  • APPARATUS AND METHOD FOR BITUMEN FROTH STORAGE
    Publication number: 20150275095
    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.
