The present invention relates to a treatment system for liquefied gas comprising: an evaporation gas supply line connected from a liquefied gas storage tank to a consumer; an evaporation gas compressor arranged on the evaporation gas supply line and compressing evaporation gas; and a sealing device for supplying sealed gas to the liquefied gas storage tank, the evaporation gas compressor or a heat medium pump. The sealing device includes: a liquefied nitrogen storage tank; and a nitrogen circulation sealing part connected to the liquefied nitrogen storage tank through a vaporized gas supply line and formed on the liquefied gas storage tank, the evaporation gas compressor or the heat medium pump. The treatment system for liquefied gas according to the present invention can prevent the liquefied gas stored in the liquefied gas storage tank from leaking to the outside, the evaporation gas in the evaporation gas compressor from leaking toward a drive part or a heat medium in the heat medium pump from leaking toward the drive part since the sealing device, which can utilize vaporized nitrogen generated by vaporizing liquefied nitrogen as the sealed gas of the liquefied gas storage tank, the evaporation gas compressor or the heat medium pump, is installed.

    본 발명은 액화가스 처리 시스템에 관한 것으로서, 액화가스 저장탱크로부터 수요처까지 연결된 증발가스 공급라인; 상기 증발가스 공급라인 상에 마련되며 증발가스를 압축하는 증발가스 압축기; 및 상기 액화가스 저장탱크, 상기 증발가스 압축기, 또는 상기 열매 펌프에 밀봉가스를 공급하는 밀봉장치를 포함하되, 상기 밀봉장치는, 액화질소 저장탱크; 및 기화질소 공급라인을 통해 상기 액화질소 저장탱크에 연결되고, 상기 액화가스 저장탱크, 상기 증발가스 압축기, 또는 상기 열매 펌프에 형성되는 질소순환 밀봉부를 포함하는 것을 특징으로 한다. 본 발명에 따른 액화가스 처리 시스템은, 액화질소를 기화시킨 기화질소를 액화가스 저장탱크, 증발가스 압축기, 또는 열매 펌프의 밀봉가스로 활용할 수 있는 밀봉장치를 설치함으로써, 액화가스 저장탱크에 저장된 액화가스가 외부로 누출되거나, 증발가스 압축기의 증발가스가 구동부 측으로 누출되거나, 또는 열매 펌프의 열매가 구동부 측으로 누출되는 것을 방지할 수 있다.
