METHOD OF PROCESSING AND USING HYDROCARBON WASTES Russian patent published in 2003 - IPC

FIELD: utilization of industrial wastes; processing liquid and thickened hydrocarbons for use of them as additive for heavy liquid fuel. SUBSTANCE: proposed method includes heating of hydrocarbon wastes, adding water, mixing hydrocarbon wastes with heavy liquid fuel, dispersion of mixture thus obtained for forming water-and-fuel emulsion and delivery of water-and-fuel emulsion for burning. Hydrocarbon wastes are heated to temperature of 20 to 90 C with or without addition of water. Mixing of hydrocarbon wastes with fuel and dispersion of this mixture are effected simultaneously in rotary pulsating mixer- homogenizer at working clearance of 50-250 mcm and rate of shift no less than 10 m/s, thus ensuring delivery of hydrocarbon wastes and fuel to mixer-homogenizer at ratio of 1:15-1:1.5. Homogenization process is checked by means of measuring microscope or visually by flame jet. When size of particles of dispersion phase in samples of water-and-fuel emulsion is more than 10 mcm or in case of low brightness and transparence of flame or presence of soot in tail portion of flame, speed of motor of mixer-homogenizer shall be increased or part of water-and-fuel emulsion from outlet of mixer-homogenizer shall be fed to its inlet or delivery of fuel to mixer-homogenizer shall be increased or delivery of hydrocarbon wastes to its inlet shall be reduced. EFFECT: possibility of processing hydrocarbon wastes of any class; increased productivity; saving of fuel. 2 cl, 2 ex
