Magnesium Oxide For Flue Gas Desulfurization Magnesium Oxide for Flue Gas Desulfurization The powder is calcined in tunnel kilns using the magnesite selected from floation as raw material.It possesses high activity and desulfurizes gas with high efficiency. Flue gas desulfurization technology is mainly used absorbent or adsorbent to various alkaline trapping of sulfur dioxide in flue gas and converted into a more stable and easy to mechanicalseparation ofsulfur compounds orsulfur,so asto achieve the purpose of desulfurization. Flue gas desulfurization is a chemical process to remove sulfur oxides from the flue gas at coal-burning powerplants. The broadly used term " lime " connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. As the flue gas comes in contact with the slurry of calcium salts, sulfur dioxide (SO 2) reacts with the calcium to form hydrous calcium sulfate (CaSO 4 2H 2 O, gypsum). http://www.dakotagas.com http://www.basinelectric.com 2 In addition, students The absorbents were examined and compared for its micro-structural properties. Formation of product layers in solid-gas reactions for removal of acid gases. 10. CaO + SO 2 CaSO 3 This … (1) S IV SO 2. Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature. Chemical Equation: CaO (s) + SO 2 (g) → CaSO 3 (s) 2CaSO 3 (s) + O 2 (g) → 2CaSO 4 (s) An experimental study has been performed of the reactions occurring when the reactive particles of calcium oxide are exposed to sulfur dioxide bearing flue gas. The process uses a base, normally calcium hydroxide (Ca(OH) 2), to convert the SO 2 into calcium sulfite: Ca(OH) 2 + SO 2 → Ca SO 3 + CO 2 Many ... (calcium carbonate, CaCO 3), lime (calcium oxide, CaO), or ammonia (NH 3). This paper discusses the development of such a highly reactive calcium-base absorbent. There is a considerable range of practical work that can be carried out. OSTI.GOV Journal Article: Flue gas desulfurization experiments. Modelling of the kinetics of sulphation of CaO particles under CaL reactor conditions. This is a basic oxide which reacts with the sulfur dioxide forming calcium sulfite, an ionic solid which is easily removed as a white powder. The SO 2 is absorbed in the scrubber slurry and forms insoluble magnesium sulfite (MgSO 3) as in the equation below.
