FUEL BLEND PRODUCTION PROCESS Russian patent published in 2005 - IPC

FIELD: alternate hydrocarbon-based fuels.

SUBSTANCE: object of invention is production both fuel emulsions and fuels in the form of blended different hydrocarbon fractions and wastes containing hydrocarbon components. Process according to invention comprises feeding fuel into apparatus being a body constituted by expanding hollow cone-shaped portion to receive feed and narrowing cone-shaped portion to discharge product, solid angles of cones being 30-120°, and cylindrical portion between cones, wherein perforated plates are disposed perpendicularly to feed stream. Equivalent diameters of perforations decrease in each next plate in downstream direction and distance between adjacent plates is less than equivalent diameter of perforations in upstream plate for each plate pair but larger than that in downstream plate in the same pair. Diameter of feed cone for additional component (D_fc) is found from relationship: D_fc =k·D_c, where k is coefficient determining volume ratio of blended components at k<1 and D_c diameter of cylindrical portion. Advantageously, 2-4 plates are used having angle between perforation axes between 0 and 70°. Dispersing operation is carried out under conditions satisfying relationship: L > πd, where L denotes length of cylindrically stretched drop and d diameter of this stretched drop.

EFFECT: enabled preparation of stable finely-dispersed fuel emulsions.
