Method For Maintaining Heat Balance In A Fluidized Bed Catalytic Cracking Unit
View pageUS Patent:
6558531, May 6, 2003
Filed:
Mar 13, 2001
Appl. No.:
09/804721

Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C10G 1100
US Classification:
208113, 208159, 502 45, 502 46, 502 49
Abstract:
The invention relates to a process for maintaining heat balance in a fluidized bed catalytic cracking unit. More specifically, the invention relates to a combustion control method capable of maintaining or restoring heat balance by conducting, under appropriate conditions, fuel and an oxygen-containing gas to a transfer line. The transfer line conducts effluent including spent catalyst and combustion products to the units catalyst regeneration zone.

52756416, Jan 4, 1994
Filed:
Aug 26, 1992
Appl. No.:
7/935320
Inventors:
Robert F. Tammera - West Orange NJ
Donald F. Shaw - Denville NJ
Kenneth J. Reinman - Long Valley NJ
George Melfi - Whippany NJ

Assignee:
Exxon Research & Engineering Co. - Florham Park NJ
International Classification:
B01D 4512
US Classification:
95271
Abstract:
Accordingly, the present invention, in one embodiment, encompasses an apparatus for the fluidized catalytic cracking of a hydrocarbon feed comprising: a riser which is generally vertically positioned within a catalyst disengaging zone and which has a plurality of openings around the circumference of the riser at its discharge end. The openings in the riser have a vertical stub portion that extends tangentially outwardly from the riser and communicates with a first end of an upwardly sloping curvilinear tunnel that terminates at a second end. The second end of the tunnel opens into a tangential opening in the primary cyclone. The area of the opening of the first end of the tunnel is larger than the area of the opening of the second end of the tunnel.
