Embodiment Construction

[0044] exist Figure 1-8 The nozzle of the first embodiment of the present invention is generally indicated by reference numeral 10 . The nozzle 10 is used to discharge the first and second fluids as atomized jets into a container 20 defining an inner contour. In one embodiment of the invention, the first fluid is oil, the second fluid is gas or steam, and the vessel is a catalytic cracking vessel. However, as one of ordinary skill in the relevant art will recognize based on the teachings herein, the nozzles of the present invention may be equally used with any of a variety of different types of fluids, as well as many different types of fluids now known or hereafter known. Any application of type .

[0045] The nozzle 10 includes an inlet portion 12 defining at least one inlet conduit 14 for receiving at least one fluid, in one embodiment first and second fluids. The outlet portion 16 of the nozzle defines an outer surface 18 conforming substantially to the interior contou...

Abstract

A nozzle for discharging first and second fluids in a spray pattern into a vessel, such as oil and steam in a catalytic cracking unit, includes various configurations for preventing erosion of the outlet portion of the nozzle that otherwise might be due, for example, to contact with a catalyst or other predetermined substance. In one such nozzle, the exterior surface of the outlet portion substantially conforms to the internal contour of the vessel. In another such nozzle, the outlet portion defines a plurality of substantially concentric, substantially elliptical-shaped outlet apertures. In another nozzle, the outlet portion is formed of ceramic and is connected to the inlet portion by a metal connector. In another nozzle, the outlet portion defines a plurality of apertures angularly spaced about a peripheral region of the outlet portion for discharging a substantially flat fan spray pattern, and a second outlet portion extending along an upstream portion of the outlet portion for discharging at least part of its spray to prevent any catalyst from contactin the downstream surfaces of the outlet ortion.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 60 / 741,022, filed November 29, 2005, the entire contents of which are incorporated herein by reference as part of this disclosure. technical field [0003] The present invention relates to nozzles, and more particularly to nozzles for mixing liquid and gas into an atomized jet. Background technique [0004] Fluid Catalytic Cracking (FCC) is one of the main refining processes used in the oil refining industry. The FCC process is used to crack materials consisting essentially of petroleum-based hydrocarbons to produce products such as fuel oil and heating oil for internal combustion engines. The cracking process is typically carried out in a vertically oriented pipeline or riser comprising a reaction vessel forming part of an FCC system. During this process, hot catalyst particles in an aerated (fluidized) state are typically introduced into the bottom ...
