Qatrana - Production Process

During this process, the emitted gases – which include CO2 as a result of the calcinations process – are cooled down from 1,050°C to 350°C, to be used afterwards to dry out the wet raw materials during the grinding process. Calcined raw materials are fed to the rotary kiln where they are burnt at 1,450°C to produce the main cement constituent “Clinker”.

Calcination - Wikipedia

In limestone calcination, a decomposition process that occurs at 900 to 1050ºC, the chemical reaction is CaCO 3 (s) → CaO(s) + CO 2 (g). Today, this reaction largely occurs in a cement kiln.. The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K ...
