Analysis of the potential of the raw materials and life cycle assessment applied to the mitigation of carbon dioxide in the atmosphere by carbonation processes


Among the proposals to mitigate carbon dioxide (CO2) in the atmosphere by the technology of Carbon Capture and Storage (CCS) and, more recently, by the technology of Carbon Capture, Utilization and Storage (CCUS) have been proved promising. The mineral carbonation process (CM) is one of the more promising CCUS technologies. However, due to the high cost of operation and high consumption of energy and chemicals, it is necessary to optimize the process so that it can be deployed on an industrial scale. The Calcium Looping (Ca-L) process is another promising CCS technology for CO2 capture by the reaction of calcination of the limestone sorbents, followed by the reversible carbonation reaction. The disadvantage of the Ca-L process refers to the deactivation of sorbent due to CO2 capture decay after several calcination/carbonation cycles. The application of Life Cycle Assessment (LCA) in the analysis of environmental performance in biomass power generation is still little discussed in the literature, especially when it involves CCS/CCUS technologies. In this context, the present proposal aims to advance the development of CCS/CCUS technologies by carbonation reactions, using serpentinite and steel slag for CM process and limestone sorbents for Ca-L process, including the LCA application on the environmental performance. The results to be obtained will be unpublished and of interest to basic and applied research, aiming at the industrial application to obtain higher conversions in carbonation processes, cost reduction and efficiency increase and, consequently, mitigation of carbon dioxide in the atmosphere.
