ABSTRACT:
A process and apparatus for achieving hot catalyst stripping of spent FCC catalyst in a stripper mounted over a bubbling bed regenerator. Hot catalyst stripping is achieved by indirect transfer of heat from the regenerator to the stripper. Heat pipes, surface modifications such as fins on the stripper vessel, or use of a stripper in, or connective with, a heat exchange tube bundle may be used to heat spent catalyst with heat from the regenerator dilute phase, without transferring catalyst from the regenerator. The benefits of hotter catalyst stripping are achieved, without increasing catalyst traffic in the regenerator.
