TREATMENT OF POOR PROCESSING BITUMEN FROTH USING SUPERCRITICAL FLUID EXTRACTION

摘要

A method for extracting hydrocarbons from a poor processing bitumen froth isprovided comprising subjecting a bitumen, solids and water slurry to flotationin a flotationdevice to produce the poor processing bitumen froth; optionally subjecting thepoor processingbitumen froth to centrifugation to remove a portion of the water from the poorprocessingbitumen froth; and subjecting the poor processing bitumen froth tosupercritical extraction in apressure vessel using a supercritical fluid to produce a hydrocarbon streamsuitable for furtherupgrading.
