| Abstract: | This study investigates the feasibility of using nonthermal plasma produced in a dielectric barrier discharge reactor to destroy 1,1,1-trichloroethane (TCA) in a stream of air. The effects of various operating parameters on the destruction and removal efficiency (DRE) of TCA were examined. The experiments indicated that the water vapor concentration greatly influenced the destruction of TCA and the relative amount of oxidation by-products. DRE as high as 99.9% could be achieved at very low relative humidity (RH) conditions. Analysis of the CO/CO2 concentrations in the reactor effluent indicated a decrease in the amount of CO generated as the RH was increased. The lowest CO/CO2 ratio, 1:3, was observed at 88% RH. The estimated cost and energy requirement for operation were also determined. The calculated energy density values (β) varied with respect to the RH, and ranged from 1,478 to 3,010 J/L over a RH range of 0–88%. |
