IMPROVED METHOD OF EXTRACTING BITUMEN FROM OIL SANDS Russian patent published in 2018 - IPC C10G1/00 C10G1/04 E21B43/22 C09K8/58 C09K8/68 C10G33/04

Abstract RU 2647582 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a process for recovering bitumen from oil sands. Bitumen recovery process comprises a step of treating oil sands with a glycol ether amine wherein the treatment is intended for oil sands recovered by surface mining or in situ production, wherein the glycol ether amine has the following structural formula: R-(OC₂H₄)_x-NH₂or R-(OCH₂CH(CH₃))_y-NH₂, where R is C₁-C₆ alkyl or phenyl group and x and y are independently 1-3.

EFFECT: technical result is ensuring a significant increase in the extraction of bitumen from oil sands.
