FIELD: chemistry.

SUBSTANCE: method for processing a heavy hydrocarbon residue (1) is described, in particular a bitumen residue with an asphaltenes content of 20 to 45 wt % and a content of the material insoluble in tetrahydrofuran in the amount of 10 to 20 wt %, comprising the following steps: heating the processed heavy residue to the temperature of 325-500°C; carrying out a substantially adiabatic expansion of the processed heavy residue in a medium at the pressure equal to or less than 4 kPa abs. (0.04 bar abs.) and the temperature equal to or less than 450°C; for the purpose of separation from the processed heavy residue: the first less volatile fraction (17) having a boiling point at the atmospheric pressure equal to or greater than 540°C, the solid and/or anhydrous residue of which mainly contains asphaltenes and/or other residues insoluble in pentane and insoluble in tetrahydrofuran; the second more volatile fraction (7), mainly containing maltens and other hydrocarbons having a boiling point equal to or less than 540°C at atmospheric pressure.

EFFECT: providing more efficient blowing, the possibility of implementing the method at a very simple installation and without centrifugation.
