METHOD OF RECYCLING OF LIQUID OILY WASTES WITH PRODUCTION OF WATER-EMULSION FUEL Russian patent published in 2015 - IPC C10L1/32 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the recycling method of the liquid oily wastes with of the water-emulsion fuel, it includes heating of the liquid oily wastes, cleaning with further delivery of the cleaned mixture of the hydrocarbons with water for three times homogenization of the mixture. The cleaned mixture is supplied to the vibration and cavitation homogenizer, simultaneously to the said homogenizer the coal fraction is supplied in amount of 5-10% of flowrate of the supplied liquid mixture during each passage through the homogenizer until content of the coal fraction to 15-30% of hydrated fuel. The cleaned mixture of the hydrocarbons with water and with coal fraction is treated in the vibration and cavitation homogenizer at relative centrifugal acceleration of the rotor at least 1200 g, and clearance between the stator and rotor 0.25 mm, ensuring dispersion in film with maximum thickness 0.25 mm.

EFFECT: increased stability of the emulsion.
