PROS:- Capture process after boiler simplified- Little penalty associated with capture itself
CONS:- Energy penalty and cost required for ASU
- Additional equip required for CO2 purity- No partial capture configuration possible
PROS:- Process proven in chemical industry- Adaptable to new build, existing retros
- Adaptable to other emitters (steel, cement)- Partial capture configuration possible
CONS:- Energy penalty for capture
- Equipments tend to be larger than other techs
PROS:- Capture equipments smaller (high pressure)- Capture energy penalty smaller
CONS:- Energy penalty and cost required for ASU
- IGCC lacks operational flexibility of CC- Only new build application- No partial capture configuration possible
