Design of Rankine Cycles for power generation from evaporating LNG

Abstract Of the different ways of using the cold available from the large scale evaporation of LNG the generation of electric power, using the Rankine Cycle, appears the most practical. Fourteen such plants have so far been installed in Japan. The present study was undertaken for a plant at Zeebrugge. Six different cycles using nine different refrigerants and mixtures were examined. The results ( Tables 2 and 3 ) show the importance of using a heat source with the highest possible temperature. No one refrigerant is ideal for all configurations Environmental and safety considerations also affect the choice of refrigerant.
