Latest Patents

Stovall holds a patent for a device known as the froth washer. This invention comprises an open-topped vessel with a vertically mounted tube at its center. Post-primary bitumen froth is introduced at the upper end of the tube. The device features pairs of down throw and up throw propellers that shear the froth as it descends through the tube. At the lower end, the tube is sealed by a transverse wall, with slots in the side wall allowing for an exit. The sheared mixture changes direction upon leaving the tube. In the vessel chamber, solids and water settle downward and are expelled as tailings through a bottom outlet. The aerated bitumen rises to form a new froth, which is collected in a launder. Middlings are recycled to join the feed, resulting in a product froth that has reduced water and solids compared to the feed froth.
