INTEGRATED PROCESSES FOR RECOVERY OF HYDROCARBON FROM OIL SANDS

摘要

A process for recovering hydrocarbon from oil sands comprises: (a) contacting a first oil sands ore with a solvent to form a solvent-based slurry comprising solids and a bitumen extract; (b) separating the solids from the solvent-based slurry to produce a low solids bitumen extract; (c) removing solvent from the low solids bitumen extract to form a solvent extracted bitumen product; (d) contacting a second oil sands ore with water to form an aqueous slurry; (e) mixing the solvent extracted bitumen product with the aqueous slurry to form a bitumen enriched slurry; and (f) recovering bitumen from the bitumen enriched second slurry.
