DBD-Corona Discharge for Degradation of Toxic Gases

Abstract

The non-thermal plasma technology is a promising technique to treat SO2 and NOx.Chemical radicals produced with this technology can remove several pollutants at atmospheric pressure in a very short period of time simultaneously. Both theoretical and experimental study on SO2 and NOx removal, by a dielectric barrier discharge (DBD) with corona effect, is presented.

Non-thermal plasma for exhaust gases treatment

“…From simulations performed in a previous work [13], the CO 2 treatment is strongly influenced by water and obtains mostly formic acid. Therefore, an activated carbon filter at the plasma reactor outlet is recommended.…”

“…3) Ability to work at atmospheric pressure; 4) Non-thermal plasma temperature at room temperature [12,13]; 5) Ability of the plasma to sulfur compounds, particulate matter, NO x , and VOC.…”

Potential of electric discharge plasma methods in abatement of volatile organic compounds originating from the food industry

“…DBD is not an energy efficient form of plasma treatment (Marotta et al, 2007;Schiorlin et al, 2009): it is used only for convenient modelling and the production of stable and reproducible plasma conditions, i.e., it is appropriate only for the research purposes in the absence of other ways of achieving stable discharge conditions (Pacheco-Pacheco et al, 2007). Schiorlin et al (2009) noted that corona discharge between plain electrodes exceeds DBD in its efficiency by orders of magnitude.…”
