METHOD OF ROOFING ASPHALT RECEIVING Russian patent published in 2009 - IPC C10C3/04 

FIELD: oil and gas production.

SUBSTANCE: invention relates to oil processing field, particularly to method of receiving of oxidised roofing asphalt. Invention relates to method of roofing asphalt receiving by means of continuous oxidation of black oil of west Siberian oil at increased temperature in column, in the capacity of black oils it is used compound stock in the form of residue of mazut rectification - tar, and modify-solubilisation admixture, where in the capacity of modify-solubilisation admixture it is used either the second vacuum distillate ABT-2 and ABT-6 with boiling limit 220-260°C at 20-30 millimetres of mercury or residue of total paraffines rectification of manufacturing of linear alkyl benzene in a following ratio: modify-solubilisation admixture10-50%; tar (with penetration 280-350 dmm) - the rest.

EFFECT: proposed method provides receiving of oxidised roofing asphalt with reduced content of resins for the purpose of increasing of its compatibility with polymers and reduction of consumption of the latter at manufacturing of "БПС".
