Disclosed is a method for re-liquefying evaporation gas for a ship. The method for re-liquefying evaporation gas for a ship comprises: 1) a step of compressing evaporation gas discharged from a storage tank; 2) a step of heat exchanging and cooling the evaporation gas compressed in the step 1) by using the evaporation gas discharged from the storage tank as a refrigerant; 3) a step of expanding fluid cooled in the step 2) by an expansion valve; and 4) a step of separating the fluid expanded in the step 3) into a liquefied gas and a gas state evaporation gas by a gas-liquid separating apparatus, wherein an opening degree of the expansion vale is reduced when a flux adjusting valve installed on a line to which the gas state evaporation gas is discharged from the gas-liquid separating apparatus is open 100%, thereby capable of smoothly adjusting internal pressure of the gas-liquid separating apparatus.

    선박용 증발가스 재액화 방법이 개시된다. 상기 선박용 증발가스 재액화 방법은, 1) 저장탱크로부터 배출된 증발가스를 압축시키고, 2) 상기 저장탱크로부터 배출된 증발가스를 냉매로 하여, 상기 1)단계에서 압축된 증발가스를 열교환시켜 냉각시키고, 3) 상기 2)단계에서 냉각된 유체를 팽창밸브에 의해 팽창시키고, 4) 상기 3)단계에서 팽창된 유체를 기액분리기에 의해 액화가스와 기체 상태의 증발가스로 분리시키고, 상기 기액분리기로부터 기체 상태의 증발가스가 배출되는 라인 상에 설치된 유량조절밸브가 100% 열리면, 상기 팽창밸브의 개도를 줄인다.
