CO2 Capture by Calcium Looping at Relevant Conditions for Cement Plants: Experimental Testing in a 30 kWth Pilot Plant
Calcium looping technology has a high potential for capturing
CO2 in cement plants as the CaO-rich 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 (i.e., a higher carbonator CO2 load, a more active
sorbent, smaller particle sizes). This work analyzes the impact of some of the
new CaL operating conditions on the performance of the carbonator in a
retrofitted 30 kWth testing facility as there is little experimental information
available nowadays. A wide range of sorbent activities has been tested,
including those corresponding to very large makeup flows of limestone that
would be characteristic of CaL applications in cement plants. The results have
been interpreted using a basic reactor carbonator model that required little
modification of previous versions developed for power plants.This project has received funding from the European Union鈥檚
