Post-combustion capture refers to the removal of carbon dioxide (CO2) from a power station flue gas prior to its compression, transportation and storage in suitable geological formations, as part of carbon capture and storage.
A number of different techniques are applicable, almost all of which are adaptations of acid gas removal processes used in the chemical and petrochemical industries.
Many of these techniques existed before World War II and, consequently, post-combustion capture is the most developed of the various carbon-capture methodologies.
Pilot or full-scale tests using actual flue gases and solvents may be performed.
The ANICA project focuses on developing a novel indirectly heated carbonate lopping process for lowering the energy penalty and CO2 avoidance costs for CO2 capture from lime and cement plants.
