  • SYSTEMS, METHODS, PROCESSES AND APPARATUS FOR REMOVING FINELY DISPERSED PARTICULATE MATTER FROM A FLUID STREAM
    Publication number: 20120067824
    Abstract: Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a tailing solution.

  • SYSTEMS AND METHODS FOR OIL SANDS PROCESSING
    Publication number: 20110114539
    Abstract: The systems and methods described herein provide for extracting bitumen from oil sands at ambient or subambient temperature, for example at temperatures between 0 degrees Centigrade and about 20 degrees Centigrade. The process includes the steps of forming a slurry by mixing the oil sands with water, adding an extractant to the slurry, agitating the extractant with the slurry, and collecting bitumen that separates from the slurry.
