Method For Controlling Fouling In Slurry-Type Polymerization Reactors

View page
US Patent:
7381777, Jun 3, 2008
Filed:
Feb 26, 2007
Appl. No.:
11/711453
Inventors:
Thomas W. Towles - Baton Rouge LA, US
James E. Skinner - Denham Springs LA, US
Robert G. DePierri - Baton Rouge LA, US
James Austin Kendrick - Baton Rouge LA, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C08F 2/12
C08F 10/02
US Classification:
526 59, 526 61, 526 74, 526 84
Abstract:
The present invention relates to methods for controlling fouling in the reaction zone of slurry-type olefin polymerization reactors by measuring a process operating parameter and by responding to said process operating parameter, e. g. , by introducing a gaseous poison for the polymerization catalyst in response to a comparison between said measured parameter and a fouling parameter limit for said measured parameter.

US Patent:
8047228, Nov 1, 2011
Filed:
Feb 23, 2005
Appl. No.:
11/064638
Inventors:
Robert Gail Depierri - Baton Rouge LA, US
Ronald Francis Mire - Port Allen LA, US
John Louis Meng - Baton Rouge LA, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
B29C 47/68
US Classification:
137547, 137550, 25131516, 422131
Abstract:
This invention relates to a valve assembly comprising (a) a valve body defining a valve chamber, an inlet port and a discharge port, wherein the inlet port and discharge port communicate with the valve chamber; and (b) a valve member in the valve chamber, the valve member comprising a passage having (1) a first opening and (2) a second opening housing a filter having an inlet surface proximate to the inlet port and a discharge surface proximate to the discharge port, wherein the passage communicates with the inlet port and discharge port, and wherein the valve member is moveable to alternately juxtapose the inlet port and either the filter inlet surface or the filter discharge surface. The invention further relates to a particulate material metering and/or feed system comprising the valve assembly.

Clog-Resistant Pump Assembly For Slurry Loop Reactor

View page
US Patent:
8124019, Feb 28, 2012
Filed:
Jul 2, 2010
Appl. No.:
12/829590
Inventors:
Robert G. DePierri - Baton Rouge LA, US
Norman F. Cook - Jackson LA, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
F04D 29/54
B01J 19/18
C08F 2/01
US Classification:
422132, 526 64, 415183, 415191, 4151211
Abstract:
The pump assembly includes an impeller rotatably mounted in a pipe of the reactor having blades that generate a flow of fluid slurry through the pipe, a nosecone protruding in an upstream direction in front of the impeller blades that rotates along with the blades, and a plurality of stationary guide vanes connected to the housing upstream of the impeller blades and having free ends that are radially spaced apart from the nosecone. The leading edges of the stationary vanes are shaped to direct any stringy material into the radial gaps between the free ends of the stationary vanes and the rotating nose cone to be shredded and thus prevent fouling and clogging of the pump assembly when such stringy material is generated during the polymerization process.

Continuous Slurry Polymerization Volatile Removal

US Patent:
20020132936, Sep 19, 2002
Filed:
Nov 6, 2001
Appl. No.:
09/992590
Inventors:
James Kendrick - Baton Rouge LA, US
Thomas Towles - Baton Rouge LA, US
Scott Roger - Baton Rouge LA, US
Robert DePierri - Baton Rouge LA, US
International Classification:
C08F002/00
C08F006/10
C08F006/16
US Classification:
526/064000, 422/132000
Abstract:
A process/apparatus is disclosed for continuously separating a liquid medium comprising diluent and unreacted monomers from a polymerization effluent comprising diluent, unreacted monomers and polymer solids, comprising a continuous discharge of the polymerization effluent from a slurry reactor through a discharge valve and transfer conduit into a first intermediate pressure flash tank with a conical bottom defined by substantially straight sides inclined at an angle to that of horizontal equal to or greater than the angle of slide of the slurry/polymer solids and an exit seal chamber of such diameter (d) and length (l) as to maintain a desired volume of concentrated polymer solids/slurry in the exit seal chamber such as to form a pressure seal while continuously discharging a plug flow of concentrated polymer solids/slurry bottom product of the first flash tank from the exit seal chamber through a seal chamber exit reducer with inclined sides defined by substantially straight sides inclined at an angle to that of horizontal equal to or greater than the angle of slide of the polymer solids which remain after removal of about 50 to 100% of the inert diluent therefrom to a second flash tank at a lower pressure.

System And Method For Providing A Continuous Flow Of Catalyst Into A Polyolefin Reactor

View page
US Patent:
20120275931, Nov 1, 2012
Filed:
Dec 22, 2009
Appl. No.:
13/510420
Inventors:
Robert G. Depierri - Baton Rouge LA, US
J. Charles Dabadie - Baton Rouge LA, US
Assignee:
EXXONMOBIL CHEMICAL PATENTS INC. - Baytown TX
International Classification:
B01J 19/00
F04B 53/00
US Classification:
417 53, 422310
Abstract:
Both a catalyst feed system and a method are provided for providing a flow, of a mud-like catalyst slurry into a polyolefin reactor. The system includes a pressurized reservoir of the catalyst having an outlet, and a progressive cavity pump including a stator and a rotor. The pump stator has an inlet connected to the reservoir outlet, and an outlet leading to the polyolefin reactor. In operation, the reservoir is first pressurized to a level a little higher than the pressure of the reactor. The outlet of the reservoir is opened and the progressive cavity pump is actuated. The pressure drop generated across the catalyst slurry contained in the reservoir by the pump causes the slurry diluent to flow between the interstices of the particles of catalyst. The thick, mud-like catalyst slurry is quickly transformed into a much less viscous, syrup-like slurry that flows from the reservoir outlet to the inlet of the pump stator. The progressive cavity pump then continuously conveys the catalyst through the stator outlet and into the reactor.

Rotating Shaft Mechanical Seal

Jul 31, 2017
Appl. No.:
16/323721
Inventors:
- Baytown TX, US
Robert G. Depierri - Baton Rouge LA, US
International Classification:
F16J 15/34
Abstract:
