An ammonia gas reliquefaction system of a ship is disclosed. According to an embodiment of the present invention, an ammonia gas reliquefaction system of a ship comprises: a compression unit which receives boil-off gas from a storage tank storing liquefied ammonia and its boil-off gas and compresses it; a cooling unit which cools the compressed boil-off gas; a gas-liquid separator which separates the cooled fluid from gas and liquid; and a pressure control valve provided in a gas discharge line of the gas-liquid separator and whose opening degree is controlled based on the internal pressure of the gas-liquid separator so that the gas-liquid separator is operated at the set pressure.

    선박의 암모니아가스 재액화시스템이 개시된다. 본 발명의 실시 예에 따른 선박의 암모니아가스 재액화시스템은 액화암모니아 및 이의 증발가스를 저장하는 저장탱크로부터 증발가스를 공급받아 압축시키는 압축부; 압축된 증발가스를 냉각시키는 냉각부; 냉각된 유체를 기액 분리시키는 기액분리기; 및 기액분리기의 기체배출라인에 마련되며, 기액분리기가 설정압력에서 운전되도록 기액분리기의 내부 압력을 기초로 개방 정도가 제어되는 압력제어밸브;를 포함한다.
