temperature for calcination of dolomite

Effect of dolomite decomposition under CO2 …

the mechanism of dolomite decomposition under CO2 is responsible for enhancing the kinetics of calcination and reactivity of dolomitic CaO [21, 32]. Thus, dolomite decomposes directly into MgO and CaO at a temperature about 700ºC regardless of the CO2 partial pressure in the calcination environment.

What is the difference between dolomite and calcined dolomite?

There is an endothermic heat of calcination that you will need to factor into your heat and material balance calculations. In addition calcined dolomite is friable. When it calcines it usually results in very fine particle size distribution. For sulfur capture limestone is a more effective sorbent compared to dolomite.

Calcination of Limestone |

Calcination of Limestone . Calcination or calcining is a thermal treatment process to bring about a thermal decomposition. The process takes place below the melting point of the product. The name calcination is derived from the Latin word 'Calcinare' which mean to burn lime. Limestone is a naturally occurring mineral.
