In Taiwan, huge amount of LNG was imported each year where it was evaporated into NG using sea water to provide for household and facility usage, such as power generation. During this conversion process, tremendous cold energy had been wasted and dissipated to the sea. It is the main goal of this research to reclaim the cold energy for another engineering application to conserve energy.
Research efforts has been focused on Nitrogen Separation process, where pure Nitrogen should be produced in low temperature, and is thus suitable to use LNG cold energy.
It is estimated that among the 20 million kW-h power devoted into N2 separation each year, 48% can be saved from reclaiming LNG cold energy, presenting significant energy-savings potential. Based on 3 processes proposed in this study, the payback years were all ranked within 5 years, indicating promising feasibility for engineering applications.
