Filed:

Nov 30, 2001

Appl. No.:

10/000867

Inventors:

Douglas E. Nelson - Brea CA, US
Robert W. Kuskie - Santa Ana CA, US
F. Emmet Bingham - Mission Viejo CA, US

Assignee:

Fluor Technologies Corporation - Aliso Viejo CA

International Classification:

B01F 3/00
B01F 3/04
B01F 5/00

US Classification:

422224, 422225, 422228, 422311

Abstract:

A quench zone mixing apparatus that occupies a low vertical height and has an improved mixing efficiency and fluid distribution across the catalyst surface includes a swirl chamber, a rough distribution network, and a distribution apparatus. In the swirl chamber, reactant fluid from a catalyst bed above is thoroughly mixed with a quench fluid by a swirling action. The mixed fluids exit the swirl chamber through an aperture to the rough distribution system where the fluids are radially distributed outward across the vessel to the distribution apparatus. The distribution apparatus includes a plate with a number of bubble caps and associated drip trays that multiply the liquid drip stream from the bubble caps to further symmetrically distribute the fluids across the catalyst surface. Alternatively, deflector baffles may be associated with the bubble caps to provide a wider and more uniform liquid distribution below the plate. The distribution apparatus can be used in the reaction vessel without the swirl chamber and rough distribution system, e. g.

International Classification:

B64D 37/00

US Classification:

701123

Abstract:

A method and apparatus for managing aircraft. Data about components for the aircraft is identified. Fuel efficiency of the aircraft is identified using the data about the components for the aircraft and a model of the aircraft. The model of the aircraft identifies fuel use. The aircraft is managed using the fuel efficiency identified for the aircraft.
