Beschreibung
Zusammenfassung:	The present invention relates to an improvement on electrostatic settler system in denitrogenation process of raw lubricating oil, which is characterized by adding an adjustable voltage device in electric system to implement quick and effective separation of residue produced after denitrogenation of various lubricating oils and make it more favorable for preparing basic oil of lubricating oil with good oxidation stability.
