| 20100133152 | STREAMER TRAP ASSEMBLY - A streamer trap assembly for collecting streamers from a flow of polymer pellets includes a housing comprising an inlet, an outlet, and an opening bounded by a sealing surface; and a streamer trap positioned in the housing through the opening. The streamer trap comprises a screen sized to collect the streamers at the screen and to allow the polymer pellets to pass through the screen, a guide positioned to guide the flow of polymer pellets from the inlet to the screen and from the screen to the outlet, and a cover adapted to engage the sealing surface and cover the opening. | 06-03-2010 |
| 20090215956 | METHOD OF PREVENTING OR REDUCING POLYMER AGGLOMERATION ON GRID IN FLUIDIZED-BED REACTORS - A process for preventing or reducing polymer agglomeration and/or accumulation on or around the gas distribution grid in an olefin polymerization, fluidized-bed reactor. The process involves introducing one or more scouring balls into the reactor above the gas distribution grid, and carrying out olefin polymerization in the presence of the scouring balls. Also disclosed is a process for polymerizing olefins in a fluidized-bed reactor with reduced polymer agglomeration and/or accumulation on the gas distribution grid. | 08-27-2009 |
| 20090211597 | METHOD OF PREVENTING OR REDUCING AGGLOMERATION ON GRID IN FLUIDIZED-BED VESSEL - A method for preventing or reducing agglomeration and/or accumulation on or around the gas distribution grid in a fluidized-bed vessel. The method involves introducing one or more scouring balls into the vessel above the gas distribution grid, and carrying out a fluidized-bed process in the presence of the scouring balls. | 08-27-2009 |
