The Second-Law Efficiency and Thermoeconomic Analysis of LNG Cold Energy Transmission

Natural gas has been considered a clean energy which is more environmental friendly and with higher combustion efficiency. In Taiwan, most LNG was imported from abroad, with large amount of cold energy for application, despite the fact that it has been utilized for only 8% of total.
In LNG cold energy utilization process, the change of exergy can be simulated with the second law of Thermodynamics as a means to analyze its energy efficiency. Especially, when the transportation distance is long, the optimal insulation thickness can then be calculated to justify its economic feasibility.
In this study, thermoeconomics was applied to analyze the feasibility of LNG cold energy recovery, which warrants it as a powerful design tool in engineering applications.
