Claim 22:
23. The FCC control assembly of claim 21, wherein:
the FCC processing unit comprises a reactor positioned to receive the hydrocarbon feed and a catalyst, thereby to promote catalytic cracking of the hydrocarbon feed into the FCC effluent, the hydrocarbon feed and the catalyst providing a reaction mixture, and
one or more of (i) the second spectroscopic analyzer or (ii) one or more additional spectroscopic analyzers, is configured to analyze a reaction mixture sample taken from one or more locations of the reactor, the second spectroscopic analyzer and the one or more additional spectroscopic analyzers calibrated so as to generate standardized spectral responses, and
one or more of:
(i) the FCC control assembly further comprises additional spectroscopic analyzers configured to analyze respective reaction mixture samples taken from two or more locations of the reactor, the additional spectroscopic analyzers being calibrated to generate standardized spectral responses,
(ii) the FCC control assembly further comprises additional spectroscopic analyzers configured to analyze two or more respective reaction mixture samples taken from two or more different points along a height of the riser, the additional spectroscopic analyzers being calibrated so as to generate standardized spectral responses, or
(iii) the FCC processing unit comprises a riser associated with the reactor, and the second spectroscopic analyzer is configured to analyze the reaction mixture sample at an outlet of the riser.
