Flash evaporation of a fraction of the warm seawater by reduction of pressure below the saturation value corresponding to its temperature.
• Expansion of the vapor through a turbine to generate power.
• Heat transfer to the cold seawater thermal sink resulting in condensation of the working fluid.
• Compression of the non-condensable gases (air released from the seawater streams at the low operating pressure) to pressures required to discharge them from the system.
