A PROCESS FOR THE REGENERATION OF LUBRICATING OILS AND A PLANT FOR REALIZING THE SAME

A process for the regeneration of lubricating oilscomprises withdrawal of mechanical admixtures by afiltration method, treatment with aqueous solutioncontaining hydroxyl groups in the conditions of a preheating to 140-160 DEGREE c, withdrawal of low-boiling particle by a rectification method, distillation in vacuum with distribution into lubricating oils and the rest. To heat the oil an induction method with an intensive mixing thereof with element heated by high frequency currents is used. A plant for regeneration of lubricating oils contains unit for vacuum filtration of used oils, reservoir for used oils, heat exchanger of preheating oil connected by the pipeline for delivery of hot water and pipeline for delivery of used oil through the pump with vacuum-distillation column having disk-shaped nozzles which are connected by pipelines to the unit for withdrawal of water and light fractions and unit of purified oil. The column is provided with revolving rotor with blades, to said column a high frequency currents generator is connected though the inductor.
