Disclosed is an ammonia gas reliquefaction system for a ship that can effectively reliquefy ammonia boil-off gas generated in a fuel tank and return it to the fuel tank. According to an embodiment of the present invention, the ammonia gas reliquefaction system for a ship comprises: an absorption tower which produces ammonia water by reacting water with ammonia gas used as a refrigerant; a distillation tower which receives ammonia water from the absorption tower and separates it into water and ammonia gas; and a reliquefaction unit which receives the separated ammonia gas and uses it as a refrigerant, cools the refrigerant using liquid ammonia supplied from a fuel tank, and reliquefies the ammonia gas discharged from the fuel tank through heat exchange with the refrigerant.

    선박의 암모니아가스 재액화시스템이 개시된다. 본 발명의 실시 예에 따른 선박의 암모니아가스 재액화시스템은 냉매로 사용된 암모니아가스에 물을 반응시켜 암모니아수를 생성하는 흡수탑; 흡수탑으로부터 암모니아수를 공급받아 물과 암모니아가스로 분리시키는 증류탑; 및 분리된 암모니아가스를 공급받아 냉매로 사용하되, 냉매를 연료탱크로부터 공급된 액상의 암모니아를 이용하여 냉각시키고, 냉매와의 열교환에 의해 연료탱크로부터 배출된 암모니아가스를 재액화하는 재액화부;를 포함한다.
