1. A method to enhance a fluid catalytic cracking (FCC) process associated with a refining operation, during the FCC process, the method comprising:
supplying a hydrocarbon feedstock to one or more FCC processing units associated with the refining operation, the hydrocarbon feedstock having one or more hydrocarbon feedstock parameters;
operating the one or more first FCC processing units, thereby to produce one or more corresponding unit materials, the one or more corresponding unit materials comprising one or more of intermediate materials or unit product materials comprising FCC effluent;
conditioning a hydrocarbon feedstock sample to one or more of filter the hydrocarbon feedstock sample, change a temperature of the hydrocarbon feedstock sample, dilute the hydrocarbon feedstock sample in solvent, or degas the hydrocarbon feedstock sample;
analyzing the hydrocarbon feedstock sample via a first spectroscopic analyzer, thereby to provide hydrocarbon feedstock sample spectra;
conditioning a unit material sample to one or more of filter the unit material sample, change a temperature of the unit material sample, dilute the unit material sample in solvent, or degas the unit material sample;
analyzing the unit material sample via one or more of the first spectroscopic analyzer or a second spectroscopic analyzer, thereby to provide unit material sample spectra, the one or more of the first spectroscopic analyzer or the second spectroscopic analyzer being calibrated to generate standardized spectral responses;
predicting one or more hydrocarbon feedstock sample properties associated with the hydrocarbon feedstock sample based at least in part on the hydrocarbon feedstock sample spectra;
predicting one or more unit material sample properties associated with the unit material sample based at least in part on the unit material sample spectra; and
prescriptively controlling, during the FCC process, via one or more FCC process controllers based at least in part on the one or more hydrocarbon feedstock parameters, the one or more hydrocarbon feedstock sample properties, and the one or more unit material sample properties, one or more of:
(i) the one or more hydrocarbon feedstock parameters associated with the hydrocarbon feedstock supplied to the one or more FCC processing units,
(ii) one or more intermediates properties associated with the intermediate materials produced by one or more of the FCC processing units,
(iii) operation of the one or more FCC processing units,
(iv) one or more unit materials properties associated with the one or more unit materials, or
(v) operation of one or more downstream processing units positioned downstream relative to the one or more first FCC processing units,
so that the prescriptively controlling during the FCC process causes the FCC process to produce one or more of:
(a) 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,
(b) 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
(c) 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.
