Abstract: An apparatus and methodology for storing bitumen froth comprising a fluidized bottom, froth first feed holding tank for maintaining effective tank capacity while reducing overall solid bed build up at side walls and minimizing sloughing of solids to the froth discharge outlet. Froth is fed to the tank through one or more feed inlets located between the froth outlet and side walls for fluidizing settling solids. The feed inlets urge solids to settle in sub-beds about the feed inlets, the height of which that manifests adjacent the side walls being less that some design threshold height; if not, then successive feed inlets are located between the side walls and the precious feed inlets to build further sub-beds that have a height at the wall that is less than the threshold height.

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.
