Thermodynamic Analysis of Power Generation Cycle Utilizing LNG

Thermodynamic cycle analysis has been performed for the power generation systems to utilize the cold energy of liquefied natural gas (LNG). Among many possible configurations of the cycle, the open Rankine cycle, the closed Rankine cycle, and the closed Brayton cycle are selecte for the analysis because of their practical importance. The power output per unit mass of LNG has been analytically calculated for various design parameters. The optimal conditions for the parameters to maximize the power output are presented and some of the design considerations are discussed.
