  • Illinois is experiencing increased demand for high-calcium limestone for flue-gas desulfurization High-calcium (CaCO 3 ) limestone is not widely present in Illinois, however, and most limestone quarries consist of multiple layers or ledges whose CaCO 3 content and quality vary significantlyThe desulfurization regulations with different proportions and concentrations of the compound sulfur sorbents (CaCO 3 and fly ash) were studied Results show that: when Ca/S mole ratio is 1024, desulfurization rate of the compound sulfur sorbents is higher than that of CaCO 3 sorbents.

    Figure 6 summarizes the desulfurization efficiency of PFBC which is definitely influenced by the coal to be combusted in the boiler in addition to Ca/S rate Nanton coal definitely lowered the desulfurization efficiency Desulfurization efficiency or SO2 concentration in flue gas was governed in principle by the reaction of CaCO3(CaO) and SO2 .The most commonly used material for flue gas desulfurization (FGD) is limestone due to its availability and price Limestone is mainly made up of calcite (CaCO 3) which, although is alkaline in nature, is not reactive enough to remove a desirable amount of sulfur dioxide from flue gas Therefore, limestone is usually calcined to quicklime (CaO).
