PROCESSING OF ASPHALTENE-CONTAINING TAILS Russian patent published in 2010 - IPC B03D1/02 B03B9/06 

FIELD: process engineering.

SUBSTANCE: invention relates to production of materials from asphaltene-containing tails obtained in processing of oil-bearing sands. Proposed method comprises introducing gas into asphaltene-containing tails, extracting heavy mineral concentrate and light tails containing water asphaltene from foam enriched in asphaltene or suspension enriched in asphaltene formed from foam enriched in asphaltene, dispersing substances for hydrophobic agglomeration inside light tails for drop formation and extraction of asphaltene-containing tails from light tails representing asphaltene concentrate. Method of producing materials dispersing substances for hydrophobic agglomeration inside light tails for drop formation and extraction of asphaltene-containing tails from light tails representing asphaltene concentrate. Method of extracting asphaltene from other hydrocarbons comprises producing bitumen foam containing bitumen, asphaltenes, inorganic sold substances and water, producing mix of bitumen foam and paraffin hydrocarbon solvent, diving said mix into diluted bitumen product and residue, producing over 0% to about 95% of paraffin hydrocarbon solvent present in said residue, in aggregate for solvent extraction and extraction of settled asphaltenes and non-extracted paraffin hydrocarbon solvent from the flow of tails. System to produce materials from asphaltene-containing tails comprises floatation apparatus for dividing said tails into foam enriched in asphaltenes and asphaltene-depleted water phase, gravity separation apparatus to separate foam enriched in asphaltenes or suspension enriched in asphaltenes, and mixer for hydrophobic agglomeration for dispersion of substance for hydrophobic agglomeration in the volume of light tails. System for processing asphaltene-containing tails comprises appliances for extraction of asphaltene concentrate from asphaltene-containing tails and appliances to extract oxygen-containing mineral concentrate from asphaltene-containing tails.

EFFECT: higher efficiency of processing.
