Abstract: Embodiments of a feedwell discharge a solvent treated bitumen-containing froth feed to a froth settling vessel at a Richardson number less than 1.0. Feed is discharged from feedwell inlets to the vessel, either located at a center of the vessel or at a perimeter wall of the vessel along a substantially horizontal path across the vessel. The high velocity maximizes the horizontal path. As the velocity is reduced along the path and as a result of collision in the vessel with the perimeter wall or with feed entering the vessel from an opposing inlet, the feed separates into diluted bitumen and solvent which rises in the vessel for discharge as an overflow product and a waste stream, comprising water, solids and asphaltenes, which settles to the bottom of the vessel to be discharged as an underflow. A relatively uniform clarification zone forms above the inlets submerged in the vessel.
