A CO₂ flow rig has been designed and constructed at the School of GeoSciences, University of Edinburgh. The system is designed to load a sample loop with a desired gas mixture, which at a given time, can be released into a feeder stream as a pulse through the flow cell.
The flow cell is designed to contain a 36cm diameter core of rock. The core is encased upstream and downstream by gas dispersion plates to allow unobstructed gas flow. Real-time analysis of the arrival peaks of the gases downstream is recorded using a Quadrupole Mass Spectrometer (QMS).
Currently used for PhD: The Role of Noble Gases as Tracers for CO₂ Storage - Investigate how noble gases could be used as effective early warning tracers of CO₂ migration in engineered CO₂ storage sites.
Also used for EPSRC project: Fingerprinting captured CO₂ using natural tracers: Determining CO₂ fate and proving ownership (EP/K036033/1). See more details on this project.
