Thermodynamic Analysis of an LNG Combined Cycle Power Plant

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.
