액화수소 증발가스 재응축 공정의 열역학적 분석

Abstract

This study proposes a re-condensation system aimed at efficiently managing boil-off gas generated in cargo tanks of liquefied hydrogen import terminals. The system’s performance was assessed and validated through thermodynamic analysis, deriving condensation ratios and specific energy consumption (SEC). The sensitivity analysis revealed that as pressure increased from 4.0 to 12.8 bar, the condensation ratio decreased from 24.6 to 7.63, while SEC increased from 0.175 kWh/kg to 0.399 kWh/kg. These results underscore the critical interplay between the condensation rate and SEC in relation to the energy losses and efficiency of the re-condensation system.
