要約(英語): We investigated and compared the dissolved nitrogen and oxygen gas amounts of mineral oils that had been treated to room air or nitrogen gas replacement, nitrogen fine bubbles (FBs) addition, and nitrogen bubbling addition respectively after degassing treatment. As a result, it was found that most of the nitrogen and oxygen dissolved in mineral oil can be removed according to the degassing treatment used in this experiment. Additionally, it was also found that the nitrogen bubbling addition treatment requires a long time of several hours or more to remove oxygen dissolved in mineral oil, and it is difficult to completely remove the oxygen. Furthermore, it was also found that the nitrogen FBs addition treatment can dissolve a large amount of nitrogen in mineral oil in a short time of than 1/60 compared with the nitrogen bubbling addition treatment.
