Abstract
The present invention is a method to determine the composition of a hydrocarbon feedstream from a small sample of hydrocarbons including the steps analyzing the sample with a combination of chromatograph and mass spectrometer, and reconciling output from step a) with other analytical measurements to determine to determine the composition of the hydrocarbon feedstream.
Claims24
A method to determine the model-of-composition of a petroleum or hydrocarbon sample from a small sample of said petroleum or hydrocarbon sample comprising
- a) obtaining measurements by analyzing the whole small sample absent separation into fractions with a combination of chromatograph and mass spectromer,
- b) quantifying output from step a) by applying response factors and normalizing petroleum or hydrocarbon classes to that measured by super critical fluid chromatography or other chromatographic techniques,
- c) reconciling the output from step b) with other analytical measurements that determine hydrocarbon and petroleum properties to obtain a model-of-composition of the petroleum or hydrocarbon sample.
