Process integration study of tail-end Ca-Looping process ...

In this work, the integration of Calcium looping (CaL) process into a cement plant for post-combustion CO 2 capture is assessed via process simulations. In the proposed scheme, the carbonator of the CaL process is used as an end-of-pipe unit to capture the CO 2 from the cement kiln gas.. From the results obtained, it is demonstrated that CO 2 capture efficiencies of the order of 90% are ...
