Abstract: A method of screening a hydrocarbon stream for potential toxicological hazards. The method involves providing a hydrocarbon stream; conducting 2-dimensional gas chromatography (2D-GC) analysis to quantify saturates and aromatic distribution in the hydrocarbon stream; identifying 2-8 ring aromatic distribution and weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis; relating the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis to a mutagenicity index (MI), in which the MI is determined in accordance with ASTM Standard Method E 1687; and assessing a potential toxicological hazard of the hydrocarbon stream based on the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis and a MI threshold value. The 2-8 ring aromatic distribution preferably includes 3-6 ring aromatics, more preferably 3.5-5.5 ring aromatics. The 2-8 ring aromatic distribution includes mono alkylated and multi alkylated aromatic molecules.

Abstract: Methods for generating molecular formula distributions beyond a predetermined threshold for a petroleum stream are disclosed. An initial molecular formula distribution within a predetermined threshold is obtained for a petroleum stream. A correlation between two or more molecular properties of the initial molecular formula distribution is identified, and the initial molecular formula distribution is extrapolated beyond the predetermined threshold along the correlation. The extrapolated molecular formula is renormalized based on renormalization data obtained from the sample. The renormalized molecular formula distribution can then be blended with the initial molecular formula distribution, reconciled to secondary analytical measurements, and/or used to create a model of composition and/or a molecular composition-based model of a resid upgrading process. Systems for implementing the methods are also disclosed.

Abstract: A method to determine the model-of-composition of a vacuum resid in which the resid is separated into fractions including the DAO fraction which is then separated into chemical classes including saturates, aromatics, sulfides and polars by a combination of soft ionization methods. The results of the ionization analysis are reconciled with other analysis such as bulk analysis, then consolidated to generate the modeol-of composition.
