| 20110070367 | Methods of Forming Density-Matched Polymer Slurries - Polymer slurries of ultrahigh molecular weight polyalpha-olefins are made stable toward settling, separation and agglomeration by surface treatment with a combination of wax and optional relatively high-density particulates. The selection of the surface coating acts not only as an anti-blocking agent, or partitioning aid to keep the tacky polymer particles separated, but also provides the suspended polymer particle with a density that matches the carrier. This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating. | 03-24-2011 |
| 20110104371 | RAPID ACTION COATER - A new device and process for continuously applying coatings, such as resin and additives or polymers or the like, to minerals is disclosed. The device and apparatus differ substantially from standard batch coating processes currently used by industry. The apparatus uses a horizontal cylinder with an internal auger and a series of injection ports distributed along the cylinder. Minerals that are to be coated are pretreated and passed through the mixing cylinder using the auger (which may comprise one or more screws with variable pitch blades). As the mineral particles pass through the cylinder various coating materials are injected by the injection ports. The complete system is described, the method of use is explained and the control system which allows for different products is described. | 05-05-2011 |
