Regasification plants vaporize liquefied natural gas using mainly high-pressure LNG pumps and heat exchangers. The vaporization pressure corresponds to the natural gas pipe line pressure. Due to the large temperature difference between the LNG feed and the pipe line gas, a substantial power recovery is suggested.

The thermodynamic Rankine Cycle converts heat into work. The heat is supplied externally to a closed loop with a particular working fluid, and utilizes the LNG as a heat sink. This paper proposes and describes in detail a modified efficient Rankine Cycle using a cryogenic two-phase turbine generator to recover power from the regasification plant.
