The present invention relates to a liquefied gas treatment system comprising: a liquefied gas supply line connected from a liquefied gas storage tank to a consumer; and an evaporative gas re-liquefying part arranged on an evaporative gas liquefying line for re-liquefying evaporative gas, which has been generated in the liquefied gas storage tank, and including an evaporative gas condenser, wherein the evaporative gas re-liquefying part re-liquefies the evaporative gas using the cold of refrigerant in the evaporative gas condenser and the cold of liquefied gas. The liquefied gas treatment system according to the present invention can improve the liquefying efficiency of the evaporative gas re-liquefying part by cooling the evaporative gas using the cold of the liquefied gas, which flows through the liquefied gas supply line, together with the cold of the refrigerant, which flows through a refrigerant circulating line. Also, a load on a liquefied gas vaporizer can be reduced by raising the temperature of the liquefied gas supplied to the liquefied gas vaporizer using the heat of the evaporative gas, which is liquefied in the evaporative gas re-liquefying part.

    본 발명은 액화가스 처리 시스템에 관한 것으로서, 액화가스 저장탱크로부터 수요처까지 연결된 액화가스 공급라인; 및 상기 액화가스 저장탱크에서 발생한 증발가스를 재액화시는 증발가스 액화라인 상에 마련되며, 증발가스 응축기를 포함하는 증발가스 재액화부를 포함하되, 상기 증발가스 재액화부는, 상기 증발가스 응축기에서 냉매의 냉열과 상기 액화가스의 냉열을 활용하여 상기 증발가스를 재액화시키는 것을 특징으로 한다. 본 발명에 따른 액화가스 처리 시스템은, 냉매 순환라인을 유동하는 냉매의 냉열과 함께 액화가스 공급라인을 유동하는 액화가스의 냉열을 활용하여, 증발가스 응축기에서 증발가스를 냉각시킴으로써, 증발가스 재액화부의 액화 효율을 향상시킬 수 있고, 또한, 액화가스 기화기로 공급되는 액화가스를 증발가스 재액화부에서 액화되는 증발가스의 온열을 활용하여 온도를 상승시킴으로써, 액화가스 기화기의 부하를 절감할 수 있다.
