energy calculations for calcination of gypsum

Calcination - Wikipedia

For example, in limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g) 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, or 848 °C.

Grinding and drying, gypsum calcination - Scheuch GmbH

Whether the process involves grinding, drying or calcination, the aim in every case is to eliminate water from the raw material. In state-of-the-art technology, this is accomplished using an all-in-one unit. At the end of the grinding product calcination process, the exhaust air that is produced is extracted and separated in a filter.

Energy analysis of CaCO3 calcination with CO2 capture ...

Analysis showed that, although H 2 O (steam) cycle calcination had calcination energy more about 3.6% than CO 2 cycle due to water evaporation latent heat loss, however, the calcination energy per active CaO was lowest for H 2 O (steam) cycle. © 2010 Elsevier Ltd.

The highest environmental influence could be assigned to the calcination of gypsum in the kiln (more than 50%), for both natural gypsum and FGD gypsum as raw materials. Burning of a substantial amount of natural gas during this process can be perceived as a significant factor generating greenhouse gas emissions and damaging the ozone layer.
