Historically refinery control engineers are familiar with GC derived chemical properties such as aromatics, benzene, PONA, olefins in wt% or vol%, as well as physical properties such as distillation, viscosity, conradson carbon, sulfur, density, etc. We have developed generally applicable multivariate regression methods that allow many of these familiar chemical and physical properties to be derived from quantitative 1H or 13C NMR data. We have also developed magnetic field independent data manipulation methods that allow 1H or 13C NMR derived parameters to be utilized as the X matrix “spectral” data rather than the spectra themselves. This allows field independent models to be developed as these parameters are calculated from the spectrum and are the same regardless of the magnetic field strength at which the NMR data was collected. This has implications with respect to calibration transfer between laboratories and analyzers. In this work we describe the application of these methods to feed-streams to a residual catalytic cracker (RCC), which represents the core gasoline and diesel production facility in many refineries.
