Precipitated Calcium Carbonate
The precipitated calcium carbonate production process consists of decarbonating limestone, which separates the CaO (calcium oxide) and CO 2 (carbon dioxide). Precipitated calcium carbonate is produced by slaking high-calcium quicklime to create a calcium hydroxide lime slurry, (Ca(OH) 2 ), that is then combined with captured carbon dioxide (CO 2 ).

Lime Production Process and Required Equipment
Grain size of limestone 1 In the process of calcination, the granularity of the raw limestone affects the whole process a lot. Since the separation of CO2 proceeds slowly from the surface of the limestone to the inside, the calcination of large particle size is more difficult than that of small ones, and it takes a longer time.

Limestone (calcite, CaCO3) is an abundant and cost-effective source of calcium oxide (CaO) for cement and lime production. However, the thermochemical decomposition of limestone (∼800 °C, 1 bar) to produce lime (CaO) results in substantial carbon dioxide (CO2(g)) emissions and energy use, i.e., ∼1 tonne [t] of CO2 and ∼1.4 MWh per t of CaO produced. Here, we describe …
