摘要： Diluent-diluted bitumen froth containing bitumen and naphtha diluent, hydrocarbons, water, sand and fines (collectively “dilfroth”) is fed into a vapor-tight gravity settler (‘splitter’) and temporarily retained to produce a bottom layer of tails comprising sand and middlings, a rag layer of discrete three-dimensional structures, each comprising hydrocarbons contained in a skin of fines, and a top layer of hydrocarbons containing small droplets of water and fines (‘raw dilbit’). The flux in the splitter is less than 6 m3/h of dilfroth fed per m2 of horizontal cross-sectional rag area. The in-coming dilfroth is fed directly into the splitter middlings. Demulsifier is added to the overflow stream of raw dilbit and the mixture is subjected to prolonged settling in a vapor-tight polisher tank, to produce polished dilbit containing less than 1.0 wt. % water and 0.3 wt. % solids. The splitter underflow tails, containing less than 15 wt. % bitumen, is mixed with additional diluent to raise the diluent/bitumen ratio to 4:1 to 10:1 and is gravity settled in a vapor-tight scrubber. Scrubber overflow, mostly diluent containing residual bitumen stripped from the tails, is recycled to the splitter. In concept, the sand is first separated from the bitumen in the stripper. The substantially sand-free bitumen can then feasibly be treated with chemical demulsifier and subjected to prolonged settling in the polisher to reduce water and fines contents to low levels. Bitumen lost with the splitter tails is recovered in the scrubber using a high concentration of diluent. The scrubber overflow of bitumen and diluent is recycled to the stripper to conserve diluent.

摘要： An improved low energy extraction process for recovering bitumen from oil sand whereby essentially all of the thermal energy input for processing the oil sand takes place at the slurry mixing step as opposed to at both the slurry mixing step and the slurry flooding step. Mined oil sand is mixed with sufficient hot slurry water to produce an oil sand slurry having a density in the preferred range of about 1.50 g/cc to about 1.60 g/cc and a temperature in the preferred range of about 40° C. to about 55° C., more preferably greater than about 43° C. The oil sand slurry is conditioned, preferably by pumping it through a pipeline for a sufficient length of time, and then flooded with cold flood water to produce a diluted slurry having a density in the range of about 1.4 g/cc to about 1.5 g/cc and a temperature generally below 40° C. and typically in the range of about 30° C. to about 35° C. The diluted slurry is introduced into a gravity separation vessel where bitumen froth is recovered.

摘要： A large, mechanically agitated pump box is used between a mixer, for mixing oil sand and water to produce a slurry, and a pipeline for conveying the slurry to a processing facility. Prior to the aqueous slurry being discharged into the pump box from the mixer, it is screened to reject large solids. The oversize is directed to an impactor where it is comminuted and the comminuted product is screened again prior to being discharged into the pump box. The pump box is designed to increase the residence time of the slurry in the pump box and to separate the slurry into two phases, the suspended slurry and the larger lumps that cannot be suspended. The larger lumps that settle in the pump box are recycled to the impactor for comminution.

摘要： A large capacity cyclonic separator is used for desanding a conditioned aqueous oil sand slurry comprising aerated bitumen, water and sand to produce pumpable, pipelineable lean froth and sand tailings. The cyclone separator is a vessel which forms an elongated cylindrical separation chamber and has a tangential slurry inlet at one end and, at the opposite end, a peripheral sand removal outlet and a centrally positioned vortex finder. Oil sand slurry is continually tangentially introduced into the cyclone separator to form a rotating vortex, which generates a centrifugal force. The lean froth migrates to the center of the vortex to form an inner core and is removed via the vortex finder. The sand tailings migrate to the outer reaches of the vortex and are co-currently is removed via the sand removal outlet.
