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.
