“…Penetrante et al [33] has analyzed this reaction within oxygen rich atmospheric plasma and deduced a reaction efficiency of 10% at 300 o C, whilst the counter reaction (NO 2 → O + NO) is active at greatly elevated temperatures. In this study evidence for this counter reaction is found in the OES spectra of the arc region, thus helping to confirm the ~1700 o C rotational temperature measurements in this region.…”

Plasma treatments are widely used to activate polymer surfaces prior to adhesive bonding. This study investigates the influence of plasma treatment conditions on the surface activation of a range of polymers using the PlasmaTreat (Open Air) system. In this study the effect of dc pulse plasma cycle time, compressed air flow rate and the plasma jet nozzle to substrate distance on the plasma discharge was examined. The influence that the dc pulse plasma cycle time parameter has on the activation of polypropylene, polystyrene and polycarbonate was also investigated. The level of polymer surface activation was evaluated based on the change in water contact angle after plasma treatment. The polymer surface properties were also monitored using AFM and XPS measurements. The heating effect of the plasma was monitored using both infrared thermographic camera and thermocouple measurements. Plasma diagnostics measurements were obtained using the photo‐diode and optical emission spectroscopy techniques. From this study it was concluded that for the PlasmaTreat system the level of plasma activation was closely correlated with the dc pulsed plasma cycle time, which is a measure of the plasma intensity. For example, the more intense plasma obtained with shorter cycle times gave higher levels of polymer activation. The optimized pulsed plasma cycle times were found to be specific for a given polymer type and related to their thermal properties. The pulsed cycle times were also found to correlate with both the substrate and plasma gas temperatures. magnified image

“…Among others, the pollutants successfully treated with plasma are acid gases such as NO x , [1][2][3][4][5][6][7] SO x , [6][7][8][9][10] and greenhouse gases such as CO x , [11,12]. Despite successful control in a number of industries, the emitted amounts of volatile organic compounds (VOCs) are still substantial.…”

Methanol and dimethyl sulfide are volatile organic compound (VOC) air pollutants that are subject of severe environmental regulations due to their toxicity, environmental persistence and odor. Traditional technologies are often inefficient for their removal, especially in the case of the dilute industrial streams. Non-thermal plasma methods, typically characterized by high removal efficiency, energy yields and good economy, offer possible alternative solutions. The present research employs pulsed corona discharge known for its high selectivity and low energy costs of emission control. This paper provides experimental (Part I) and in a later issue numerical (Part II) data on removal of methanol and dimethyl sulfide from dry and humid air streams. The removal efficiency and the specific energy input are evaluated along with the energy costs required for the removal process. Particular attention is given to the formation of unwanted byproducts such as NO x , CO, and SO 2 .

“…However, it is well known that NO 2 reacts with hydrocarbons on a catalyst surface and is de-oxidized to N 2 . Figure 8 shows the gas composition (FT-IR spectra), which shows the effect of a catalyst only, plasma only, and plasma plus catalyst combination on NO X and hydrocarbons [57]. In this case, propene is used as the hydrocarbon reactant.…”

A review of mainly the past two years is undertaken of the industrial applications of pulsed power. Repetitively operated pulsed power generators with a moderate peak power have been developed for industrial applications. These generators are reliable and have low maintenance. Development of the pulsed power generators helps promote industrial applications of pulsed power for such things as food processing, medical treatment, water treatment, exhaust gas treatment, ozone generation, engine ignition, ion implantation and others. Here, industrial applications of pulsed power are classified by application for biological effects, for pulsed streamer discharges in gases, for pulsed discharges in liquid or liquidmixture, and for material processing.Index Terms -Pulsed power, industrial application, bioelectrics, exhaust gas treatment, discharge in liquid, material processing.
