METHOD FOR HEAVY OIL FEEDSTOCK PROCESSING Russian patent published in 2017 - IPC C10G15/08 B01J19/08 B01J19/10 C10G7/00 

FIELD: oil and gas industry.

SUBSTANCE: method for cavitation extraction recovery of valuable metals from heavy oil feedstock involves mixing initial feed oil with water and kerosene. The resulting mixture is processed ultrasonically at frequency ranging from 22 to 44 kHz for 5 to 10 minutes. Then, the light fraction is sent for processing, and heavy fraction is mixed with water and chemical extractant. The resulting suspension is processed ultrasonically at frequency ranging from 22 to 44 kHz for 10 to 20 minutes. Heavy fraction is transported to cavitation treatment, where asphaltene fraction associated with the metals is released. The resulting asphaltene fraction is fed to enrichment processing for recovery of metals using traditional enrichment and metallurgical technologies. The light fraction after cavitation treatment contains metalloporphyrins and combines with light fraction after ultrasonic treatment and is sent to the pharmaceutical industry.

EFFECT: increasing yield of light fractions and increasing depth of heavy oil feedstock processing by means of extracting valuable metals.
