Abstract:
1. A method to control an xBOB output stream, which comprises: (a) spectroscopically analyzing first xBOB stream to produce a spectrum; (b) correcting said spectrum mathematically to produce a corrected spectra; (c) applying a calibration model to said corrected spectra to produce predicted laboratory results, wherein said calibration model correlates a first dataset of previously-obtained corrected spectra of two or more different xBOB mixtures with a second dataset of previously-obtained corrected spectra obtained by spectroscopically analyzing two or more different finished gasoline mixtures, wherein each finished gasoline mixture comprises a distinct xBOB mixture combined with a known quantity of an oxygenate; (d) transferring said predicted laboratory results to a control system wherein said control system modifys the ratio of blendstock components of said xBOB stream based on said predicted laboratory results to produce an xBOB output stream, such that when said xBOB stream is combined with a fixed, known quantity of a predetermined oxygenate an oxygenate-containing gasoline product is produced having preset physical properties.
