Boil-off gas (BOG) in an LNG (Liquefied Natural Gas) carrier is inevitably formed because of the heat transfer between the environment and the LNG whose temperature is 113 K. BOG re-liquefaction facility on the LNG carrier is becoming an essential component to manage the BOG. Since BOG contains high concentration of nitrogen, the BOG re-liquefaction cycle requires higher specific work consumption compared to that of natural gas liquefaction cycle. A more efficient BOG re-liquefaction cycle, therefore, draws great attention in the LNG industry. In this paper, BOG re-liquefaction cycle which is based on a Dual Mixed Refrigerant (DMR) cycle is considered to achieve high re-liquefaction efficiency. Low BOG pressure (1400 kPa) condition, high BOG pressure (6000 kPa) condition, flammable mixed refrigerant (FMR) and non-flammable mixed refrigerant (NF-MR) cases are analyzed to identify the performance improvement factor for high efficiency. The physical condition of high BOG pressure presents lower specific work consumption compared to that of low BOG pressure condition. This paper discusses the thermodynamic background for such a result.
