Appl. No.:

11/499788

Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ

International Classification:

G01N 31/00

US Classification:

436 60, 436173

Abstract:

The present invention is a method to determine the TAN and TAN as a function of boiling point for a hydrocarbon feedstream using an electrospray ionization mass spectrometer (ESI-MS). The steps of the method include determining the signal as a function of mass from the ESI-MS while minimizing the formation of oligomers and fragmentation of the molecular species in the feedstream and then determining the TAN from the signals. The TAN is also determined as a function of boiling point.

International Classification:

G01J 3/28
G06T 7/90
G06T 7/00

Abstract:

Systems, methods and computer program products for segmenting colors in a sample image comprised of pixels using a processor configured by code executing for selecting at least one color value present within the sample image and for each color selected from the sample image comparing the color values of each pixel of the sample image to the selected color value and averaging the color values of each pixels of the sample image having a color value difference below a pre-determined threshold. The method also includes outputting the average color value as a color value data object; and associating each averaged color value with sample image.

Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ

International Classification:

G01N 30/72

US Classification:

73 2337

Abstract:

Petroleum or other hydrocarbon samples can be analyzed in parallel by 1) GC-field ionization Time of Flight Mass Spectrometer (GC-FI-TOF MS) and 2) two dimensional gas chromatography (2D-GC) equipped with a flame ionization detector (FID). The combined techniques allow for improved quantitative characterization of the compounds within a hydrocarbon sample. The techniques can be combined by correlating the 2D-GC FID data with the GC-FI-TOF MS data based on correlation of compound classes, correlation of retention windows within a compound class, correlation of individual compounds, such as paraffins, or a combination thereof.

International Classification:

H01J 49/00

US Classification:

250282

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 analyses are reconciled with other analyses such as bulk analysis, then consolidated to generate the modeol-of composition.
