Abstract:

Sulfuric anhydride is one of the most voluminous technological emissions. The possibility of high-temperature SO 2 oxidations without catalyst in presence of calcium-bearing filling materials (CaO, Ca(OH) 2 and CaCO 3) with obtaining of binding material on the basis of waterless calcium sulfate is studied. Due to application package HSC-4 the thermodynamic analysis of the specified interactions is made and following conclusions are drawn: 1) Reactions are feasible in the all range of investigated temperatures (400-1000 °C); 2) The best results should be expected at use of CaO; 3) The heat of reaction does possible autogenous behavior of process. The researches have shown: 1) Practical possibility of the process; 2) SO 2 oxidation without the catalyst is feasible in presence of CaO, Ca(OH) 2 and CaCO 3; 3) The optimum temperature range is 600-800 °C; 4) The content of waterless calcium sulfate in a product reaches 48% that makes it possible to use as the binding material; 5) At excess of CaO the degree of SO 2 collection is nearer to 100%.
