PARAFFINIC FROTH PRE-TREATMENT

Disclosed is a process including providing a bitumen froth comprising bitumen, water, and solids. A paraffinic solvent is added to the bitumen froth in an amount below an asphaltene precipitation point to form a diluted bitumen froth. Water is removed from the diluted bitumen froth to form a dewater...

Zusammenfassung:	Disclosed is a process including providing a bitumen froth comprising bitumen, water, and solids. A paraffinic solvent is added to the bitumen froth in an amount below an asphaltene precipitation point to form a diluted bitumen froth. Water is removed from the diluted bitumen froth to form a dewatered diluted bitumen froth. Additional paraffinic solvent is added to the dewatered diluted bitumen froth in an amount above an asphaltene precipitation point for precipitating asphaltene aggregates. The dewatered diluted bitumen froth is separated to form a hydrocarbon-rich stream and a solids-rich stream.
