ABSTRACT:
A method of converting a side by side FCC arrangement adds a new reactor vessel and uses the regenerator vessel and reactor vessel to provide a regeneration section having at least three stages of regeneration that is used as part of an enlarged FCC process. In simplest form, the conversion method calls for the use of the regeneration vessel as a first-stage regeneration zone, the use of the reactor vessel as a second-stage regeneration zone, and the use of the spent catalyst stripper as a third stage of regeneration. This arrangement provides a second stage of regeneration that is positioned to facilitate the addition of partially regenerated catalyst to the stripping zone to facilitate the operation of a hot catalyst stripping section.
