| Scope and method of study. The purpose of this study was to determine the feasibility of a Single Tube Single Dielectric Barrier Discharge (DBD) Plasma Reactor for destruction of toluene in the air phase and to find beta, a scale up parameter. The chief area of interest was the relationships between energy density and destruction efficiency. A number of process variables were examined including secondary voltage, frequency, flow rate and energy density.; Findings and conclusions. Removal efficiencies for toluene in the range of 85--96.9% were observed at relative humidity of 30--45%. Increasing energy density increased the destruction efficiency at a constant inlet concentration and relative humidity. Also, a carbon balance of more than 85% was obtained for toluene during destruction testing. The calculated beta value for toluene was 1233 J/L and this value is higher than the literature value of 99 J/L. |
