Experimental Investigation on Styrene Emission with a 1000m3/h Plasma System

摘要

This paper reports experimental investigations on plasma-induced styrene emission abatement in air at room temperature (24±2°C) and pressure. Tests were performed with a 1000 m3/h plasma system under DC corona discharge. It is observed that styrene destruction in DC glow discharge is negligible in contrast to streamer corona. When relative humidity (RH) is in the range of 30%-80%, the energy consumption for styrene decomposition rises with RH value. The energy coefficient β value becomes larger with increasing either RH or the initial styrene concentration for RH in 30%-80% and the concentrations within 90 ppm-1000 ppm,respectively, With regards to those dependence sensitivity, the lower the concentration, the more sensitive to the RH value. Under optimal condition (100 ppm initial concentration, 35 %RH), the β value is 18.73 J/L.
