PROBLEM TO BE SOLVED: To provide a method to efficiently recover carbon dioxide gas generated in beer brew. SOLUTION: A dehumidifying device 7 and a deodorizing device 8 in a gas refining system are respectively constituted of adsorption tube pairs 7a, 7b and 8a, 8b for regeneration. Adsorption tubes in each device are alternately used in an adsorption process and a regenerating process. A supply path 13 for gas regeneration branched from a refined gas discharge path 12 is communicated with each outlet side of the dehumidifying device 7 and the deodorizing device 8. Regenerating gas take-out paths 16, 17 guided out from each inlet side of the dehumidifying device 7 and the deodorizing device 8 are individually communicated with a material gas supply path 1. A regenerating gas take-out path 17 is branched to form an atmospheric escape path. Heated regenerated gas is flowed in the dehumidifying device 7 before the dehumidifying device 7 is regenerated by non-heated regenerated gas. Steam is flowed in the deodorizing device 8 for regeneration before heated and non-heated regenerated gas are flowed. Regenerated used gas is returned from the dehumidifying device 7 to the material gas supply path 1. Heated and non-heated regenerated gas are returned to the material gas supply path 1. |
