The present invention relates to a treatment system of liquefied gas comprising: an evaporative gas supply line connected from a liquefied gas storage tank to a consumer; multiple evaporative gas compressors arranged on the evaporative gas supply line and compressing evaporative gas; and a cooling device for cooling the evaporative gas among the evaporative gas compressors using the cold of liquefied nitrogen. The cooling device includes: a liquefied nitrogen storage tank; and an evaporative gas cooler connected to the liquefied nitrogen storage tank through a liquefied nitrogen supply line and arranged on the evaporative gas supply line for connecting the evaporative gas compressors and the liquefied nitrogen supply line. The treatment system of liquefied gas according to the present invention can improve the compressing efficiency of an evaporative gas compressor or a refrigerant compressor by installing a cooling device capable of cooling evaporative gas or refrigerant among the evaporative gas compressors or among the refrigerant compressors using the cold of liquefied nitrogen.

    본 발명은 액화가스 처리 시스템에 관한 것으로서, 액화가스 저장탱크로부터 수요처까지 연결된 증발가스 공급라인; 상기 증발가스 공급라인 상에 마련되며 증발가스를 압축하는 복수 개의 증발가스 압축기; 및 상기 복수 개의 증발가스 압축기 사이에서 증발가스를 액화질소의 냉열을 이용하여 냉각시키는 냉각장치를 포함하되, 상기 냉각장치는, 액화질소 저장탱크; 및 액화질소 공급라인을 통해 상기 액화질소 저장탱크에 연결되며, 상기 복수 개의 증발가스 압축기 사이를 연결하는 상기 증발가스 공급라인과, 상기 액화질소 공급라인 상에 마련되는 증발가스 냉각기를 포함하는 것을 특징으로 한다. 본 발명에 따른 액화가스 처리 시스템은, 복수 개의 증발가스 압축기 사이 또는 복수 개의 냉매 압축기 사이에서 증발가스 또는 냉매를 액화질소의 냉열을 이용하여 냉각시킬 수 있는 냉각장치를 설치함으로써, 증발가스 압축기 또는 냉매 압축기의 압축 효율을 향상시킬 수 있다.
