Claim 25:
26. A fluid catalytic cracking (FCC) process controller to enhance control of a hydrotreating and fluid catalytic cracking (FCC) process associated with a refining operation, the FCC process controller in communication with one or more spectroscopic analyzers and a cat feed hydrotreater (CFH) processing unit associated with the refining operation and positioned to produce CFH unit material, the FCC process controller configured to:
predict one or more hydrocarbon feedstock sample properties associated with a hydrocarbon feedstock sample based at least in part on hydrocarbon feedstock sample spectra generated by the one or more spectroscopic analyzers;
predict one or more CFH unit material sample properties associated with a CFH unit material sample based at least in part on CFH unit material sample spectra generated by the one or more spectroscopic analyzers; and
control, during the FCC process, based at least in part on the one or more hydrocarbon feedstock sample properties or the one or more CFH unit material sample properties, one or more of:
(i) one or more hydrocarbon feedstock properties associated with hydrocarbon feedstock supplied to the CFH processing unit,
(ii) one or more CFH material properties associated with CFH unit material supplied to the one or more first processing units,
(iii) one or more intermediates properties associated with intermediate materials produced by one or more first processing units comprising an FCC processing unit,
(iv) operation of the CFH processing unit,
(v) operation of the one or more first processing units,
(vi) one or more unit materials properties associated with one or more unit materials produced by the one or more first processing units, or
(vii) operation of one or more second processing units positioned downstream relative to the one or more first processing units,
so that the control causes the FCC process to produce one or more of:
(a) one or more CFH unit materials each having one or more properties within a selected range of one or more target properties of the one or more CFH materials,
(b) one or more intermediate materials each having one or more properties within a selected range of one or more target properties of the one or more intermediate materials,
(c) one or more unit materials each having one or more properties within a selected range of one or more target properties of the one or more unit materials, or
(d) one or more downstream materials each having one or more properties within a selected range of one or more target properties of the one or more downstream materials,
thereby to cause the FCC process to achieve material outputs that more accurately and responsively converge on one or more of the target properties.
