| Abstract: | The electron beam (EB) technology has been investigated as a one-stage multi-component purification technology. The initial concentrations of SO2, NOx, and 16 polycyclic aromatic hydrocarbons (PAH) in flue gas have been reduced simultaneously by over 60%, 50%, and 20%, respectively, in flue gas at the dose of 8 kGy. Determined PAH distribution in the by-product has shown negligible role of adsorption in PAH removal. PAH-based overall toxicity of flue gas decreased remarkably in the range of 30–80% under EB irradiation. |
