A gas treatment system according to one aspect of the present invention comprises: a storage tank for storing carbon dioxide; a reliquefaction device for reliquefying carbon dioxide evaporation gas generated in the storage tank; a loading line that delivers carbon dioxide reliquefied in the reliquefaction device to the storage tank; and a discharging means provided in the loading line and supplying carbon dioxide reliquefied in the reliquefaction device to an offloading line for offloading carbon dioxide in the storage tank to cool down the storage tank, wherein the reliquefaction device can reliquefy carbon dioxide in a range where the pressure of the storage tank is maintained above a lower limit pressure. Thus, the present invention can maintain the temperature and pressure of carbon dioxide at a certain level to prevent dry ice from being generated in a carbon dioxide carrier and clogging pipes.

    본 발명의 일 측면에 따른 가스 처리 시스템은, 이산화탄소를 저장하는 저장탱크; 상기 저장탱크에서 발생된 이산화탄소 증발가스를 재액화시키는 재액화장치; 상기 재액화장치에서 재액화된 이산화탄소를 상기 저장탱크로 전달하는 로딩라인; 및 상기 로딩라인에 구비되어, 상기 저장탱크 내 이산화탄소를 오프로딩하기 위한 오프로딩라인으로 상기 재액화장치에서 재액화된 이산화탄소를 공급하여, 상기 저장탱크를 쿨다운하는 배출수단;을 포함하고, 상기 재액화장치는, 상기 저장탱크의 압력이 하한 압력 이상으로 유지되는 범위에서 이산화탄소를 재액화할 수 있다.
