LNG REFUELING SYSTEM AND BOIL-OFF GAS TREATMENT METHOD

Title:

LNG REFUELING SYSTEM AND BOIL-OFF GAS TREATMENT METHOD

Document Type and Number:

WIPO Patent Application WO/2012/118317

Kind Code:

A3

Abstract:

The present invention relates to an LNG refueling system which can deliver LNG to an LNG-fuelled ship and an LNG-refueled ship or can introduce the LNG from an LNG-carrying ship, and more specifically, the invention: separately has a low-temperature LNG tank and a high-temperature LNG tank such that both a low-temperature LNG and a high-temperature LNG can be handled; prevents an increase of pressure in the low-temperature LNG tank, and increases stability; and has a flashing drum such that the high-temperature LNG can be converted into the low-temperature LNG, thereby supplying both high-temperature and low-temperature LNGs. Further, the present invention relates to an LNG refueling system and a boil-off gas treatment method, in which a boil-off gas treatment system is comprised to easily treat the boil-off gas.
