A series of experiments were carried out to evaluate the simultaneous NO_x and SO_x removal using the plasma-chemical hybrid process and to quantify all the reaction byproducts such as N_2O and CO. The oxidation from NO to NO_2 without decreasing NO_x concentration and with least power consumption is the key for obtaining the optimum reactor operating condition. The produced NO_2 was totally converted to N_2 and Na_2SO_4 with Na_2SO_3 or Na_2S by the chemical reactor, while NaOH was used to neutralize H_2SO_3 and H_2SO_4 in the solution. The final products is water soluble and nontoxic Na_2SO_4. The NO_2 reduction was more effective for Na_2S than Na_2SO_3 but 2 ppm of H_2S was produced. The hybrid process showed nearly 100% NO_x and SO_x simultaneous removal with less than 11 ppm of N_2O and CO, and the power consumption using the pulse plasma reactor was less than 1/4 using the packed-bed plasma reactor.
