PROBLEM TO BE SOLVED: To provide a method for deoxidizing biogas by which a town gas satisfying a prescribed requirement can efficiently be produced from the biogas, which does not require the dilution of the biogas by using a large amount of the town gas (a natural gas) to achieve the oxygen concentration lower than the prescribed standard value required by the town gas, and by which the amount of hydrogen to be added to the biogas can efficiently be regulated, and to provide an apparatus therefor.SOLUTION: There is provided an apparatus for deoxidizing biogas, constituted so that the flow rate measured by a flow meter 11, the oxygen concentration measured by an oximeter 12, the flow rate measured by a flow meter 14 and the oxygen concentration measured by an oximeter 40 may be input to a flow rate controller 15, and a flow rate control valve 16 may be controlled based on these data. |
