Dr. Court D. Sandau to present at 11th Multidimensional Gas Chromatography Workshop
Dr. Court D. Sandau will present environmental case studies using GCxGC-TOFMS at the 11th Multidimensional Chromatography Workshop in Honolulu, Hawaii, January 5-7, 2020.
Dr. Sandau will present Use of GCxGC-TOFMS in litigious mixed condensate plumes: Environmental forensics case studies, coauthored with Dr. Kates.
Condensate is a complex mixture of light petroleum hydrocarbons that is primarily used to dilute heavy crude oil for transport through pipelines. Many heavy oils, especially bitumen from the oil sands in northern Alberta, use condensate to dilute the bitumen to allow the product to flow to refineries where the oil can be upgraded. This is where the term ‘Dilbit’ was derived. Condensate is valuable; it can be recycled and reused and is frequently transported through the North American pipeline network. Pipelines gather at pipeline terminals where there can be multiple sources and multiple suppliers of different types of condensates. When leaks occur at these terminals, it can be difficult to determine the exact source of the leak, especially if pipeline integrity seems intact. GCxGC-TOFMS is the ideal technique to examine mixed condensate plumes as it allows the comprehensive fingerprint of the condensate to be determined and simultaneously provides substantial data to evaluate weathering and plume movement. In addition, the amount of chemicals measured using GCxGC-TOFMS can allow source apportionment of multiple sources so that allocation of the cleanup responsibility can be made. This presentation will discuss the use of GCxGC-TOFMS in legal case studies involving mixed condensate plumes. Real scenarios of condensate plumes will be presented showing how GCxGC-TOFMS data clarified the results compared to conventional analysis. This presentation will also cover the hurdles of using a novel and unconventional technique for litigation proceedings.
