Abstract. A substantial amount of CO2 is released into the atmosphere from the process of the high-temperature decomposition of limestone to produce lime. However, during the lifecycle of lime production, the alkaline components of lime will continuously absorb CO2 from the atmosphere during use and waste disposal. Here, we adopt an analytical model describing the …

The PCC production process starts with the decarbonisation of limestone (CaCO3) in a kiln, from which lime (CaO) and fumes (CO2) are obtained. The lime is then transformed into a slurry of lime hydroxide in excess of water (Ca(OH)2 + nH2O ) in an exothermic process, during which it is purified of the heaviest impurities.
