Industrial experiments on desulfurization of flue gases by pulsed corona induced plasma chemical process

Based on the large amount of data obtained in the laboratory, desulfurization studies of the flue gases on industrial experiment scale by Pulsed corona induced Plasma Chemical Process (PPCP) were accomplished. The flow rates of flue gases were 3000 and 12,000–20,000 Nm3/h. For a 1000–2000 ppm concentration of SO2, the removal rate of SO2 can be more than 80% with the flue gas temperature 70–80°C, water volume ratio 10%, resident time 5–8 s and energy consumption 3–4 Wh/Nm3.
