Development of bog liquefaction system utilizing cold energy storage; developpement d'un systeme de liquefaction du gaz perdu par evaporation (bog) utilisant le stockage de l'energie frigorifique

摘要

Osaka Gas Co.. Ltd. and Kobe Steel. Ltd. have jointly developed a boil-off gas (BOG)liquefaction system using cold energy storage (CES). This highly efficient system for processing BOG generated from LNG tanks features the application of CES that can store LNG cold energy. CES enables stable liquefaction of BOG even at night when a shortage of LNG cold energy for BOG liquefaction occurs, and this system requires 40 approx 50 percent less power for BOG processing than conventional processing method.
