  • Heavy hydrocarbon feed atomization
    Patent number: 5306418
    Abstract: A nozzle, and FCC process using the nozzle for atomizing heavy feed to a riser reactor, are disclosed. A liquid feed stream is atomized by radial out-to-in impingement of atomizing vapor, discharged onto an impingement plug in an annular expansion region, then sprayed through an outlet. Baffles at the expansion region outlet, and an orifice outlet improve feed atomization and feed/FCC catalyst contact in a riser reactor. The nozzle may be used to distribute liquid over other reactor beds, or to add liquid to distillation columns.
    Type: Grant
    Filed: April 2, 1992
    Date of Patent: April 26, 1994
    Assignees: Mobil Oil Corporation, M. W. Kellogg Company
    Inventors: Suisheng M. Dou, Allen R. Hansen, Steven C. Heidenreich, William J. Hillier, Phillip K. Niccum, Maury I. Schlossman
