Pre Combustion Capture

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
