Process For The Production Of Styrene Monomer By Improving Energy Efficiency And Injecting A Recycle Gas Into The Eb Vaporizer
US Patent:
7910784, Mar 22, 2011
Filed:
Jun 14, 2008
Appl. No.:
12/139456
Inventors:
Kevin J. Schwint - Long Valley NJ, US
Richard J. Wilcox - West Caldwell NJ, US
Richard J. Wilcox - West Caldwell NJ, US
Assignee:
Lummus Technology Inc. - Bloomfield NJ
International Classification:
C07C 5/327
US Classification:
585444, 585443, 585440
Abstract:
This invention relates to a process for the production of styrene monomer by the dehydrogenation or oxidative dehydrogenation of ethylbenzene in the presence of recycle gas and more particularly to a method of reducing the boiling point of liquid ethylbenzene feed in the production of styrene monomer. The process comprises the step of catalytically dehydrogenating or oxydehydrogenating ethylbenzene in the presence of a mixture, wherein the mixture substantially comprises carbon dioxide, thereby catalytically producing styrene monomer.
Styrene Monomer Process Based On Oxidative Dehydrogenation Of Ethylbenzene Using Coas A Soft Oxidant
US Patent:
7964765, Jun 21, 2011
Filed:
Jun 14, 2008
Appl. No.:
12/139455
Inventors:
Kevin J. Schwint - Long Valley NJ, US
Richard J. Wilcox - West Caldwell NJ, US
Richard J. Wilcox - West Caldwell NJ, US
Assignee:
Lummus Technology Inc. - Bloomfield NJ
International Classification:
C07C 5/327
US Classification:
585441, 585440
Abstract:
Processes are provided for the production of styrene monomer by oxidative dehydrogenation of EB using COas a soft oxidant. Carbon dioxide is used as the reaction diluent in one or more dehydrogenation reactors and to supply the heat required for the endothermic reaction of EB to styrene monomer. In the dehydrogenation reactors, two parallel reactions for styrene monomer formation occur simultaneously: (1) direct EB dehydrogenation to styrene monomer over a catalyst using heat provided by the carbon dioxide, and (2) oxidative dehydrogenation of EB with carbon dioxide to form styrene monomer.

Abstract:
The invention relates to a process for the production of alkylated aromatic compounds comprising introducing olefin and aromatic compounds into at least first and second vertically spaced catalytic reaction zones in an alkylation unit under alkylation reaction conditions to provide an alkylated product, wherein the second catalytic reaction zone is positioned above the first catalytic reaction zone; wherein aromatic compound from each of the at least first and second catalytic reaction zones are contacted with a cooling means for re-condensing at least a portion of the aromatic compounds vaporized from the exothermic heat of reaction of the alkylation process; and wherein the olefin is introduced into the at least first and second catalytic reaction zones via respective first and second olefin feed streams at respective olefin feed rates such as to maintain olefin partial pressures at inlets to at least first and second catalytic reaction zones which vary by less than about ten percent. The invention additionally relates to an apparatus for practicing the alkylation process of the invention.

Systems And Processes For Maintaining Ethylbenzene Dehydration Catalyst Activity
US Patent:
2021021, Jul 15, 2021
Filed:
Mar 26, 2021
Appl. No.:
17/214239
Inventors:
- Bloomfield NJ, US

Kevin John Schwint - Long Valley NJ, US
Assignee:
LUMMUS TECHNOLOGY LLC - Bloomfield NJ
International Classification:
C07C 5/367
C07C 5/32
C07C 5/32
Abstract:
Processes and systems for dehydrogenating ethylbenzene may include mixing a steam stream and an ethylbenzene stream to form a feed mixture. The ethylbenzene/steam feed mixture may then be fed to a dehydrogenation reactor containing an alkali metal promoted catalyst. A liquid, selected from an alkali metal liquid, an alkali metal compound liquid, or a liquid solution comprising an alkali metal, may be injected into a feed stream, such as the steam stream, the ethylbenzene stream, or the ethylbenzene/steam feed mixture. Following injection, the liquid vaporizes and disperses into the feed stream upstream of the dehydrogenation reactor. The liquid may be maintained as a liquid from a point upstream of injection to an injection nozzle. The liquid is dispersed through the injection nozzle, in liquid form, to form droplets of liquid dispersed in the feed stream, which evaporate and/or dissolve into the vaporous feed stream.
