Abstract

PURPOSE: To eliminate oxygen loss by a method wherein an impurity gas such as a carbon dioxide gas or the like in an aeration gas prepared by oxygen aeration is removed and, thereafter, oxygen is replenished in an amount corresponding to the removed gas amount to carry out recirculation aeration to enable constant high concn. oxygen aeration.
CONSTITUTION: A gas containing an impurity gas based on a carbon dioxide gas floated through an aeration cylinder 6 is directly introduced into a gas purifier 24 without sucking the same by an aeration compressor 1 to remove the impurity gas. After this treatment, oxygen is replenished in an amount corresponding to the removed impurity gas amount and the replenished gas is sucked by the aeration compressor 1 to be used in aeration by recirculation. By the impurity gas removal, the gas aerated in the aeration cylinder 6 can keep a high concn. oxygen content near to that of the gas supplied from an oxygen generator 2 and not only oxygen aeration operation can be carried out in good efficiency but also discharge of accompanying oxygen with discharge of the impurity gas is eliminated.
