This work analyzes the capacity of a novel CaCO3 precalcination method to reduce the CO2 emissions from an industrial cement plant by means of CO2 capture and storage. The precalciner consists of a circulating fluidized bed combustor (CFBC) operating at about 1050 degrees C connected with a fluidized-bed calcine; A stream of CaO at about 940 degrees C coming from the CFBC transfers the heat required for calcination to the fluidized-bed calciner. The thermal integration between the main units in the, capture system (the CFBC, the calcine; the CO2 compressor, and a reference cement plant) was fully analyzed using Aspen HYSYS. Optimum management of the heat fluxes between the units is essential to minimize the heat requirements for the CO2 capture system. A subcritical steam cycle that can be integrated into the new cement plant is proposed to obtain the energy necessary to drive the CO2 compressor and generate electricity, which can either be used in the cement plant itself or be exported. It is shown that, with this level of integration, it is possible to avoid about 38% of the CO2 emissions produced by the cement manufacturing process. Furthermore, an estimation of the additional cost of implementing the precalcination system in the cement plant shows that a competitive cost of about $12 per ton of CO2 avoided can be achieved.
