“…As a very rough estimation, the energy costs for conversion of noxious compounds is about 20 eV/molecule. This corresponds to 0.1 to 1 kg/kWh, a value which is comparable to that obtained in non-thermal plasmas (Hammer, 1999). Gliding arcs ( fig.…”

“…Recently it was shown that the thermal and non-thermal plasmas [3][4][5][6][7][8][9][10][11] have a potential to convert nitrogen oxides in less harmful compounds. Some investigations were carried out to convert N 2 O into NO, NO 2 or N 2 O 4 using the gliding discharge [10,11].…”

Results of using a moderate-power (several hundred Watts) pulsed microwave torch plasma (MTP) to the conversion of atmospheric-pressure nitrous oxide (N 2O) into nitrogen oxides (NO, NO2 and N2O4) are presented. The pulsed regime allowed to decrease the average power used, resulting in a higher value of energy efficiency by about 10 % (reaching several hundred g[N2O]/kWh) at the same efficiency of the decomposition of N 2O (70 ÷ 90 %) as at the continuous operation of MTP. The removal rate increased up to 200 g[N2O]/h. The obtained results suggest the pulsed MTP promising for efficient decomposition of various gaseous pollutants, e.g. fluorocarbons.

“…Ozone (O 3 ) is applied as a disinfectant and oxidant for water treatment, but it also plays a major role for plasma oxidation of NO [57] and particulate matter (PM) [58]. NTPs were utilized for treatment of volatile organic compounds (VOCs) as well as short-and long-chained hydrocarbons [59,60]. Thus, NTPs are promising for exhaust gas treatment for automotive and industrial applications.…”

“…Most of the presented studies on pollutants removal using NTP were conducted on laboratory-scale test benches, many of them using synthetic flue gas [57,59,60,74]. According to these publications, energy consumption and cost of the plasma generation are the main challenges of using NTP for pollutant removal [74].…”

Heat and mass transfer as well as chemical reactions in technical processes can be enhanced by using electric fields. This paper provides an overview of current fundamental and applied research as well as potential technical applications of electric fields in energy and process engineering. This includes electrosprays, technical combustors as well as electrochemical reforming and plasma gasification of waste or biomass. Other emerging fields are plasma technologies for treatment of water, surfaces and gases including flue gases. In particle or aerosol-laden flows, plasmas are used to promote particle nucleation and surface growth for controlled nanomaterial synthesis. Furthermore, non-invasive diagnostics based on electromagnetic fields and electric fluid properties are relevant techniques for online control and optimization of technical processes. Finally, an overview of laser-based techniques is provided for studying electro-hydrodynamic effects, temperature, and species concentrations in plasma and electric-field enhanced processes.
