PREPARATORY HIGH PERFORMANCE LIQUID CHROMATOGRAPHIC (HPLC) SEPARATION SYSTEM AND TECHNIQUE FOR QUANTITATIVE FRACTIONATION OF TOTAL VACUUM RESID

PREPARATORY HIGH PERFORMANCE LIQUID CHROMATOGRAPHIC (HPLC) SEPARATION SYSTEM AND TECHNIQUE FOR QUANTITATIVE FRACTIONATION OF TOTAL VACUUM RESID

A method and system for conducting chromatographic analysis of a total vacuum resid to provide quantification of eight classes of compounds (i.e., asphaltenes, saturates, 1-4+ ring aromatics, sulfides, and polars) contained within the total vacuum resid without prior de-asphalting are disclosed. The...

Zusammenfassung:A method and system for conducting chromatographic analysis of a total vacuum resid to provide quantification of eight classes of compounds (i.e., asphaltenes, saturates, 1-4+ ring aromatics, sulfides, and polars) contained within the total vacuum resid without prior de-asphalting are disclosed. The system is also capable of conducting chromatographic analysis of a vacuum gas oils and de-asphalted oils to provide quantification of seven classes of compounds (i.e., saturates, 1-4+ ring aromatics, sulfides, and polars). The system is also capable of conducting chromatographic analysis of a resid to identity the presence of and provide quantification of asphaltenes.
