“…The detoxification of air pollution caused by volatile organic compounds (VOCs, such as TCE, TCA, toluene, and xylene), acid and greenhouse gases (such as SO x , NO x , HCl, CO x , N x O y , and PFCs), or ozone depletion substances (Freon or Halon) may be assisted by plasma . Generally, a number of pollutants are present in waste air, and plasma decomposes different hazardous air pollutants at the same time .

Cold physical plasmas ignited a technological spark in industry, biotechnology, and medicine. Especially the field of hygiene benefited of the plasma's exceptional activity against pathogenic microorganisms. Together with plasma-based surface functionalization, these qualities are highly relevant in a variety of processes in health care, such as the decontamination or sterilization of medical devices, food, packaging materials, waste water, or indoor air. In medicine, plasma has proven to show promising antiseptic results on skin and mucosal membranes in infection-related diseases in dermatology and dentistry. This comprehensive review will discuss the current applications of cold plasma in the fields of hygiene, and will provide a promising outlook on many applications yet to come.

“…It can be seen that the sum of the number densities of HSO 3 and H 2 SO 4 is several orders of magnitude larger than that of SO 3 , so the oxidation by OH is the main path of SO 2 removal. The reduction reaction with N is another important removal route for NO in NTP besides oxidation by O, O 3 , and OH [28], as shown in R81. The variable η is defined as the percentage of NO removed by oxidation in the total amount of NO removed, as shown in Equation (25):…”

Non-thermal plasma (NTP) technologies can be used to treat a variety of gaseous pollutants, and extensive research has been carried out worldwide because of its high purification efficiency, low dependence on temperature, and other advantages. NO and SO2 are the main gaseous pollutants in coal-fired flue gas. The plasma dynamics for desulfurization and denitrification is a hot topic in the field of NTP pollutant control technologies. In this paper, a one-dimensional fluid model for the simultaneous desulfurization and denitrification of flue gas by negative direct current (DC) corona discharge was established based on the traditional zero-dimensional chemical kinetic model. The simplified wire-cylindrical electrodes configuration and numerical simulation conditions are similar to the working process of electrostatic precipitators. The results obtained by the finite element method show that the removal efficiency of NO and SO2 is remarkable in the region with a radius of less than one centimeter around the high-voltage electrode, and the effective purification area expands with the increase of the discharge voltage. There are different removal pathways for NO at different positions in the removal region, while the removal of SO2 is mainly dependent on the oxidation by OH.

“…During the NTP process, many active radicals, such as O, OH and O3 are generated. These oxidize gaseous pollutants such as volatile organic compound (VOC), NOx and particulate matter (PM) at room temperature and atmosphere pressure [10]. NTP holds the advantages high oxidation efficiency, low floor area, no chemical addition, low initial cost, low temperature and at atmospheric pressure, and energy consumption [11] Non-thermal plasma (NTP) as a useful method for NOx removal has been investigated in many years.…”

Nowadays, global warming is the main environmental problems all over the world. The air pollutants mainly from the burning of fossil fuels and coal in power plants, transportation, and automobiles. There are release major point emission of the atmosphere. The nitrogen oxides are the most relevant for air pollution that contribute to the formation of photochemical smog and acid rain. Numerous methods have been studied to eliminate the nitrogen oxides such as the use low-nitrogen fuels technology, the selective catalytic reduction (SCR), wet scrubbing. The aim of this research is investigated non-thermal plasma (NTP) techniques offer an innovation to eliminate both nitrogen oxide (NOx) and soot emissions from combustion. This study is used to selectively transfer input electrical energy to electrons without expending this in heating the entire gas flow which creates free radicals in the flue gases. The simulated flue gas from combustion process is applied to the system. The results showed that the prototype of nonthermal plasma system is shown the highly efficient of NOx removal was achieved. However, the optimised of NTP operating conditions are required to enhance the NOx reduction activities.
