Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900°C. To ensure a high level of purity, the calcination process is carried out using natural gas. After the calcined lime has been slaked with water, the resulting milk of lime is purified and carbonated with the carbon dioxide ...

NUMERICAL MODELLING OF CALCINATION OF …
Lime is produced in lime kilns, where limestone is heated until the limestone is converted to lime and carbon dioxide (CO 2). This thermal treatment of limestone is called calcination, and can be described as CaCO 3 → CaO + CO 2. Calcination is a highly endothermic reaction, causing the energy requirement to be high for the process.
