CHARACTERIZATION OF ASPHALTENES PRECIPITATED AT DIFFERENT SOLVENT POWER CONDITIONS USING MAGNETIC RESONANCE MASS SPECTROMETRY (MRMS)

摘要

Asphaltene precipitation is affected by factors such as heptane to crude oil ratio (HCOR). This means that for the same crude oil, a different set of molecules would precipitate forming a distinct asphaltene depending on these factors. It is expected that molecules more prone to precipitate are going to be those with the higher aromaticity, higher molecular weight and/or higher polar nature. Effect of solvent power on asphaltene properties HCOR is presented.
