Utilization of Liquefied Natural Gas Re-gasification Cold Energy in Power Generation Cycles

Abstract

This project studies the comparison between the amount of energy generated from the three common cycles used for power generation, the three cycles used are Direct Expansion cycle, Rankine cycle, and Combined Rankine cycle. The comparison is done using ASPEN HYSYS simulation program to identify which cycle is more reliable. The feed properties for each cycle are identical and so are for all the equipments to make the comparison more realistic. According to this study, it is found that it is possible to make use of the liquefied natural gas cold energy in the power generation which was being wasted.
