| 20090206040 | SYSTEMS AND METHODS FOR REMOVING FINELY DISPERSED PARTICULATE MATTER FROM A FLUID STREAM - 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. | 08-20-2009 |
| 20090305933 | LOW INTERFACIAL TENSION SURFACTANTS FOR PETROLEUM APPLICATIONS - The invention relates to a class of novel surfactants that have utility in the recovery and/or extraction of oil. | 12-10-2009 |
| 20100252485 | Methods and Apparatus for Removal of Degradation Byproducts and Contaminants From Oil for Use in Preparation of Biodiesel - Methods, particles, and devices are disclosed for filtration of oil for use of the oil in the preparation of biodiesel. Disclosed particles may comprise a substantially inert porous particle with a coating comprising a polymer having amine, amino, and/or imine group(s). | 10-07-2010 |
| 20110065612 | LOW INTERFACIAL TENSION SURFACTANTS FOR PETROLEUM APPLICATIONS - The invention relates to a class of novel surfactants that have utility in the recovery and/or extraction of oil. | 03-17-2011 |
| 20110094970 | SYSTEM, METHODS, PROCESSES AND APPARATUS FOR REMOVING FINELY DISPERSED PARTICULATE MATTER FROM A FLUID STREAM - Disclosed herein are systems and methods for removing fine particulate matter from a fluid, comprising a separator that separates an inflow fluid stream into an overflow fluid path and an underflow fluid path, where the underflow fluid path is treated with a tethering material that attaches to the coarse particulate matter to form tether-bearing anchor particles and where the overflow fluid path is treated with an activating material so that the activating material interacts with the fine particulate matter to form activated particles. After these treatments, the underflow fluid path containing the tether-bearing anchor particles is comingled with the overflow fluid path containing the activated particles, so that a removable complex is produced that can be removed in a settling facility, thereby removing the fine particulate matter from the fluid. The systems and methods are particularly advantageous for removing particulate matter from a fluid waste stream following mining or ore processing operations, such as oil sands mining or processing. | 04-28-2011 |
| 20110100402 | TUNABLE POLYMERIC SURFACTANTS FOR MOBILIZING OIL INTO WATER - The present invention relates to compositions comprising tunable polymeric surfactants and methods for enhanced oil recovery. | 05-05-2011 |
| 20110114539 | SYSTEMS AND METHODS FOR OIL SANDS PROCESSING - 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. | 05-19-2011 |
| 20110120719 | PROPPANTS FOR HYDRAULIC FRACTURING TECHNOLOGIES - The invention is directed to systems and methods for forming and using proppant particles having desirable attributes. | 05-26-2011 |
