Definitions
- the present invention is a non-explosive mixed refrigerant used in the reliquefaction apparatus of the fuel supply system for compressing and reliquefying the evaporated gas generated in the liquefied natural gas storage tank to medium pressure, and then compressed and vaporized to a high pressure natural gas injection engine It is about.
- Liquefied gas such as LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas)
- LNG Liquefied Natural Gas
- LPG Liquefied Petroleum Gas
- the liquefied gas is transported in a gas state through a gas pipe on land or sea, or transported to a distant consumer while stored in a liquefied gas carrier in a liquefied state.
- Liquefied gas such as LNG or LPG is obtained by cooling natural gas or petroleum gas to cryogenic temperature (approximately -163 °C in case of LNG), and its volume is greatly reduced than in gas state, so it is very suitable for long distance transportation by sea. .
- Liquefied gas carriers are used to load liquefied gas into the sea and unload this liquefied gas to land requirements.
- a liquefied gas carrier includes a storage tank (commonly referred to as a cargo hold) that can withstand the cryogenic temperature of liquefied gas. do.
- Examples of offshore structures equipped with storage tanks for storing cryogenic liquefied gas are vessels such as LNG RV (Regasification Vessel), LNG Floating Storage and Regasification Unit (FSRU), LNG FPSO (Floating, Production, Structures such as storage and off-loading).
- LNG RV Registered Vessel
- FSRU LNG Floating Storage and Regasification Unit
- LNG FPSO Floating, Production, Structures such as storage and off-loading
- LNG RV is the installation of LNG regasification facilities on liquefied gas carriers that can be self-driving and floating.

- LNG FPSO is a marine structure that is used to directly purify mined natural gas from the sea and liquefy directly to store it in a storage tank, and to transfer LNG stored in the storage tank to an LNG carrier if necessary.
- the offshore structure is a concept including not only vessels such as liquefied gas carriers and LNG RVs but also structures such as LNG FPSO and LNG FSRU.
- the liquefaction temperature of natural gas is about -163 ° C at ambient pressure, so LNG is evaporated even if its temperature is slightly higher than -163 ° C at normal pressure.
- the LNG storage tank of the LNG carrier is insulated, but since the external heat is continuously transmitted to the LNG, LNG is transported while the LNG carrier is transporting the LNG.
- Boil-off gas (BOG) is generated in the LNG storage tank by continuously vaporizing it in the LNG storage tank.
- the generated boil-off gas increases the pressure in the storage tank and accelerates the flow of the liquefied gas in response to the fluctuation of the vessel, it may cause structural problems, so it is necessary to suppress the generation of the boil-off gas.
- the boil-off gas inside the storage tank is discharged to the outside of the storage tank in order to maintain an appropriate pressure in the storage tank and re-liquefied through the re-liquefaction device.
- the boil-off gas is compressed to a low pressure of approximately 4 to 8 bara and fed to the reliquefaction apparatus.
