Patent number: 7556715Abstract: An inline bitumen froth steam heater system is comprised of steam injection and static mixing devices. The steam heater system heats and de-aerates an input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The inline bitumen froth steam heater is a multistage unit that injects and thoroughly mixes the steam with bitumen resulting in an output bitumen material having a homogenous temperature of about 190° F. The heating system conditions a superheated steam supply to obtain saturated steam at about 300° F. The saturated steam is contacted with a bitumen froth flow and mixed in a static mixer stage. The static mixers provide a surface area and rotating action that allows the injected steam to condense and transfer its heat to the bitumen froth. The mixing action and the increase in temperature of the bitumen froth results in reduction in bitumen viscosity and also allows the release of entrapped air from the bitumen froth.Type: GrantFiled: April 16, 2004Date of Patent: July 7, 2009Assignee: Suncor Energy, Inc.Inventors: Les Gaston, Donald Norman Madge, William Lester Strand, Ian Noble, William Nicholas Garner, Mike Lam

Patent number: 6800116Abstract: Discloses apparatus and method to deaerate and condition bitumen froth obtained from a primary tar sands bitumen extraction process comprising a vessel containing a plurality of inclined plates, called a static deaeration conditioner. The inclined plates of the static deaeration conditioner are substantially equidistantly spaced from each other and are inclined at an angle to the horizontal. The plates form a corresponding plurality of channels there between for the froth to be deaerated to flow along. The declination angle is selected to obtain a gravity induced froth flow rate in the channel that exhibits a lamella effect near laminar flow characteristics, which promotes the creation of a water-enriched froth region near the lower plate of the channel. A braking pump can be provided on an outlet port of the vessel to control the rate of flow through the vessel of the froth to be deaerated and conditioned.Type: GrantFiled: July 18, 2002Date of Patent: October 5, 2004Assignee: Suncor Energy Inc.Inventors: Geoffrey Stewart Stevens, Donald Norman Madge, William Lester Strand
