| description | A nozzle and method of use thereof is provided for atomizing a liquid stream. The nozzle is particularly useful for atomizing a hydrocarbon feed into a catalytic cracking zone of a fluidized catalytic cracking (FCC) process. The nozzle includes a primary conduit for receiving a liquid stream and a secondary conduit for receiving a dispersion medium. At least a portion of the secondary conduit is positioned within the primary conduit to form a passageway for the liquid stream between the inner surface of the primary conduit and outer surface of secondary conduit. The dispersion medium and liquid stream are combined in a mixing zone that is located between the outlet of the secondary conduit and the outlet of the primary conduit. In the mixing zone, the primary conduit inner surface is gradually tapered so the cross-sectional area of the primary conduit outlet is decreased relative to the cross-sectional area of the primary conduit inlet. The primary conduit outlet has lip that is useful for shearing or severing the liquid stream as it exits the primary conduit. |
