Multi-Dimensional High Performance Liquid Chromatographic Separation Technique (Star7) For Quantitative Determinations Of 7 Fractions In Heavy Petroleum Streams Boiling Above 550 Degrees F

View page
US Patent:
8114678, Feb 14, 2012
Filed:
Feb 5, 2010
Appl. No.:
12/658566
Inventors:
Birbal Chawla - Mickleton NJ, US
Larry A. Green - Mickleton NJ, US
Assignee:
ExxonMobil Research & Engineering Company - Annandale NJ
International Classification:
G01N 30/02
B01D 15/00
US Classification:
436161, 436139, 422 681, 422 70, 210660
Abstract:
The present invention provides quantitation of seven classes of compounds (saturates, 1-4+ ring aromatics, sulfides, and polars) present in petroleum streams boiling from 550-1050 F. Operating the present invention in the preparative mode will allow us to load and collect multi-milligram amounts of material. In the present invention, all seven fractions are produced in a single run, whereas the most commonly used preparative liquid chromatographic separations requires two or more large scale separations to generate similar fractions. The present invention uses 100 times less solvent. The present invention protocol provides a quicker and cheaper alternative to most commonly used preparative liquid chromatographic separations and is flexible enough to target many refining and chemicals problems.

Fractionation Of De-Asphalted Oil Of Vacuum Resid Using Preparative High Performance Liquid Chromatographic Separations

View page
US Patent:
20130055795, Mar 7, 2013
Filed:
Sep 1, 2011
Appl. No.:
13/223739
Inventors:
Birbal Chawla - Cherry Hill NJ, US
Bryan E. Hagee - Glassboro NJ, US
Larry A. Green - Mickleton NJ, US
Frank P. DiSanzo - Cherry Hill NJ, US
Assignee:
EXXONMOBIL RESEARCH AND ENGINEERING COMPANY - Annandale NJ
International Classification:
G01N 30/02
US Classification:
73 6153
Abstract:
Two quantitative separation approaches to fractionate de-asphalted oils (DAOs) into seven classes of compounds (saturates, 1-4 ring-aromatics, sulfides, and polars). In the first step (named as “SGS”) of present invention, the DAO of a petroleum vacuum resid is separated in to four classes of compounds, namely saturates, aromatics, and sulfides. In this first step of separation, about 3 grams of a DAO can be separated. Whereas in the second step (named as “ARC” separation) of invention, only less than 300 mg of the aromatic fraction obtained in “SGS” (described above) can be further fractionated at very low temperature (about −40 degrees centigrade) into 4 fractions, namely 1-ring, 2-ring, 3-ring, and 4-ring aromatics. The present invention protocol is suitable for a wide range of compositionally different DAOs of petroleum vacuum resids.

US Patent:
54116589, May 2, 1995
Filed:
Oct 8, 1993
Appl. No.:
8/133403
Inventors:
Birbal Chawla - Cherry Hill NJ
Dominik N. Mazzone - Wenonah NJ
Michael S. Sarli - Haddonfield NJ
Stuart S. Shih - Cherry Hill NJ
Hye Kyung C. Timken - Woodbury NJ
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
C10G 6902
US Classification:
208 89
Abstract:
Low sulfur gasoline of relatively high octane number is produced from a cracked, sulfur-containing olefinic naphthas by hydrodesulfurization followed by treatment over an acidic catalyst comprising zeolite beta with a metal hydrogenation component, preferably a mild hydrogenation component such as molybdenum. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380. degree. F. (about 193. degree. C. ), improvements in both product octane and yield relative to the feed may be obtained.

Determination Of Asphaltene Solubility Distribution

View page
US Patent:
20210018477, Jan 21, 2021
Filed:
Jul 16, 2020
Appl. No.:
16/930691
Inventors:
- Annandale NJ, US
Bridget E. Lang - Morristown NJ, US
Birbal Chawla - Sterling VA, US
International Classification:
G01N 31/02
G01N 13/00
G01N 21/47
G01N 33/28
Abstract:
Systems and methods are provided for determining an asphaltene solubility distribution for a petroleum sample and/or other hydrocarbon sample. A vessel for performing the method can include both packing material(s) and sidewall(s) that correspond to substantially inert materials. The vessel can initially contain a precipitating solvent suitable for causing precipitation of asphaltenes from a hydrocarbon sample. Examples of a precipitating solvents can correspond to n-heptane, toluene, and mixtures of n-heptane and toluene. The petroleum sample is then introduced into the vessel, along with a carrier solvent. The volume of the precipitating solvent can be large relative to the sample, so that the solubility of asphaltenes in the sample becomes dependent on the properties of the precipitating solvent. If asphaltenes are precipitated, the asphaltenes can be washed out of the column using a dissolution solvent. The asphaltenes washed out using the dissolution solvent can then be characterized to determine a total asphaltene content.

Preparatory High Performance Liquid Chromatographic (Hplc) Separation System And Technique For Quantitative Fractionation Of Total Vacuum Resid

View page
US Patent:
20140166542, Jun 19, 2014
Filed:
Dec 18, 2012
Appl. No.:
13/718064
Inventors:
- Annandale NJ, US
Birbal CHAWLA - Cherry Hill NJ, US
Assignee:
EXXONMOBIL RESEARCH AND ENGINEERING COMPANY - Annandale NJ
International Classification:
C10G 7/08
G01N 30/02
US Classification:
208309, 73 6153
Abstract:
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.
