<p>PROBLEM TO BE SOLVED: To suppress the freezing inside a condenser by indirectly exchanging the heat from a gas stream to a refrigerant stream to condense a vapor, further indirectly exchanging the heat from a heated refrigerant stream to a cooled gas stream to form a refrigerant stream, and merging a cryogenic stream with the cooled refrigerant stream to generate the refrigerant stream. SOLUTION: A gas stream is inputted in a device 1 through an inlet 10, the gas stream advances in a stream passage 12 through a condenser 16, and further advances through a heat exchanger 16 for increasing the efficiency. A condensable vapor is removed from the gas stream in the condenser 16, and the cooling potential given to the gas stream in the condenser 16 is recovered by a heat exchanger 18 for increasing the efficiency. The gas stream is discharged from the device 1 through an outlet 20. In a stream passage 14, the gas stream runs through the condenser 22, and the vapor is condensed, and further runs through the beat exchanger 18 for increasing the efficiency to recover the cooling potential. Then, the gas stream is discharged from the device 1 through the outlet 20.</p> |
