Abstract
Method and apparatus for continuously freezing and melting a fluid mixture, for use in separating a fluid mixture into dilute and concentrated components which have been made separble due to the freezing. A turbine is used to produce mechanical energy to drive a refrigeration compressor, while exhaust heat from the turbine is used for secondary cooling. Heat from a refrigeration condenser is used to melt the liquid frozen by a refrigerant evaporator. The evaporator and condenser may comprise a plurality of plates or may comprise a bubbler for bubbling refrigerant directly into contact with the fluid mixture.
