HEAVY OILS WITH IMPROVED QUALITY AND ADDITIVE THERETO Russian patent published in 2002 - IPC

FIELD: lubrication materials. SUBSTANCE: additive consists of oxyalkylated fatty amine or its derivative (1-99%) and metal salt compound, preferably metal soap (1-99%). Heavy oils contain from 2 to 2000 ppm of this additive. Additive gives rise to good emulsification or dispersing of asphaltenes and other high-molecular compounds and therefore to increased storage stability, improved pumping ability due to lowered oil viscosity and to prolonged service life of filter systems. In addition, additive improves combustion of heavy oils. EFFECT: improved working characteristics. 9 cl, 6 ex
