1. Introduction. The process emissions of lime production, i.e. the CO 2 released during limestone calcination excluding that released from the combustion of fossil fuels, are estimated to account for about 1% of the global anthropogenic CO 2 emissions excluding those associated to land use change [Citation 1].Anthropogenic CO 2 emissions are the …

Calcination is the main process of clinker production, calcining calcium carbonate (CaCO 3) at about 900 °C to form calcium oxide, CaO, lime, and the release of carbon dioxide gas (CO 2). In the next step of the so-called clinker treatment, calcium oxide (CaO) is exposed to temperatures of 1400 °C to 1500 °C together with silica (SiO 2 ...

production costs to a minimum. In the majority of cases, a very major production cost will be the fuel used. Thus, the efficiency of the burning process (as opposed to the whole process of production which will involve labour costs etc.) is judged by how much fuel it takes to produce a quantity of quicklime.

The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes of CO 2 arising …

They form long-term, permanent bonds that drastically improve the bearing capacity of a soil. Co-products of the lime manufacturing process can be valuable as clay content decreases in the soil. These materials bring pozzolanic properties, from the lime manufacturing process, to the soil mix where the reactions can form high-strength bonds.
