Abstract

Disclosed is a gas treatment device that can efficiently regulate the temperature of a gas without being affected by load. Said device is provided with: a compressor (); a heat exchanger; a separator; an expander (); a refrigerant gas flow control valve (); a branching channel (); a first branching-channel heat exchanger () and a second branching-channel heat exchanger (); a first outlet channel that is connected to a liquefied process gas outlet on the separator and that bypasses the first branching-channel heat exchanger (); a second outlet channel that is connected to an outlet on the expander () and that bypasses the second branching-channel heat exchanger (); a first thermometer () in a main channel; a second thermometer () in the branching channel (); a third thermometer () in the separator; a flow control valve () on the main channel; and a control means () that controls the flow control valve () and/or the refrigerant gas flow control valve () on the basis of temperatures measured by the first through third thermometers ().
