Post-combustion CO2 Capture System
CO2 removal methods are newer and less prevalent and are being studied.
This methods is more like a damage control method given that it is implemented after CO2 generation.
- The CO2 is removed after combustion of the fossil fuel
- This is the scheme that would be applied to fossil fuel burning power plants
- CO2 is captured from flue gases at power stations or other large point sources
- The Technology is well understood and is currently used in other industrial applications
Absorption process (Amine based) technology is widely used for post combustion CO2 separation. Its advantages are:
- High Efficiency (CO2 99.9%)
- Low Energy use and cost
Other Emerging technologies for post combustion CO2 separation are:
- Member based
- Solid Sorbents
