Purging Devices For Use In Polymerization Processes

US Patent:
2010024, Sep 23, 2010
Filed:
Mar 17, 2009
Appl. No.:
12/405532
Inventors:

International Classification:
C08F 2/34
B01J 19/00
US Classification:
526 68, 422243
Abstract:
One or more purging devices are provided which prevent buildup of polymer particles on valves used in the production of polyolefins. More particularly, embodiments of the present invention relate to purge devices which direct continuous gas flow onto the face of a ball valve located in a recycle stream to prevent resin buildup. Further embodiments of the present invention relate to polyolefin production processes employing such purging devices.

Dry Product Discharge From A Gas Phase Polymerization Reactor Operating In The Condensing Mode

US Patent:
6472483, Oct 29, 2002
Filed:
Feb 28, 2000
Appl. No.:
09/514167
Inventors:
Mark Gregory Goode - Hurricane WV
Mark Williams Blood - Hurricane WV
Timothy Joseph Howley - Charleston WV
Billy Jack Garner - Charleston WV
Robert Darrell Olson - Charleston WV

International Classification:
C08F 234
US Classification:
526 88, 526 65, 526 70
Abstract:
The liquid content of granular product removed from a fluidized bed polymerization reactor operating in the condensing mode is reduced or minimized by removing the product from a level in the fluidized bed which is about 0. 21 to about 0. 59 of its height while venting the product discharge tank to a point higher in the fluidized bed.
