Process for the purification of flue gas

摘要: The invention relates to a process for the purification of flue gas which results from combustion wastes and contains both solids most wide ranging composition also pollutant gases heavy metals in gaseous form, chief solid fractions are removed separation plant collected as fly ash is scrubbed purpose binding remaining fractions, particular slag. object offer not only metal pollutants but primarily present soluble form slag can be eliminated compact possible process, where at same time good HCl, SO2, NOx achieved or even improved. All other residues capable being recycled. solution lies that remainder bound isolated by weakly acid after treatment.
