Post-combustion capture refers to the removal of ''CO₂'' from power station

flue gas Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produc ...

carbon capture and storage Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia. Usually th ...

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. Calcium looping is a promising second generation post-combustion capture technology in which calcium oxide, often referred to as the ''sorbent'', is used to separate CO₂ from the flue gas. Th
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.
