Steam calcination of lime for CO2 capture
Calcination is also used to produce titanium, alumina, and cement. The calcination of limestone typically occurs at a temperature in the range of 800 ºC - 950 ºC [4] and is shown in Eq. 1. (1) Ca CO 3 (s) → CaO (s) + CO 2 (g), ∆ h ¯ 298 K 0 = 178 kJ / mol. The energy for the lime production process is dominated by the highly endothermic ...
