The removal of Polycyclic aromatic hydrocarbons (PAH's) and soot particles from flue gas was studied using a gliding arc discharge reactor, and the flue gas was emitted from the polyethylene (PE) or polyvinyl chloride (PVC) combustion in a laboratory-scale drop tube furnace. The removal efficiencies have ranged from 70.3% up to 74.4%. The maximum removal efficiency of soot particles was up to 89.3%. Experimental results show that the technique can successfully remove PAH's and soot particles from flue gas, a possible mechanism is proposed to explain the experimental observations.
