Abstract:
The quantitation of olefins in petroleum products is of great industrial interest, especially for those involved in transportation and upgrading of bitumen and heavier crudes by thermal cracking. Olefins and di-olefins produced in small quantities during the thermal upgrading processes have a tendency to undergo polymerization reactions causing instability to the finished products. The purpose of this research project was to identify and quantify olefins using Gas Chromatography (GC) and a Vacuum Ultraviolet (VUV) detector. The focus matrix was condensate but it has been used on upgraded bitumen. The research has resulted in method detection limits (MDLs) of more than 45 olefins and di-olefins including several conjugated olefins at very low part per million (ppm) levels with greater than 90 percent accuracy. Another 20 olefins have been detected in various samples. This presentation will discuss the research, analytical parameters such as precision, detection limits, method dynamic range and accuracy, and the results from sample data.
