oxide from dolomite is the calcination route. Calcite and magnesite decompose at different temperatures, a stepwise decomposition permits the selective calcination in which magnesite is completely decomposed without decomposing calcite. Magnesium oxide is then separated physically from the calcined dolomite by sieving or air separation.
Dolomite Calcination Combined with Carbon Gasifiion. The equilibrium composition for the initial mixture of CaMg(CO3)2 + 2C in the temperature range 7001500 K is shown in Figure 2 (for clarity, the reactant dolomite and product lime are not shown). By carrying out the calcination of dolomite in the presence of carbon, the emitted CO2 is . Get Price
The effect of time, temperature, and pressure of carbon dioxide upon three types of dolomite is brought out. Dolomites are either double salts or solid solutions or mixtures of the two. The effect of lime and silica is pointed out. Dissociation, tensile strength, volume change, time of …

17.10.2018· In this research, dolomite ores are used to produce MOS cement at different calcination temperatures and calcination times; the parameters investigated are the rate of loss on ignition, free lime (f-CaO), dihydrate gypsum (CaSO 4 ×2H 2 O) and impact of active magnesium oxide (α-MgO) content exerted on the setting time and compressive strength of the MOS cement.
oxide from dolomite is the calcination route. Calcite and magnesite decompose at different temperatures, a stepwise decomposition permits the selective calcination in which magnesite is completely decomposed without decomposing calcite. Magnesium oxide is then separated physically from the calcined dolomite by sieving or air separation.
The calcination time is critical during the calcination process. It is desirable that the calcination time should be as short as possible. However, enough time must be allowed for heat to transfer to the inside of CaCO3 particles and for carbon dioxide gas to be exhausted from the inside of particles.
Effect of dolomite decomposition under CO2 pubs.rsc. One of the major drawbacks that hinder the industrial competitiveness of the calcium looping (CaL) process for CO 2 capture is the high temperature (∼930950 C) needed in practice to attain full calcination of limestone in a high CO 2 partial pressure environment for short residence times as required.
Performance of Dolomite Calcination in a Bench. Calcination of dolomite involves heating the raw material at sufficient temperature in order to release the carbon dioxide from its carbonate minerals This process is commonly conducted in a rotary kiln There have been a number of calcination studies in a laboratory scale but the study of dolomite calcination in a larger scale is very scarce This ...
residence time inside each zone will enhance thermal efficiency and reduce fuel consumption. The amount of thermal energy that is required in shaft kiln for the chemical reaction of dolomite calcination, accounts for an important part of the energy cost.
