The present invention relates to a re-gasification device of liquefied natural gas, and more specifically, to a re-gasification device of liquefied natural gas, which can improve the quality of natural gas supplied to a demand by injecting the natural gas in a gas phase into a suction drum instead of nitrogen gas to maintain the constant pressure in the suction drum in which liquefied natural gas is temporarily stored during a re-gasification process of the liquefied natural gas. To this end, the re-gasification device of liquefied natural gas comprises: a storage tank in which liquefied natural gas is stored; a suction drum connected to the storage tank and a first gas feed line to receive the liquefied natural gas from the storage tank; a gasifier connected to the suction drum and a second gas feed line to gasify the liquefied natural gas; a pressurizing pump installed at the second gas feed line to feed the liquefied natural gas from the suction drum to the gasifier; and a pressure maintenance means injecting natural gas obtained after gasifying part of the liquefied natural gas in the suction drum into an upper portion of the suction drum to maintain the pressure of the suction drum.

    본 발명은 액화천연가스의 재기화 장치에 관한 것으로서, 더욱 상세하게는 액화천연가스의 재기화 과정에서 액화천연가스가 일시 저장되는 석션드럼의 내부를 일정한 압력으로 유지하기 위해 질소 가스 대신에 기상의 천연가스를 석션드럼에 주입함으로써 수요처에 공급되는 천연가스의 품질을 높일 수 있는 액화천연가스의 재기화 장치에 관한 것이다. 본 발명의 액화천연가스의 재기화 장치는 액화천연가스가 저장된 저장탱크와, 저장탱크와 제 1가스이송라인과 연결되어 상기 저장탱크로부터 액화천연가스가 유입되는 석션드럼과, 석션드럼과 제 2가스이송라인으로 연결되어 액화천연가스를 기화시키는 기화기와, 제 2가스이송라인에 설치되어 상기 석션드럼으로부터 액화천연가스를 상기 기화기로 이송시키는 가압펌프와, 석션드럼의 압력유지를 위해 상기 석션드럼 내부의 액화천연가스 중 일부를 기화시켜 얻은 천연가스를 상기 석션드럼의 상부로 주입하는 압력유지수단을 구비한다.
