Title: A single solvent method and machine for separating bitumen from oil sand
Inventor: FLEGAL MICHAEL JAMES
IPC: B03B9/02
Filed: 2013-04-02
Granted: 2017-08-08
Abstract: A single solvent method and machine for separating bitumen from oil sand ore are disclosed. The method includes the use of a single light paraffinic solvent, such as propane or butane as the agent to separate the bitumen from mined oil sand ore. Since light paraffinic solvents are vapors at atmospheric pressure and temperatures, the ore is placed in a pressurized container so that the solvent remains in a liquid state. When the container is pressurized, by the addition of the solvent itself, the liquid solvent is mixed with the ore to effect separation. The proposed machine settles more than 80% of the solids out under gravity in a modest period of time. The solvent - bitumen mixture is drained after the cleaning cycle, the container is depressured to a vapor recovery system and the remaining solids dumped out. The fine solids, drained with the liquids, are separated from the liquid mixture with relative ease by the use of current technology in other downstream equipment.

This method for producing alumina includes: baking of aluminum-containing raw materials; processing of said materials with hydrochloric acid; aluminum chloride salting-out by saturating the clarified chloride solution with gaseous hydrogen chloride; aluminum chloride calcination to produce aluminum oxide, and; mother liquor pyrohydrolysis, including returning hydrogen chloride to the stages of acidic treatment and salting-out. For improving the quality of alumina and reducing power costs, aluminum chloride ¨ precipitated in the course of salting-out ¨ is treated with aqueous ammonia; the resulting precipitate goes to calcination, and the ammonium chloride solution is mixed with said aluminum-containing raw materials before or during baking; ammonia (released during baking) is dissolved in the water; the resulting aqueous ammonia goes to treat aluminum chloride. The ammonium chloride solution ¨ prior to mixing with the aluminum-containing raw materials ¨ may be subjected to stage-wise evaporation (by means of re-using heating steam.) Ammonium chloride (released during evaporation) can be mixed with the aluminum-containing raw materials.
