Abstract:
1. A process for atomizing an FCC feed in an FCC feed injector comprising a plurality of mixing zones and a feed nozzle, comprising: (a) sparging a first atomizing fluid into the FCC feed through a first sparger in a first mixing zone, wherein the first sparger comprises orifices sized such that said atomizing fluid is sparged into the FCC feed at high velocities of greater than about 250 ft/sec (about 76 m/sec): (b) passing the mixture from the first mixing zone to a second mixing zone; (c) sparging, in the second mixing zone through a second sparger, a second atomizing fluid selected from steam, light hydrocarbon gas, inert gas, and combinations thereof into the mixture from the first mixing zone wherein the second sparger comprises orifices sized such that said atomizing fluid is sparged into the mixture from the first mixing zone at high velocities of greater than about 250 ft/sec (about 76 m/sec); and, (d) passing the resulting mixture from the second mixing zone through a feed nozzle.
