Abstract
An apparatus for multistage, hot stripping of spent FCC catalyst in a regenerator having a stripper supported by the regenerator is disclosed. A secondary stripper, under the conventional primary stripper, is heated indirectly by immersion in a dense bed of hot regenerated catalyst, or heat exchange with a dilute phase transport riser encompassing the primary stripper standpipe and secondary stripper, or by direct contact heat exchange with added hot regenerated catalyst. Vapor from the secondary stripper passes through the primary stripper without contacting spent catalyst in the primary stripper.
