Abstract
A method for extracting hydrocarbons from a poor processing bitumen froth is provided comprising subjecting a bitumen, solids and water slurry to flotation in a flotation device to produce the poor processing bitumen froth; optionally subjecting the poor processing bitumen froth to centrifugation to remove a portion of the water from the poor processing bitumen froth; and subjecting the poor processing bitumen froth to supercritical extraction in a pressure vessel using a supercritical fluid to produce a hydrocarbon stream suitable for further upgrading.
