WhatsAppCO2 Capture by Calcium Looping at Relevant Conditions for ...
Calcium looping technology has a high potential for capturing CO2 in cement plants as the CaOrich purge from the calciner can be used to replace a sizable fraction of the CaCO3 used as feedstock. Integrating the CaL process into the cement plant requires the carbonator reactor to operate under new conditions (, a higher carbonator CO2 load, a more active sorbent, smaller particle sizes).
