    To provide design guidance for volatile organic compound (VOC) abatement devices, we numerically simulate VOC decomposition in atmospheric-pressure air using direct (in-reactor) and indirect (plasma-injection) nonthermal plasma methods via Microsoft Excel Visual Basic for Applications, and compare predictions with experimental results. Sixteen chemical species, including electrons, are considered for the air plasma with diluted VOC, integrated with a 33-reaction kinetic mechanism to simulate transient species evolutions. The direct-plasma model was calibrated to published toluene (C₆H₅CH₃) decomposition data from a coaxial dielectric-barrier-discharge reactor and then transferred, without further tuning, to predict the performance of the indirect plasma-injection configuration for VOC of allyl disulfide (C₆H₁₀S₂). Across four tubular-channel regions, simulations capture ozone formation and VOC decomposition trends, yielding predicted outlet concentrations as well as other radical components. The experimental VOC removal efficiency (77.5%-83.7%) agrees qualitatively with the calculated data (83.7%-99.9%).

    Nitrogen oxides (NOx) and sulfur oxides (SOx) emitted from thermal power plants are hazardous pollutants causing acid rain and air pollution. To meet the respective emission regulations, NOx is treated using the selective catalytic reduction (SCR) method, while SOx is treated using the lime gypsum method before being discharged via a flue-gas stack. Recently, some local governments and companies have signed environmental protection agreements that impose stricter limits than national emission regulations. Moreover, existing technologies, such as low-NOx burners and SCR, exhibit limitations in achieving further NOx reduction. Therefore, further pollutant reduction measures are required, particularly NOx treatment methods that can be retrofitted into existing flue gas treatment systems in thermal power plants. A plasma-chemical hybrid process (PCHP) offers a promising solution for simultaneous removal of NOx and SOx and can be retrofitted. In this study, laboratory-scale experiments were conducted to evaluate the simultaneous removal of low-concentration NOx and high-concentration SOx using ozone (O3) injection and absorption towers, simulating the integration of PCHP into the absorption tower of flue gas treatment equipment in a coal-fired power plant. The results show that PCHP enables simultaneous removal of low-concentration NOx and high-concentration SO2, although water spray impacts NO oxidation.

    Diesel engines have better fuel economy and emit less CO2 than gasoline engines. However, because their exhaust gas contains large amounts of nitrogen oxides (NOx), particulate matter (PM), and hydrocarbons (HC), aftertreatment is necessary. We use a new plasma aftertreatment method to remove PM in the exhaust gas. Particle concentrations are measured before and after plasma treatment using a scanning mobility particle sizer (SMPS) and a laser particle counter (LPC). The engine load is set to 0%, 24%, 48%, and 72% using electric heaters. The exhaust gas is diluted with N2+O2 mixed gas (O2 concentration 13%), and the mixed gas flow rate is adjusted to 5, 10, and 15 L min−1. The input power of the reactor is adjusted to 100, 200, 300, and 400 W. PM removal performance is measured, and the removal efficiency is 83% or more under all conditions. At flow rates of 5 and 10 L min−1, a removal efficiency of 95% or more is obtained. At a flow rate of 15 L min−1, 48% load, and input power of 100W, a removal efficiency of 95% or more is obtained. At a flow rate of 15 L min−1, the removal efficiency decreases under several conditions. Under these conditions, the residence time is short due to the high flow rate. It is also considered that sufficient removal is not achieved due to the large number of particles before treatment and the low discharge power. The increase in small particles reduces the removal efficiency in the small particle size range. Since previous studies have achieved high removal efficiencies of 67% NOx and 76% HC using equipment and conditions similar to those of this device, we believe that this surface discharge electrostatic reactor can achieve highly efficient simultaneous removal of PM, NOx, and HC.

    In glass bottle manufacturing plants, products are formed by melting raw materials at approximately 1500 °C using heavy oil and liquefied natural gas (LNG) in a melting furnace. The exhaust gas generated during this process contains nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM), which contribute to environmental contamination when released into the atmosphere. Conventional exhaust treatment systems for glass melting furnaces typically include wet or semi-dry desulfurization equipment utilizing sodium hydroxide (NaOH), a compound that readily reacts with sulfur dioxide (SO2), and dust collectors such as electrostatic precipitators or bag filters that primarily collect sodium sulfite (Na2SO3) and sodium sulfate (Na2SO4) produced during the desulfurization process, effectively enabling desulfurization and PM removal. However, they lack an efficient method for NOx removal due to the presence of catalyst poisons, including sticky dust, in the exhaust gas. This study proposes a plasma-chemical hybrid process (PCHP) for the simultaneous removal of NOx and SOx. This process integrates plasma oxidation with chemical reduction and can be incorporated into existing desulfurization reactors. Furthermore, this study applies PCHP to an operational glass melting furnace exhaust gas treatment system, achieving simultaneous removal of PM, NOx, and SO2.

    Nonthermal plasma reduces carbon dioxide to carbon monoxide, which can be converted into fuels and organic compounds, and is used as a raw material for gas synthesis. However, the energy efficiency is currently too low for practical use, and innovative ideas are required. This study proposes a CO2 fuel conversion technology using solid CO2 in a nonthermal plasma reactor. The advantages of using solid CO2 are the suppression of the CO re-oxidation reaction at low temperatures and the improvement in energy efficiency at high CO2 concentrations. In the experiment, the plasma reduction of gaseous and solid CO2 is performed using a dielectric barrier discharge plasma reactor, and the conversion and energy efficiencies are compared. The concentration of generated CO is found to be dependent on the concentration of CO2. When nonthermal plasma is applied to solid CO2, Joule heating causes CO2 sublimation, which reduces gaseous CO2 to CO. The solid CO2 in the plasma reactor increases the impedance and decreases the discharge power. The introduction of solid CO2 upstream of the reactor increases the discharge power and improves the CO conversion efficiency. At a specific energy of 1.8 eV/molecule, the reduction of solid CO2 increases the conversion efficiency from 1.4% to 1.8% and the energy efficiency from 2.3% to 2.7%, compared to the reduction of gaseous CO2.

    To use the continuous combustion of fossil fuels as a sustainable energy source, a low-cost and energy-saving exhaust gas treatment for NOx, SOx, and suspended particulate matter is required. The plasma hybrid exhaust gas treatment technology proposed by the authors is not only a method of plasma treatment, but also a method that combines it with a chemical process, such as chemical solution stabilizer, to clean exhaust gas. This study reports the simulation and application of glass melting furnace exhaust gas treatment as a practical result of the plasma chemical hybrid process (PCHP). In the experiment, higher removal efficiencies of NO, NOx, and SOx (33, 16, and 55%, respectively) were obtained. The energy efficiency of NOx removal by evaluating the electrical power using the cost of NaOH and the power of ozonizers was measured to be 23 g(NO2)/kWh. From comparison, the simulated and experimental temperature distributions and NOx concentration were found to be in good agreements. This indicates that numerical design simulation produces a satisfactory result. PCHP can potentially be the most suitable method for exhaust gas treatment in glass melting furnaces.

    <p>To sustainably reduce carbon dioxide (CO<sub>2</sub>) emissions at ambient temperature and atmospheric pressure, CO<sub>2</sub> is reduced to carbon monoxide (CO) using nonthermal plasma (NTP) flow and a catalyst. In a liquefied natural gas (LNG) gas-turbine combined power generation plant with high power generation efficiency, CO<sub>2</sub> zero-emission can be achieved for the power plant if the energy efficiency of CO<sub>2</sub> reduction by NTP is at least 49%. In this study, CO<sub>2</sub> reduction performance is evaluated for a two-step process using different gas mixtures. First, CO<sub>2</sub> is adsorbed from a gas flow mixture of nitrogen (N<sub>2</sub>) and CO<sub>2</sub> (~10% concentration) by an adsorbent; second, CO<sub>2</sub> is desorbed and concentrated by NTP flow to a higher concentration from 19% to 25% and reduced by N<sub>2</sub> NTP flow and a catalyst under all experimental conditions. γ-alumina, copper, and copper doped alumina are used as catalysts, and the results are compared with those of a previous study where zeolite was used. The energy efficiency increases with the elapsed time and can reach 9−11%. When using copper doped alumina, plasma-catalysis promotes CO<sub>2</sub> reduction even in low-temperature environments at ~80 ℃, resulting in a higher CO concentration relative to the CO<sub>2</sub> concentration and the highest efficiency of all tested catalysts: conversion efficiency is 18% and energy efficiency is 11%.</p>

    In a liquefied natural gas, gas turbine combined cycle (GTCC) power generation plant that has a high total power generation efficiency, zero carbon dioxide (CO2) emission can be achieved if the energy efficiency of the nonthermal plasma (NTP) CO2 reduction process is at least 49%. In this article, we discuss zero CO2 emission power plants, including introduction to GTCC power plants, carbon monoxide (CO) gas turbine systems, and NTP conversion technologies for converting CO2 into synthesized gas fuels (with the main component being CO) by the recirculation of exhaust gas. To reduce CO2 emissions in a self-consistent manner at room temperature and atmospheric pressure, the method of conversion of CO2 into CO by NTP using reduction technologies is explained. The CO2 reduction performance of the two processes is evaluated experimentally using different gas mixtures. First, CO2 is adsorbed from a gas flow mixture comprising argon (Ar) or helium (He), nitrogen, and CO2 (approximately 10% concentration) onto an adsorbent; afterward, CO2 is desorbed and reduced by Ar or He NTP flow to a higher concentration of 10–22% under similar experimental conditions. An energy efficiency of 20% is achieved in the laboratory with plasma catalysts. The findings indicate that a CO2 reduction of 41% is possible for GTCC plants following the scaling up of the NTP system to an industrial scale.

    An evaluation of the adhesion between rubber and fluoropolymer films treated by atmospheric plasma-graft polymerization is conducted to realize a low-permeation fuel rubber hose covered with fluoropolymer. The low-permeation fuel rubber hose is important for reducing vehicular evaporative emissions. Although fluoropolymers have extremely low permeability for fuel, it is difficult to bond them with other materials, such as rubber, because of their low adhesive properties. Plasma surface modification has been investigated to improve the adhesive properties of fluoropolymers. However, it is difficult to realize effective and permanent surface treatment using plasma alone. Based on the new and effective combined plasma surface-modification technique for fluoropolymer films, we previously proposed an atmospheric-pressure plasma method followed by graft polymerization of hydrophilic monomers such as acrylic acid (CH2 = CHCOOH). In this study, three types of rubber, isobutylene isoprene rubber (IIR), ethylene acrylic elastomer (AEM), as well as white-colored ethylene acrylic elastomer (white AEM), and two types of fluoropolymer films, denatured PFA-1 and denatured PFA-2, were prepared. The treated fluoropolymer film and rubber were adhered using vulcanized adhesion, and then the 180° peeling strength test was conducted. The results show that an average peeling strength of 12.6 N/mm and a maximum peeling strength of 15.3 N/mm, which are over 10 N/mm, are attained for the sample of vulcanized bonding of the treated denatured PFA-1 and AEM.

In liquefied natural gas (LNG) gas-turbine combined power generation plant that have high power generation efficiency, the CO2self-consistency including the power plant can be achieved if the energy efficiency of CO2 reduction by NTP is at least 49%. In this study, CO2 reduction performance is evaluated by two processes using different gas mixtures. First, CO2 is adsorbed from a gas flow mixture of argon (Ar) or helium (He), nitrogen (N2), and CO2 (~10% concentration) by the adsorbent; second, CO2 is desorbed and reduced by Ar or He NTP flow at a higher concentration of 10 to 22% under all experimental conditions. The energy efficiency increases with the elapsed time and reaches 812%. The efficiency increases as Ar / (Ar + N2) 100 takes further away from 50%, and He / (He + N2)  100 takes a lower value. Under all conditions, a part of CO obtained by reduction is further reduced to atomic carbon. If reduction to atomic carbon is taken into account, the energy efficiency significantly increases from 812% to 1622%. The efficiency increases with the higher concentration of Ar and lower concentration of He.

    A combined ozone injection and semi-dry chemical NOx and SOx removal process using nonthermal plasma for the treatment of flue gases emitted from glass melting furnaces has been proposed. To further improve the NOx removal, O3 was injected in directions opposite to the direction of gas flow at the center of the semi-dry reactor. Moreover, the effect of the increase in initial concentrations of NO and SO2 was investigated. In addition, the effect of the gas flow rate on NO oxidation, denitration, and desulfurization efficiencies, and the effect of NaOH and (Formula presented.) concentrations on denitration and desulfurization efficiencies were investigated.
