of water vapor) which is used to drive a prime mover such as a gas turbine and thereby produce mechanical energy; the exhaust vapor from the prime mover is condensed by direct contact with a relatively cool or cold liquid aqueous phase such as deep sea water or water from a lake or stream or cooling tower to condense the vapor; and the condensate is recycled. Provision is made for ridding water discharged from the system of entrained and dissolved immiscible fluid. By countercurrent flow of the liquid phases and by suitable matching techniques greater efficiency is obtained. The invention is also applicable to heat pumps.
