METHOD OF PROCESSING OIL WASTES BASED ON OIL SLIME, FUEL OIL OR THEIR MIXTURE WITH PRODUCTION OF WATER-EMULSION FUEL Russian patent published in 2017 - IPC C10L1/32 C08J11/10 

FIELD: oil and gas industry.

SUBSTANCE: method for processing oily wastes based on oil slime, fuel oil or a mixture thereof to produce a water-emulsion fuel includes heating liquid oily wastes, cleaning followed by feeding a purified mixture of hydrocarbons with water for three-stage mixture homogenization in a vibro-cavitation homogenizer along with simultaneous feeding a coal fraction from 15 to 30% of the flow rate of the supplied liquid to produce hydrated fuel with a relative centrifugal acceleration of the rotor of not less than 1200 g and with a gap between the rotor and the stator of not more than 0.25 mm. The method is characterised in that, in the process of the three-stage homogenization of hydrocarbon mixture in the vibro-cavitation homogenizer, the fine powder is uniformly supplied as a coal fraction. The powder is solid waste obtained by thermal processing of rubber and tire wastes during pyrolysis in the absence of oxygen at a temperature of 500-1000°C. Simultaneously, at the first stage of the vibro-cavitation homogenizer, 0.1-2% of magnesium oxide and 0.1-1.0% of low alcohols of the total amount of solid waste are added to the solid waste.

EFFECT: obtaining a stable fuel emulsion, which is used as a boiler fuel, the combustion fuel provides a lower content of carbon monoxide and nitrogen oxides, the method ensures utilisation of pyrolysis waste.
