Abstract
A novel process for atomizing a liquid stream is disclosed and includes introducing the liquid to a nozzle including a fluid conduit, an outlet orifice and swirl-imparting means thereby at least partially atomizing the liquid stream to form an atomized liquid stream. Preferably, the atomized liquid stream does not contact a fluid deflecting device upon exit from the outlet orifice. This novel process can be utilized in a fluidized catalytic cracking process prior to contact with a fluidized catalyst or in a coking process for atomizing an oil stream.
Claims14
A method for atomizing a liquid stream comprising introducing said liquid stream and introducing an atomizing enhancing medium to the inlet of a nozzle comprising a fluid conduit having an outlet orifice having a diameter and swirl-imparting means within said conduit for imparting a rotational component of motion to liquid flowing therethrough;
- wherein said swirl-imparting means has an opening therethrough transversely of said fluid conduit which is substantially smaller than said outlet orifice and is in coaxial alignment therewith, said swirl-imparting means including sinusoidal portions in edge-to-edge relation spanning adjacent semi-circular segments of said fluid conduit, each sinusoidal portion including convex and concave lobes, said convex lobes being disposed toward the inlet end of said conduit and said concave lobes being offset axially from said convex lobes a distance approximately equal to the diameter of said outlet orifice, said convex and concave lobes being in alternate circumferential sequence in said fluid conduit;
- and
- withdrawing said liquid stream and said atomizing enhancing medium from said outlet orifice of said nozzle thereby at least partially atomizing said liquid stream to form an atomized liquid stream;
- wherein said atomized liquid stream does not contact a fluid deflecting device upon exit from said outlet orifice.
