The Relation of Limestone Origin and its Reactivity to the Preparation of Desulphurization Agents

Abstract:

Limestone is used in the flue gas desulphurization process due to its ability to form sulfur compounds. Different qualities of limestone absorbents can be used in the process and it is therefore important to measure the reactivity of these materials. A limestone with a 90 to 95% of calcium carbonate is used to prepare limestone slurry for the flue gas desulphurization. It is very important to explore the different properties of the raw material for a better understanding of the desulphurization process and also the impact on the economic aspect of the process [1-3]. This article presents a study about limestones reactivity, which is measured by the Bischof-Uhde method. At first the study monitors the impact of the milling of set of Czech limestones on their reactivity and furthermore deals with the influence of the genesis and porosity of the set of world limestones also on the reactivity of limestones in the desulphurization process.
