11/832147
Inventors:
Keith A. Couch - Arlington Heights IL, US
Xin X. Zhu - Long Grove IL, US
James P. Glavin - Naperville IL, US
Assignee:
UOP LLC - Des Plaines IL
International Classification:
C10G 57/00
US Classification:
208113, 422139, 422141, 422143, 422144, 422145, 422146, 422147, 60648, 60676, 502 34, 502 38, 502 50, 502 55, 502 56
Abstract:
Disclosed is a process for combusting dry gas to heat the air supplied to an FCC regenerator to increase its temperature and minimize production of undesirable combustion products. Preferably, the dry gas is a selected FCC product gas. Alternatively or additionally, dry gas from an FCC product stream is separated and delivered to an expander to recover power before combustion.

Fluid Catalytic Cracking System

US Patent:
8246914, Aug 21, 2012
Filed:
Dec 22, 2008
Appl. No.:
12/340945
Inventors:
Robert L. Mehlberg - Wheaton IL, US
Keith Allen Couch - Arlington Heights IL, US
Brian W. Hedrick - Oregon IL, US
Zhihao Fei - Naperville IL, US
Assignee:
UOP LLC - Des Plaines IL
International Classification:
B01J 8/24, C07C 4/06
US Classification:
422139, 422622, 422234, 585648, 585651, 585653, 208 72
Abstract:
One exemplary embodiment can be a fluid catalytic cracking system. The system can include a reaction zone operating at conditions to facilitate olefin production and including at least one riser. The at least one riser can receive a first feed having a boiling point of about 180-about 800° C. , and a second feed having more than about 70%, by weight, of one or more C4 olefins.

Advanced Elevated Feed Distribution Apparatus And Process For Large Diameter Fcc Reactor Risers

US Patent:
2011019, Aug 18, 2011
Filed:
Feb 17, 2011
Appl. No.:
13/029274
Inventors:
Keith A. Couch - Arlington Heights IL, US
Robert L. Mehlberg - Wheaton IL, US
Assignee:
UOP LLC - Des Plaines IL
International Classification:
C10G 11/00, B01J 19/00
US Classification:
208113, 422129
Abstract:
An FCC process and apparatus may include injecting hydrocarbon feedstock at different radial positions while at the same elevation inside a riser. Multiple distributors may be used to position the tips for injecting feedstock at multiple radial positions. The distributors with tips more deeply positioned in the riser will penetrate a dense catalyst column we discovered generates in risers of larger diameter over 1.3 meters.

Fluid Catalytic Cracking Steam Pressure Letdown Power Recovery System And Process

US Patent:
7757493, Jul 20, 2010
Filed:
Mar 7, 2006
Appl. No.:
11/369296
Inventors:
Leonard E. Bell - Streamwood IL, US
Keith A. Couch - Arlington Heights IL, US
Assignee:
UOP LLC - Des Plaines IL
International Classification:
F02C 3/30
US Classification:
60775, 60772, 60 39182
Abstract:
A system and method are provided for recovering power from hot flue gas of a catalyst regenerator in an FCC unit and an integrated fluid catalytic cracking steam pressure letdown. The system includes a flue gas power recovery system including an expander and a turbine for generating power by letting down steam from a higher pressure to a lower pressure for use in a refinery process such as an FCC unit.

Apparatus And Process For Regenerator Mixing

US Patent:
7758820, Jul 20, 2010
Filed:
Dec 21, 2006
Appl. No.:
11/614830
Inventors:
Robert L. Mehlberg - Wheaton IL, US
Reza Mohammad Mostofi Ashtiani - Naperville IL, US
Keith A. Couch - Arlington Heights IL, US
Assignee:
UOP LLC - Des Plaines IL
International Classification:
B01D 50/00
US Classification:
422178, 502 34
Abstract:
Apparatus and process is provided for increasing mixing in a regenerator. Streamlines of gas and some catalyst may form in a regenerator as a result of cyclone inlet horns positioned in the same direction. Overall mixing in the regenerator may decrease because of these streamlines. A dampening device may be used to interrupt the streamlines and increase mixing in the regenerator. The dampening device may be a baffle and direct streamlines from the outside of the chamber toward the center to collide and mix. In another embodiment, a dampening device may be a secondary disengager such as a T-disengager or an inverted can arrangement that may discharge gas and catalyst near the center of the upper chamber and interrupt the streamlines. In another embodiment, a dampening device may have swirl arms that redirect stream lines counter to the direction of flow.
