PROCESS AND SYSTEM FOR TREATING HEAVY CRUDE OIL AND TAR SAND

A process and system to separate crude from tar sands. A tar sand and crude oil mixture is created using ground tar sands. The tar sand and crude oil mixture is mixed under high pressure in a treatment vessel with either natural gas or exhaust gas from an internal combustion engine. The mixture is then moved through a entrainment vessel still under the high pressure. When the mixture is removed from the entrainment vessel excess gas is removed from the mixture. The crude oil is then separated from the sand typically through a cyclone separator. A portion of the crude oil may be used to mix with the ground tar sand on the front end of the process.

CONDITIONING OF A FEED STREAM FOR A FROTH SEPARATION VESSEL

A bitumen-containing froth is treated with a paraffinic solvent by adding the froth to the solvent in two or more additions prior to separation in a froth settling unit. The first addition of froth results in an S:B ratio which causes precipitation of asphaltenes in the bitumen. Maltenes are dissolved in the solvent. The dissolved maltenes shift the solubility parameter of the solvent. The second or more additions of the balance of the froth to the shifted solvent result in an overall S:B ratio resulting in precipitation of the asphaltenes and dissolving of the maltenes. The volumes of the two or more additions of froth can be adjusted to meet different objectives. Solvent requirements can be reduced, a target asphaltene content in the final product can be altered or both. Further, the target asphaltene content in the product can be designed so as not to foul downstream heating processes.
