Abstract
The invention relates to an improved bitumen recovery process. The process includes adding water to a bitumen-froth/solvent system containing asphaltenes and mineral solids. The addition of water in droplets increases the settling rate of asphaltenes and mineral solids to more effectively treat the bitumen for pipeline transport, further enhancement, refining, or any other application of reduced-solids bitumen.
