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. This paper proposes and describes in detail a Modified Brayton Cycle to recover power from the regasification plant.
