Hydrocarbon emissions from oil and gas facilities are due to both routine and non-routine sources and can have emission rates that range from g/h to Mg/h or more. Large, non-routine emission events that are due to malfunctions or process upsets can constitute a large fraction of total emissions, and their frequency, durations and magnitudes have primarily been established based on observational data. To develop effective prevention and mitigation strategies for these events, it is necessary to understand the probabilities of the failure modes that lead to emission events. Process safety analyses have been used extensively to predict failure probabilities, and to develop prevention and mitigation strategies for events that compromise safety. The same analysis frameworks can be applied to large emission events. The analyses can be applied at both site and supply chain scales. This presentation will describe the analysis framework and will apply the framework to case studies of site level emission events and emission events caused by supply chain disruptions

Dr. David Allen (allen@che.utexas.edu) is the Gertz Regents Professor of Chemical Engineering, the Director of the Center for Energy and Environmental Resources, and the co-Director of the Energy Emissions Modeling and Data Lab at the University of Texas at Austin. Dr. Allen has been a lead investigator for multiple air quality measurement studies, including studies that made some of the first measurements of methane emissions from unconventional oil and gas production. He has served on a variety of governmental advisory panels and from 2012 to 2015 chaired the U.S. Environmental Protection Agency’s Science Advisory Board (SAB). He currently serves on the SAB. In 2017, he was elected to the US National Academy of Engineering.
