US Patent:

7515781, Apr 7, 2009

Filed:

Jul 7, 2006

Appl. No.:

11/483024

Inventors:

Robert J. Chimenti - Short Hills NJ, US
Bruce N. Perry - Flemington NJ, US

Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ

International Classification:

G02B 6/00

US Classification:

385 12, 385 13

Abstract:

The present invention includes a method and system of measuring alteration, alteration type, and alteration-causing species in process fluids and equipment and for controlling the process feeds and conditions to maximize the yields and equipment lifetime by minimizing the alteration. The invention includes an optical sensor comprising an optical fiber, a fiber grating written within the optical fiber, strain-tuned elements fixed to the optical fiber and an unaltered element, and an altered element fixed to the unaltered element.

International Classification:

G06F 15/18

US Classification:

706 12

Abstract:

The present invention is a method to determine models to predict physical or chemical properties of a petroleum fluid when such properties of such fluids cannot be measured by conventional analytical methods. The invention includes the steps of determining one or more models that predict one or more predetermined properties from a set of oils whose optical spectra and properties are known wherein a model corresponds to each predetermined property which is related to the spectrum, estimating the quality of the models, estimating the predictive quality for samples with unknown properties, augmenting the spectrum with shape parameters and/or properties that are predicted by the step above, and determining the quality and predictive quality of the models. The models are then used to predict properties of very small samples.

Appl. No.:

6/574130

Inventors:

Azriel Z. Genack - New York NY
Bruce N. Perry - Flemington NJ

Assignee:

Exxon Research and Engineering Co. - Florham Park NJ

International Classification:

G01J 344

US Classification:

356301

Abstract:
