Exploring Opportunities for Ionic Liquid Capillary Columns in Petroleum Analysis
Petroleum samples consist of hundreds to thousands of components and require well-designed experiments to accurately determine quality and composition. The challenges with petroleum samples in this thesis are three-fold, focusing on: alkyl phosphate contamination, group-type composition, and biodiesel content. Alkyl phosphates in petroleum samples are of great interest to refineries that process oil produced from the Western Canadian Sedimentary Basin or other water-sensitive geologies. This
... geologies. This interest is due to the presence of residual phosphates from oil-based fracturing fluids causing premature fouling of equipment and poisoning of catalysts, leading to frequent maintenance outages. Group-type composition is of particular importance due to the correlation with emission and performance properties for fuel. ASTM D5186 has previously been used for this purpose, and relies on supercritical fluid chromatography. Unfortunately, this instrumentation is difficult to access and is not able to perform adequate separations on samples containing biodiesel. Our third challenge is one facing industry and consumers who operate in cold climates. Government regulations frequently mandate that industry use biodiesel in their operations to lessen the reliance on fossil fuels and decrease emissions of carbon dioxide .
