|Abstract:||In this paper, a quantitative analysis and comparison of CO2 capture technologies which could be applied to the cement manufacturing process is performed. Process concepts already used by other industries and currently explored by the power sector, post combustion absorptive capture and oxy-combustion options and the novel calcium looping post combustion capture technology, are compared, in terms of energy efficiency, CO2 footprint, CO2 capture efficiency, raw material consumption and product quality. This has been achieved through the modelling of the integration of these process concepts with a reference cement plant. The results show that oxy-combustion and post combustion absorptive capture technologies perform better and have a particular advantage over chemical looping in terms of energy consumption. However, chemical looping offers a high degree of integration with an existing cement plant, without the need of major modifications to kiln operations, which is the case for oxy-combustion. These results contribute to the identification of the most suitable CO2 reducing strategy for the cement industry.|
