A gas treatment system according to one aspect of the present invention is a gas treatment system including a reliquefaction unit for reliquefying cargo. The reliquefaction unit comprises a first reliquefaction unit and a second reliquefaction unit, wherein the first reliquefaction unit cools a first cargo by direct cooling, the second reliquefaction unit cools a second cargo by indirect cooling, the second cargo is carbon dioxide, and the pressure of the carbon dioxide may be at least 0.5 barg greater than a triple point pressure and less than 20 barg. Thus, the present invention can maintain the temperature and pressure of carbon dioxide at a certain level to prevent dry ice from occurring in carbon dioxide carriers and clogging pipes.
