LNG LNG LNG LNG BOIL-OFF RE-LIQUEFACTION SYSTEM FOR SMALL AND MEDIUM LNG FUEL PROPULSION SHIPS AND METHOD TO RE-LIQUEFACTION LNG BOIL-OFF USING THEREFORE

摘要

The present invention re-liquefies boil-off gas (BOG) generated from LNG fuel, which is emerging as a clean fuel, through a number of heat exchangers multiple times, so that BOG thrown away even in small and medium-sized vessels that are not equipped with a separate re-liquefaction system can be effectively recycled. Of course, it relates to an LNG boil-off gas reliquefaction system for a small and medium-sized LNG fuel propulsion ship, and a method for reliquefying an LNG boil-off gas using the same, which reduces the operation cost and bunkering cost of small and medium-sized ships.
