Abstract: Method for replacing a coolant containing PCB in electrical induction apparatus having a tank containing the PCB-containing coolant and an electrical winding and porous solid cellulosic electrical insulation immersed in the PCB-containing coolant with a substantially PCB-free permanent coolant to convert said electrical apparatus into one in which the rate of elution of PCB into the PCB-free coolant is below the maximum allowable rate of elution into the coolant of an electrical apparatus rated as non-PCB, the porous electrical insulation being impregnated with said PCB-containing coolant. The method comprises the steps of: (a) draining the PCB-containing coolant from said tank to remove a major portion of the PCB-containing coolant contained by it; (b) filling the tank with an interim dielectric cooling liquid that is (1) miscible with PCB, (ii) sufficiently low in viscosity to circulate within said tank and penetrate the interstices of the porous solid electrical insulation, and (iii) capable of being readily separated from said PCB; (c) electrically operating the electrical induction apparatus for a period sufficient to elute PCB contained in the PCB-containing coolant impregnated in the porous insulation therefrom into the interim dielectric cooling liquid; (d) thereafter draining the interim dielectric cooling liquid containing the eluted PCB from the tank; (e) repeating the cylce of steps (b), (c) and (d), when the rate of elution of PCB into the interim dielectric cooling liquid exceeds 0,55 ppm of PCB per day based on the weight of the permanent dielectric coolant, a sufficient number of times until the rate of elution of PCB into the interim dielectric cooling liquid does not exceed the rate of 50 ppm PCB based on the weight of the permanent coolant after 90 days of electrical operation; and (f) filling the tank with a substantially PCB-free permanent coolant selected from the group consisting of high boiling, high viscosity, silicone oils, synthetic ester fluids, poly-alpha-olefin oils and hydrocarbon oils.

Abstract: A process and device are disclosed for cleaning in particular PCB-contaminated electric appliances (10) such as transformers filled with a fluid. The device has a fluid circuit (14), a distillator (34) for cleaning the fluid, a mixer (22), in which a headstream coming from the distillator is mixed with the fluid circulating in the circuit and flowing back to the electric device, and a feed pump (26). In order to achieve a reliable decontamination or reclassification with a device having a compact design, the fluid to be cleaned is supplied to the distillator (34) at or almost at the bottom of an evaporator (68), flows in the evaporator through an outer annular space and an inner space separated therefrom, and is heated and at least partially evaporated in the annular space.

Abstract: A method for recovering base oil from waste lubricating oil by separating base oil range constituents from a waste lubricating oil mixture, thereafter separating higher quality base oil constituents and lower quality base oil constituents from the base oil recovered from the waste lubricating oil mixture and thereafter treating the lower quality base oil constituents to produce marketable base oil. The total base oil produced from a waste lubricating oil mixture by this process is greater than the quantity producible by previous processes using only base oil separation from the waste lubricating oil mixture or processes which use only treatment of the base oil recovered from the waste lubricating oil mixture to produce the product base oil.

Abstract: Non-ionic pollutants are removed from the soil by contacting the soil with a mixture of a particulate material having an anionic surfactant absorbed to a magnetic oxide. The surfactant complexes through the anionic charge to the magnetic particle and the non-ionic pollutants partitions into the sorbed surfactant. The particulate material including the surfactant and pollutant are magnetically removed from the soil. A typical embodiment utilizes ferric ferrous oxide and alkyl lauryl polyoxycarboxylate to remove polychlorinated biphenyls from soil.
