Process for determining the polarity of a crude oil
Abstract
This patent describes a process for determining the relative polarity of a crude oil or fraction thereof. It comprises: contacting a known test substance with a stationary phase of the crude oil or fraction in a gas chromatography column, and measuring the interaction between the test substance and the oil; contacting the known test substance with a stationary phase of a non-polar second substance in a gas chromatography column and measuring the interaction between the test substance and the non-polar second substance; and determining the polarity of the crude oil relative to the non-polar second substance from the measurements obtained.
