Dear Sirs....The enclosed patent application, relates to the extraction of bitumen from tar-sands. Alberta tar-sands are a vast energy source in the early stages of development! billions of dollars have already been spent in development capitol.
Suncor, AND Syncrude have pioneered the early development of our tar-sands and now supply 15-20 % of Candies oil requirements.
However $ 125,000,000.00 spent by 6 major oil companies and the Albert, Sakatchewan and Federal governments, have ( with the most up to date technology) failed to put together an new development that is economically viable at present world prices;
the consortium have delayed or abandoned their project. The failure of this major effort is indicative of the need for new technology if our vast tar-sands are to contribute further to Canada,s oil requirements. As conventional oil reserves diminish the need for tar-sands development becomes more pressing.
Hundreds of acres of land have been diked to contain the sludge inherent with the Suncor and Syncrude processing systems, the ponds are environmental tolerated waiting new technology that so far has not been forth coming.
It is therefor an object of this invention to present very simplified equipment, arranged in a different setting, which will greatly reduce equipment costs and operating efficiency.
The equipment and its arrangement has inherent within itself a continuous recycling of all water required in the bitumen extraction process, thus eliminating the environmentally undesirable slud~e ponds associated with the Suncor and Syncrude Systems.
After removal of the over-burden Suncor has used Krupp manufactured bucket wheels for tar-sands mining, while Syncrude has used mainly drag-lines in their mining operation; these machines are very large, cumbersome expensive to buy, and because of their complex nature require extensive and expensive repair.
The severe winters in the north compounds the problems with these massive machines, whose components can at best be only partially shielded from the cold.
In contrast to the present systems of mining, then stock piling and processing at a remote extraction plant,(where bitumen is recovered, and the tailings are sent to a tailings pond): the 6 drawings herein contained, identify a method whereby, mining, bitumen recovery and tailings disposal are combined into a single mobile operation, where each operation compliments the other.
Older ones recall when grain harvesting consisted of cutting, binding grain into sheaves, stooking the sheaves, then hauling the sheaves with wagon racks to a central threshing machine.
The modern combine is the outcome of joining these operations into one, which cuts and threshes in a single mobile operation.
The object of this patent is an effort to combine tar-sands mining and bitumen extraction into a single operation mirrorrng that of the combine for grain harvesting. We believe similar reductions in cost waits to be achieved in mobile oil-sands harvesting as was achieved by changing to t~1e mobile combinë
for grain harvesting.
20~2121 I will first identify the 6 drawings, then describe in detail the drawing and its function witllin the system!
FIG 1....(~) is a schematic elevation end view of the forward moving components. (B) is a schematic plan vlew (floor plan~
of the components which form the system.
FIG 2.......... are elevation, side and end views of the bitumen extraction plant mounted within the mobile enclosure.
FIG 3....... is a proposal for separating the circulatior~ water form the already depleted sands.
FIG 4.... is a schematic elevation view of a proposed system for separating clay fines from the circulation water.
FIG 5.... shows the bucket excavator conveyor ( B.E.C.) and the carriage to which it is anchored and motivated.
FIG 6 .... shows a bucket wheel, which might be preferred to the use of the Bucket excavator conveyor (B.E.C.).
FIG 1 (A) This drawing shows the Bucket Excavator Conveyor (B.E.C.) suspended and motivated by a suspension beam with wheels on rails (front) and rails on top of wheels at the rear of the suspension beam. A cable'land winch~ anchored to the suspension beam will raise and lower the front~of the B.E.C. as required for most effective excavation of the tar-sands: The processing enclosure is carried on carrier tracks at the rear and by powered carrier tracks at the front which motivate the oil harvester forward, and if required backwards. Extraction plant FIG 2 will be placed directly over the un-powered carrier tracks near the rear of the processing enclosure. Fines and circulation water separator FIG 4 may be placed in the processing enclosure, or it may be mounted on wheels and be towed at the rear of the process enclosure (P.E.). Sand and water separator FIG 3 will be towed behind the P.E. Steam generators as required will be mounted on wheels and be towed behind the P.E.
FIG 1 (B) is a schematic floor plan showing the various components and extrapolates there locations.
FIG 2....is a method for extracting bitumen from tar-sands designed to operate within a mobile tar-sands mining and bitumen extraction enclosure (FIG 1).
The bucket excaVatorS mine tar-sands directing them by conveyer into a rotary screen A (4" mesh?) here rejects are screened out and high pressure water jets reduce the tar-sands which drop downward unto screen B (-" mesh?), here rejects are screened and tar-sands reduced to less than ~" by water jets. The reduced tar-sands drop downwards unto rubber faced rollers (RR) which squeeze the bitumen upward and the sands downward, the rollers may be placed above or below the vat water level: as the sands fall downward for extrusion by augur (SE) water jets 8 create an up-flow in the vat carrying the released bitumen upward for recovery at the vat surface; impeller B1 assists in bitumen flow out of the vat for processing at an up-grader ~he fines with the circulation water drop through airation 5; airation is designed to float tlle bitumen contaitled in the fines at~
return water upward for recovery and discharge from the vat:
the circulation water with fines pass through metering valve 6 and are directed to FIG 4 for separation and extrusion of fines and recovery of clarified water: the depleted sands drop downward and are directed to sands and circulation water separator FIG 3 by extrusion augur (SE). Should the rubber faced roller prove unsai-isfactory for fin~l redllc~iol~ or t~ r-.s.~
the extrusion augur would be made longer to do tl1e job proposed by the rollers, the bitumen would then be recovered with the circulation water of FIG 3. Metering valve 6 maintains a const~nt water level in the vat.
FIG 3.... fig 3 is a method for recovering the circulation water from the sand tailings: rotating sand buckets with screen bottoms will lift the sand out of the water and deposit it on a conveyer belt for discharge to an adjacent tailings disposal field.
FIG 4.... is a suggested method to clarify and separate the circulation water from midlings (fines, mud) contained therein.
An appropriate polymer is added to the effluent, which is injected with air into a mixing chamber 1, air assists in the flotation of bitumen residue to the surface of chamber 2 for recovery with the circulation water: the polymer floculates the Midlings (fines, clays ) which migrate downward in vat 2, compaction blades 3 turning slowly press the fines downward into extrusion augur 4 for discharge unto tailings disposal belt SJ The circulation water is recovered for re-injection over the reject screens of fig 2.
FIG 5....is a schematic drawing of the bucket excavator conveyer (B.E.C.); this drawing is shown separated from the carriage for clearer identification: suckets 3 are hinged together and revolve around upper wheel 1 and excavator wheel 2, an appropriate frame works align and hold in place idler wheel 2 and drive wheel 1; the B.E.C. is anchored to the carriage at 1: Carriage 5 mounted on rails and wheels is designed to motivate the B.E.C across the width of the designed excavation providing T-S feed. Carriage 5 rolls on wheels and rails 6 and 13, 13 has the rails above the wheels: winch 9 and cable 12 operating over cable wheel 11 motivate the up and down front movement of the B.E.C. (2), No 7 is the main beam that carries the weight of the B.E.C, the carriage~and the front end of the processing enclosure, it transfers that weight unto the powered tracks 8; the ~owered tracks motivate the entire operation forward~ and backward if required. Conveyors C anchored to the frame of the process enclosure transfer the tar-sands feed from the B.E.C to the bitumen extraction plant 2. A third wheel 10 may be incorporated in the excavation system to improve clean up .
FIG 6... would have the same carriage as FIG 5, but instead of the B.E.C, it would use buckets anchored to a wheel; in this case hydraulic cylinders would move the excavation wheel slightly up and down to accommodate excavation.
