Abstract:
Asphaltenes in crude oil can foul up lines and cause significant issues for any processing plant. Therefore, their accurate quantification on a reasonable timescale is paramount. Currently, asphaltenes are quantified via a "wet chemistry" method that involves repeated steps of dissolving, then precipitating out (or flocculating), then filtering out the asphaltenes to be weighed. This process is slow, inefficient, unrepeatable, and not entirely accurate. Electron Paramagnetic Resonance (EPR) offers a fast, efficient, repeatable, and accurate method to quantify the amount of asphaltene present in a sample with small sample sizes and next to no wasted solvents.
