Caco3 Flowsheet Factory
Process integration of a Ca-looping carbon capture process …
Fresh CaCO3 is added to maintain reactivity in the carbonator, while the purged sorbents are utilised as a cement kiln feed. The detailed carbonator model has been implemented using Matlab and incorporated into Unisim to provide a full flowsheet simulation for an exemplary dry-feed cement plant as a user-defined operation.

Limestone Flotation Circuit
Selection of the flowsheet was governed by two factors established in the test work; differential grinding and utilization of tailing. As outlined before, differential grinding between the comparatively hard chert and the softer limestone resulted in upgrading of the CaCO3 content of the slimes. The tests indicated that a milling circuit ...
