METHOD FOR CONTINUOUS COMPOUNDING OF OILS Russian patent published in 2020 - IPC B01F5/00 B01F13/08 

FIELD: chemistry.

SUBSTANCE: invention relates to methods for compounding of oils intended for various purposes, for example lubricating oil of friction parts, transformer oils and oils of other purposes. Method comprises mixing base oils with an additive package continuously in a stream of mixture in a vortex layer apparatus at temperature of 18–21 °C. At the same time, impact of cylindrical ferromagnetic bodies located in the working chamber of the vortex layer apparatus is simultaneously performed with the rate of particles position change of 3000–4800 times a minute of each particle, alternating electromagnetic field with frequency of 3000–4800 changes per minute and cavitation occurring under the effect rapidly moving ferromagnetic bodies in oil. Additive package is dispersed in the base oil for 1–3 seconds. Compounding process is carried out continuously, supplying in a vortex layer chamber working chamber a base oil mixture with an additive package at temperature of 18–21 °C, pressure 2 atmosphere, electric current frequency 60–80 Hz and volume flow rate of mixture 30–55 l/min.

EFFECT: technical result is higher viscosity index, low power consumption, continuity of compounding process.
