A brief description of the project:

Particles, oxygen and strong-acid gases (eg, SOx and NOx) are continuing to pose challenges for large-scale post-combustion capture (PCC) of CO2 from coal-fired power stations. Other industries including cement kilns and iron smelters also inherently produce CO2. A carbon-constrained economic environment may require these CO2 emissions to be capture for reuse or storage. This project aims to predict the challenges that will be faced if amine-based acid-gas scrubbing is applied to a range of industrial flue gases. This project could include deep characterisation of particles sampled from typical flue gases and/or laboratory-based experiment to determine the likely impact of typical components.

Available resources

• Iso-kinetically sampled fly ash from local power stations
• Fly ash derived deposits from local PCC pilot plants
• ICPMS, SEM with EDS
• XRD and advanced sample preparation equipment in collaboration with the Mt Helen campus.

Potential industrial impact: reduced risk for translation of PCC technology from fossil-fuel fired power stations to other industrial sources of CO₂
Technology Readiness Level 5. PCC has been demonstrated at scale on coal-fired power stations but not other industrial sources.
