Integrated Processes For Propylene Production And Recovery

View page
US Patent:
20100331589, Dec 30, 2010
Filed:
Jun 29, 2009
Appl. No.:
12/493374
Inventors:
Joseph E. ZIMMERMANN - Arlington Heights IL, US
Larry C. Erickson - Arlington Heights IL, US
Gregory J. Nedohin - Des Plaines IL, US
International Classification:
C07C 5/333
US Classification:
585314
Abstract:
Processes utilizing the integration of (i) processes and the associated equipment used to purify and recover propylene from propane- and/or C+-containing refinery hydrocarbon streams, with (ii) catalytic dehydrogenation are disclosed. This integration allows for elimination of some or all of the conventional fractionation section of the dehydrogenation process, normally used to purify propylene from unconverted propane in the reactor effluent. Significant capital and utility savings are therefore attained.

Adjustable Lift Engager

US Patent:
20190184359, Jun 20, 2019
Filed:
Dec 20, 2017
Appl. No.:
15/849167
Inventors:
- Des Plaines IL, US
Gregory James Nedohin - Des Plaines IL, US
International Classification:
B01J 8/00
B01J 8/12
C10G 35/12
C10G 49/00
Abstract:
A lift engager for providing a stream of fluidized catalyst particles with an adjustable conduit and process using the lift engager. The lift engager includes a vessel with an inlet configured to receive catalyst from a reaction zone. A first conduit, within the vessel, is configured to supply lift gas into the lift engager. The first conduit includes a fixed member and a movable member secured to the fixed member and is configured to adjust a length of the first conduit within the vessel. A second conduit inside the first conduit and configured to provide fluidized catalyst to a regeneration zone.

US Patent:
20190127298, May 2, 2019
Filed:
Nov 1, 2018
Appl. No.:
16/178413
Inventors:
- Des Plaines IL, US
Michael J. Vetter - Schaumburg IL, US
Gregory J. Nedohin - Des Plaines IL, US
Clayton C. Sadler - Arlington Heights IL, US
International Classification:
C07C 5/333
B01J 35/02
B01J 8/02
Abstract:
Large pill dehydrogenation catalysts and large screens slot width are combined in dehydrogenation units to reduce the pressure drop across the catalyst bed and reactor screens compared to conventional screen and catalyst size combinations. The catalyst has an average pill diameter in the range of 1.6 mm to 3.0 mm, and the slot width of the screen is in the range of about 30% to about 60% of the pill diameter.
