Claim 16:
17. The method of claim 1, 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
the method further comprises analyzing, via one or more spectroscopic analyzers, reaction mixture samples taken from one or more locations of the reactor to obtain unit material samples of one or more of catalyst stripper vapor, reactor dilute vapor, riser vapor, or reactor effluent, thereby to determine one or more of respective catalyst stripper vapor yield, reactor dilute vapor yield, riser vapor yield, or reactor effluent yield.
