LOW-VISCOSITY MAZUT FUEL AND A PROCESS FOR MANUFACTURE THEREOF Russian patent published in 2007 - IPC C10L1/04 B01J19/10 C10L1/32 B01F3/08 

FIELD: petroleum processing.

SUBSTANCE: invention relates to low-viscosity mazut fuel used as process fuel at industrial power-supply enterprises and on river and sea ships. Mazut fuel is composed of mazut M40 and/or M100 (30-60%), stabilized gas condensate wherein C₁-C₄ fraction constitutes not more than 0.3-1.0% (25-50%), and kerosene-gas oil fraction (1-40%). Manufacturing procedure involves preliminarily mixing mazut M40 and/or M100 with stabilized condensate in due proportions. Resulting mix is passed to emulsifying ultrasonic apparatus to form fine emulsion. Alternatively, 1-40% (based on the finished product) of kerosene-gas oil fraction having boiling range 180-350°C is mixed with stabilized condensate at 20-30°C and resulting mix is passed to emulsifying ultrasonic apparatus to form fine emulsion. Mazut preheated to 60°C is added to fine emulsion and the total is additionally treated in ultrasonic apparatus to produce highly homogenized desired product.

EFFECT: increased degree of homogeneity and prolonged storage time of fuel without stratification and with preservation of all required performance characteristics.
