FUNGIBLE BITUMEN FROM PARAFFINIC CENTRIFUGATION

摘要

A process for cleaning bitumen froth produced from an oil sands extraction process involves mixing a sufficient amount of paraffinic solvent with the bitumen froth; subjecting the resulting mixture to centrifugal separation in a centrifuge to yield a diluted bitumen product, a water byproduct stream, and a solids byproduct stream; and processing the diluted bitumen product to yield dry fungible bitumen product having a total water/solids content less than about 0.5 wt %, and a recyclable paraffinic diluent stream.
