−４油中に溶解分散させることができなかった。<Problems to be Solved by the Invention> However, even if the above-mentioned water removal agent is put into a fuel oil storage container, the water removal agent will not be able to reach the tP fuel oil before it comes into contact with the moisture accumulated at the bottom. Because it will dissolve, add m$ of water.
-4 Could not be dissolved and dispersed in oil.
