Abstract
The invention is directed to a process for separating bitumen froth into an upper bitumen-rich, reduced-solids layer, and a lower concentrated solids layer using a cone-bottomed, raked froth tank. The process involves introducing bitumen froth into the froth tank; rotating at least one movable picket through the bitumen froth; recovering the upper bitumen-rich, reduced-solids layer; and withdrawing the lower concentrated solids layer from the tank.
