Energy Consumption and Optimal Reactor Configuration for Nonthermal Plasma Conversion of N₂O in Nitrogen and N₂O in Argon

Abstract

The analysis of experimental data, chemical reaction mechanisms, and kinetic modeling data is used to determine the power input and pulsed-corona-discharge reactor configuration that minimizes energy consumption for converting N 2 O in nitrogen and N 2 O in argon, which are model binaries reminiscent of more complex NOx in flue gas systems. Specifically, it is found that inseries reactors are much more energy efficient than a single reactor and more energy efficient than parallel reactors. For example, 12 reactors in series are needed to remove 90% of N 2 O if its initial concentration in nitrogen is about 200 ppm.

Effect of CO on NO and N2O conversions in nonthermal argon plasma

“…The experimental apparatus and measurement procedures are described in detail elsewhere. 11,13 In brief overview, the pulsed corona discharge reactor used in this work consists of a high-voltage power supply and a pulser/reactor assembly. The pulser/reactor assembly contains a pulsed power generator and pulsed corona discharge tubes.…”

“…The feed samples and the reactor effluent samples, collected in small stainless steel cylinders, are analyzed for stable species with a Spectrum 2000 Perkin Elmer Fourier transform infrared ͑FTIR͒ spectrometer with a narrow band mercury cadmium telluride ͑MCT͒ detector, as reported previously. [5][6][7][8][9][13][14][15] For all experimental data, nitrogen oxides other than NO, NO 2 , and N 2 O are not detected by FTIR, which has a detection limit of 5 ppm for each of these species. All experimental data are reproducible within a ±10% error limit, including the FTIR and flow measurement uncertainties.…”

Effect of reactor configuration on nitric oxide conversion in nitrogen plasma

“…They found that the energy efficiencies of both NO and NO x decomposition slightly increase with reactor length, but are not strongly dependent on it. Recently, Zhao et al9 investigated the effects of series and parallel operation of multiple PCDRs on energy consumption during N 2 O conversion. They found that series reactors are more energy efficient than a single reactor and parallel reactors.…”
