The present invention relates to a boil-off gas liquefaction system and a ship, which comprises: a liquefied gas storage tank provided on a ship and storing liquefied gas; a boil-off gas compressor for compressing boil-off gas discharged from the liquefied gas storage tank and supplying the compressed boil-off gas to a demand; a liquefaction unit for liquefying the surplus that is not consumed in the demand among the compressed boil-off gas; a gas-liquid separator for separating the liquefied boil-off gas into a gas phase and a liquid phase; and a cooling unit for cooling the boil-off gas between the liquefaction unit and the boil-off gas compressor The cooling unit circulates the vapor phase boil-off gas separated in the gas-liquid separator to cool the boil-off gas. The gas-liquid separator is, depending on whether the demand is operated, to deliver the vapor phase boil-off gas to the cooling unit or to the boil-off gas compressor.

    본 발명은 증발가스 액화 시스템 및 선박에 대한 것으로서, 선박에 마련되며 액화가스를 저장하는 액화가스 저장탱크; 상기 액화가스 저장탱크에서 배출되는 증발가스를 압축하여 수요처에 공급하는 증발가스 압축기; 압축된 증발가스 중 상기 수요처에서 소비되지 않은 잉여분을 액화하는 액화부; 액화된 증발가스를 기상과 액상으로 분리하는 기액분리기; 및 상기 액화부와 상기 증발가스 압축기 사이에서 증발가스를 냉각하는 냉각부;를 포함하며, 상기 냉각부는, 상기 기액분리기에서 분리된 기상증발가스를 순환시켜 증발가스를 냉각하며, 상기 기액분리기는, 상기 수요처의 가동 여부에 따라, 기상증발가스를 상기 냉각부로 전달하거나 상기 증발가스 압축기로 전달하는 것을 특징으로 한다.
