CO2 capture in cement plants by "Tail-End" Calcium Looping process

In this work the integration of the Calcium-Looping (CaL) process, used as a post-combustion CO 2 capture system, into a cement kiln was analyzed by means of process simulations. The results show that capture efficiencies of about 90% can be achieved with operating conditions of CaL reactors similar to those for power generation applications.
