Method of Assaying a Hydrocarbon-Containing Feedstock
First Claim
1. A method of assaying a hydrocarbon-containing feedstock, the method comprising:
- (a) measuring boiling profile and at least one other property of the hydrocarbon-containing feedstock with at least two different laboratory-independent techniques wherein each laboratory-independent technique is selected to be predictive of each respective property;
(b) transmitting the measurements made in step (a) to a processor capable of reconstructing a determinative assay of the hydrocarbon-containing feedstock from the measurements; and
,(c) reconstructing a determinative assay of the hydrocarbon-containing feedstock from the measurements.

Abstract
Disclosed herein is a method of assaying a crude oil, the method includes measuring at least two selected properties of the crude oil with one or more laboratory-independent devices using at least two different techniques wherein each technique is predictive of each respective property, transmitting the measured properties to a processor capable of reconstructing a determinative assay of the crude oil from the measured properties, and reconstructing a determinative assay of the crude oil from the measured properties. The disclosed method provides real-time information of a refinery feedstock such that, for example, a trader negotiating the sale of the product has accurate assay information on which to determine whether to sell or purchase the product.
