Effect of Carbonation in Removal of Chloride from Municipal Solid Waste Incineration Bottom Ash
Most of chloride in municipal solid waste incineration bottom ash are easily soluble in water. As a reason of that, bottom ash limited its use as a road materials and cement contrete as well as landfill. Thus, the characteristic of chloride in bottom ash was investigated, though the distribution of chloride from based on particle size, characteristic of friedel's salt(3CaO•Al2O3• CaCl2•10H2O) in bottom ash and the removal of friedel's salt via caibonation process. As a result, the content of chloride was increased with the smaller particle size, especially friedel's salt too. The soluble chloride like KCl, NaCl in bottom ash was possible to be removed by washing process, reversely friedel's salt (insoluble) was difficult. But friedel's salt could be removed via carbonation process because that has difficulties of preventing progressive carbonation and in controlling the activity of CO2.
