Feasibility analysis report for hybrid non-thermal plasma reactors

摘要

The purpose of the Strategic Environmental Research and Development Program (SERDP) project CP-1038 is to evaluate and develop non-thermal plasma (NTP) reactor technology for Department of Defense (DoD) air emissions control applications. The primary focus is on oxides of nitrogen (NO(sub x)) and a secondary focus on hazardous air pollutants (HAPs), especially volatile organic compounds (VOCs). Examples of NO(sub x) sources are jet engine test cells (JETCs) and diesel-engine powered electrical generators. Examples of VOCs are organic solvents used in painting, paint-stripping, and parts cleaning. Because pollutant-containing air-emission streams within the Department of Defense (DoD) frequently span a broad range of pollutant concentrations, flow rates, and gas conditions (e.g., temperature, humidity), a single type of NTP reactor is not expected to fit all types of emissions streams. Additionally, stand-alone NTP reactors may provide neither an adequate means of pollutant removal nor an acceptable economic solution. Therefore, hybrid systems (combinations of different NTP reactor types or architectures), which employ adsorbents and/or catalytic media are being examined by researchers in this field. This report is intended to provide a preliminary summary analysis of a few representative hybrid systems as a means of introducing the hybrid or staged-system concept.
