摘要
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.
