Title: Method for extracting bitumen from tar sands
Inventor: DAVIS ROBERT MICHAEL
IPC: B03B9/02
Filed: 1996-06-26
Granted: 2008-02-26
Abstract: A method for extracting bitumen from crushed mined tar sands comprising contacting the mined tar sands with a solvent in the presence of sonic energy in the frequency range of 0.5 to 2.0 kHz. Specifically, a solvent is first mixed with crushed mined tar sands and the mixture is then formed into a slurry of tar sand suspended in the solvent. Thereafter the tar sand slurry is injected into the top of a vertically disposed, substantially rectangular shaped, hollow acoustic chamber of uniform cross-section. Fresh solvent is injected into the bottom of the acoustic chamber and flows upwardly through the cell. The fresh solvent is injected into the bottom of the acoustic chamber at a rate low enough whereby the tar sand particles in the slurry fall by gravity through the upwardly flowing solvent. The tar sand particles and solvent in the acoustic chamber are subjected to acoustic energy in the frequency range of 0.5 to 2.0 kHz whereby the bitumen is separated from the tar sand and dissolved by the upwardly flowing solvent without cavitation of the solvent. The bitumen dissolved in the solvent is recovered from the top of the acoustic chamber and transferred by pipeline to an off-site refinery. The bitumen-extracted sand particles recovered from the bottom of the acoustic chamber may be recycled to the top of the acoustic chamber to recover additional bitumen after injection of the slurry has been discontinued.

A  preferred alkoxyphenol is vanillin, and the minerals are selected from the group consisting of Mg, Ca, Cr, Mn, Fe, Co, Cu, Zn, Mo and Se. Vanillin metal chelates have a slight to neutral taste, and are absorbed more readily than inorganic mineral salts.
