Disclosed is an evaporation gas treating system for a vessel, which uses evaporation gas as a cooling fluid to reliquefy the evaporation gas generated in a liquefied natural gas storage tank installed in a vessel. The evaporation gas treating system for a vessel includes: a compressor compressing the evaporation gas; a heat exchanger heat-exchanging the evaporation gas discharged from the storage tank and the evaporation gas compressed after passing through the compressor; and an expansion unit lowering the pressure of the evaporation gas passing through the heat exchanger and the compressor. The evaporation gas treating system for a vessel returns the evaporation gas, which cannot be reliquefied and stays in a gas state, and the evaporation gas partially reliquefied after passing through the expansion unit to the storage tank.
선박에 설치된 액화천연가스 저장탱크에서 발생하는 증발가스를 재액화하기 위하여 증발가스를 냉각 유체로 사용하는 증발가스 처리 시스템이 개시된다. 상기 선박용 증발가스 처리 시스템은, 증발가스를 압축하는 압축기; 상기 저장탱크로부터 배출된 증발가스와 상기 압축기를 지나 압축된 증발가스를 열교환시키는 열교환기; 및 상기 압축기 및 상기 열교환기를 지난 증발가스의 압력을 낮추는 팽창수단;을 포함하고, 상기 팽창수단을 지나 일부 재액화된 증발가스와 재액화되지 못하고 기체상태로 남아있는 증발가스를 함께 상기 저장탱크로 바로 되돌려보내는 것을 특징으로 한다.
