This work deals with thermodynamic analysis of an LNG combined cycle power plant with waste heat recovery and utilization system. The LNG combined cycle, consist of gas/steam combined cycle, the subsystems; recover both latent and sensible heat and the other for using the latent heat of water vapor. State f the art in this paper is the use of a condensing heat exchanger as utilization system to gain a higher efficiency and to prevent more losses. Therefore, each component of the cycle is modeled by solving mass and energy equation. Results show the performance of the system increase as a result of installing condensing heat exchanger. The object of this paper is comparing the efficiency of two cycles; with and without utilization system.
