<p>Modifying oil is at room temperature mixed with 0.5 to 5.0 wt%. water, after sufficient time is separate from the oil the sludge by centrifugation, then the oil thus prepared add 0.5 to 5.0 wt%. alkanolamine, again mixed for sufficient time and again to add 0.5 to 5.0 wt%. water and continue mixing. After mixing the appropriate time to leave the system in a rest and components eliminated from the oil are removed by centrifugation. Finally, the oil is mixed with 0.5 to 5.0% water and arise precipitate it is centrifuged.</p> |
