METHOD OF CLEANING OIL CONTAMINATED WITH WEIGHED PARTICLES IN CENTRIFUGAL SEPARATOR Russian patent published in 2008 - IPC C10G31/10 C10M175/02 

FIELD: physics.

SUBSTANCE: method is used for cleaning oil contaminated with weighed particles using a centrifugal separator. The liquid separation medium, which is denser than the cleaned oil and insoluble in it, is put into a separation chamber in such a quantity that the layer of this medium forms a liquid valve in the rotating centrifugal rotor, covering the output opening for the heavy phase. After this, the oil and the liquid separation medium are put into the separation chamber of the rotating centrifugal rotor. The cleaned oil is output through a central output opening for the light phase of the separation chamber, and the liquid separation medium and the separated particles are output through the output opening for the heavy phase. Heavy polymer is the preferred separation medium.

EFFECT: increased degree of purity of the oil contaminated with hard-to-remove small dispersed particles.
