A process of manufacturing cement clinker is provided in which a clean supply of CO 2 gas may be captured. The process also involves using an open loop conversion of CaOMgO from a calciner to capture CO 2 from combustion flue gases thereby forming CaCO 3 CaMgCO 3 2 . The CaCO 3 CaMgCO 3 2 is then returned to the calciner where CO 2 gas is evolved.
Jun 09, 2020 Cement production is currently the largest single industrial emitter of CO2, accounting for 8 2.8 Gtonsy of global CO2 emissions. Deep decarbonization of cement manufacturing will require remediation of both the CO2 emissions due to the decomposition of CaCO3 to CaO and that due to combustion of fossil fuels primarily coal in calcining 900 C and sintering 1,450 C. Here ...
