PROCESS FOR TREATING CONTAMINATED TRANSFORMER OIL Abstract of the Disclosure A process for treating contaminated transformer oil which comprises heating the contaminated transformer oil in a first heater to a temperature in the range of 100 to 125°F, passing the heated contaminated oil from the first heater through an adsorber containing Fuller's earth of about 30 to 60 mesh particle size, conducting the treated oil from the adsorber to a chiller where the temperature is reduced to about 50 to 70°F, conducting the treated oil from the chiller to a centrifuge to remove free water, conducting the treated oil from the centrifuge to a second heater where the oil is heated to a temperature of about 100 to 160°F (preferably about 120°F.),conducting the treated oil from the second heater to a degasifier wherein the oil is subjected to a vacuum of about 0.2 to 2 mm of mercury, removing the treated oil from the degasifier and passing it through a polishing filter.
