  • Patent number: 8685210
    Abstract: An inline bitumen froth steam heater system including steam injection and static mixing devices is provided. The system heats and de-aerates input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The system is a multistage unit that injects and thoroughly mixes steam with bitumen resulting in output bitumen material having temperature of about 190° F. The system conditions a superheated steam supply to obtain saturated steam at about 300° F. The saturated steam is contacted with bitumen froth flow and mixed in a static mixer stage. The static mixers provide surface area and rotating action that allows the injected steam to condense and transfer its heat to the bitumen froth. The mixing action and increase in temperature of the bitumen froth results in reduction in bitumen viscosity and allows the release of entrapped air from the bitumen froth.

  • Patent number: 7726491
    Abstract: An apparatus for processing bitumen froth comprising a cyclone body having an elongated conical inner surface defining a cyclone cavity extending from an upper inlet region with a diameter DC to a lower apex outlet with a diameter DU of not less than about 40 mm; an inlet means forming an inlet channel extending into the upper inlet region of said cyclone cavity; and a vortex finder forming an overflow outlet of a diameter DO extending into the upper inlet region of said cyclone cavity toward said lower apex outlet and having a lower end extending an excursion distance below said inlet channel, said excursion distance being operable to permit a portion of bitumen that passes through said inlet channel to exit said overflow outlet without having to make a spiral journey down said cyclone cavity, wherein a lower end of the vortex finder within the cyclone cavity is disposed a free vortex height (FVH) distance from said lower apex outlet.

  • Patent number: 7556715
    Abstract: 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.

  • Patent number: 7438807
    Abstract: Discloses apparatus to perform a process to remove water and minerals from a bitumen froth output of a oil sands hot water extraction process. A bitumen froth feed stream is diluted with a solvent and supplied to a primary inclined plate separator stage, which separates the bitumen into an overflow stream providing a bitumen product output from the circuit and a bitumen depleted underflow stream. A primary cyclone state, a secondary inclined plate separator stage and a secondary cyclone stage further process the underflow stream to produce a secondary bitumen recovery product stream and a recycle stream. The secondary bitumen recovery product stream is incorporated into and becomes part of the circuit bitumen product output stream. The recycle stream is incorporated into the bitumen froth feed stream for reprocessing by the circuit.

  • Patent number: 6800116
    Abstract: 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.
