“…A non-thermal plasma (NTP) process, using a dielectric barrier discharge (DBD), has been introduced as a promising technology for NOx and particulate matter removal [1,[5][6][7]. It has great potential for emission treatment since it can operate stably at atmospheric pressure and even at low temperature [8].…”

In this paper, a comprehensive study of a DBD reactor is conducted to investigate the optimum operating conditions of the reactor for NOx treatment. For each parameter, the objective is to find the maximum NOx removal efficiency with the minimum consumed power. Different effective parameters of the reactor i.e. electrode length and diameter, electrode and dielectric materials as well as parameters of power generator, i.e. voltage and frequency, are investigated. The results show that for this configuration, the electrode with 20 cm length and 10 mm diameter has the best performance. Aluminum as the inside electrode material and quartz as the dielectric material are selected. Furthermore, the optimum value for the pulse frequency is 16.6 kHz. For the mentioned optimum conditions, the NOx removal efficiency achieved is equal to almost 82% at the input power of 486 W. Furthermore, the highest achieved NOx removal is almost 92% at the input power of 864 W. The results of this paper can be used to reduce the energy consumption of NTP systems to acceptable levels.

“…ESP is the device of choice for controlling particle emissions of many industrial applications. 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].…”

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.

“…In atmospheric air, DBDs are able, via ionization, to produce chemically active species such as oxygen and hydroxyl radicals. These reactive species are useful in various applications, such as surface modification [2], [3], flue gas [4] and waste water treatment [5], assisting in combustion [6], [7] and for fuel synthesis [1]. The production of these reactive species is affected by the properties of the plasma, such as the electron density, n e which is the number of electrons per unit volume produced by the discharge, and the electron temperature, T e which gives the average energy of the electrons produced by the discharge.…”

Abstract-An atmospheric air non-thermal plasma (NTP) device is characterized in relation to ozone production. The electron density, n e , electron temperature, T e and ozone concentration are measured for three dielectric barrier discharge (DBD) geometries, i.e., ten tubes of 10 mm outer diameter (OD), six tubes of 25 mm OD, and three tubes of 40 mm OD.n e and T e are deduced using optical emission spectroscopy via the line ratio method and the ozone concentrations are measured by using an ozone meter.n e and ozone concentrations were the highest for the three tube-40 mm configuration, showing a correlation between the number of charged particles and ozone production.
