Broadcasting Oil and Gas Production Related Emissions in Real-Time and Providing Near-Real Time Source Attribution Using a Mobile Laboratory
A mobile laboratory was constructed utilizing a Ford E-350 passenger van. Named the Mobile Acquisition of Real-Time Concentrations (MARC), the van houses a Proton Transfer Reaction Mass Spectrometer (PTR-MS) to measure important hazardous air toxics in real-time. In combination with meteorological and GPS instrumentation, MARC can provide immediate information about the current air quality. The data is also transferred to an off-site database that in turn broadcasts the information to a website providing real-time information to off-site personnel.
The information on the database is also input into an inverse model, which is used for source attribution. The model is a 3D micro-scale Eulerian forward and adjoint air quality model that uses a 3D digital model of the facility of interest and the Quick Urban and Industrial Complex (QUIC) wind model output along with the real-time observations of MARC to determine the time, place, and quantity of emissions. MARC has been deployed to quantify oil and gas production-related emissions, results from which will be shown to demonstrate the capability to broadcast data in real-time and the potential to provide near real-time source attribution.
