Latest Patents

Edward Wing-Kee Chan holds a patent for a froth washer. The washer comprises an open-topped vessel with a vertically mounted tube at its center. Post-primary bitumen froth is fed into the upper end of the tube. Pairs of down throw and up throw propellers are mounted to rotate within the tube, shearing the froth as it descends. The tube is closed off at its lower end by a transverse wall, with slots in the side wall providing an exit for the sheared mixture. This mixture changes direction as it exits the tube. In the vessel chamber, solids and water sink and are removed as tailings through a bottom outlet. The sheared aerated bitumen rises, forming a new froth that is collected in a launder. Middlings are withdrawn from the chamber and recycled to join the feed. The resulting froth has reduced water and solids compared to the feed froth.
