A liquefied natural gas (LNG) treatment system according to an embodiment of the present invention comprises: a pump which presses the LNG stored in an LNG storage tank and supplies the LNG while changing the pressure or flow rate of the LNG discharged when power is supplied; a first heat exchanger which vaporizes the LNG pressed from the pump to be supplied to a required place; a boil-off gas compressor which receives the boil-off gas generated in the LNG storage tank to press and supply the boil-off gas; and a control part which uniformly maintains the pressure of an inlet end of the required place by controlling the discharge flow rate of the pump, thereby preventing the waste of LNG.

    본 발명의 일 실시예에 따른 액화가스 처리 시스템은, 액화가스 저장탱크에 저장된 액화가스를 가압하며, 전력의 공급에 따라 토출되는 압력 또는 유량을 변화시키며 공급하는 펌프; 상기 펌프로부터 가압된 액화가스를 기화시켜 수요처로 공급하는 제1 열교환기; 상기 액화가스 저장탱크에서 발생된 증발가스를 모두 유입시켜 가압하여 공급하는 증발가스 압축기; 및 상기 펌프의 토출유량만을 제어하여 상기 수요처의 유입단 압력을 일정하게 유지시키는 제어부를 포함하는 것을 특징으로 한다.
