<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing dissolved oxygen in liquid which efficiently remove dissolved oxygen in liquid and perform continuous treatment. <P>SOLUTION: The apparatus for removing dissolved oxygen in liquid includes: a liquid feeding means 4 leading oxygen-containing liquid to a liquid feed pipe 2; a pressurizing part B set in the liquid feed pipe 2; a merging part A merging deoxidation gas at upstream of the pressurizing part B; and a depressurizing part C depressurizing the pressurized liquid at downstream of the pressurizing part B. By merging the deoxidation gas with the liquid at the merging part A to keep the deoxidation gas in the saturated state in the liquid, and depressurizing the liquid in the depressurizing part after pressurizing the liquid, oxygen is removed from the liquid together with the deoxidation gas. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
