Initial Designs of Electric-Discharge Non-Thermal Plasma Field-Pilot Demonstration Units for NOx Removal in Jet-Engine Exhaust: White Paper for SERDP Project CP-1038

摘要

Incentives for implementing new pollution-control technologies are both regulatory and economic. Given considerable regulatory pressure, e.g., the promulgation of a NESHAPS for NOx emissions in CY 2000, new de-NOx technologies are being explored. This project is currently evaluating non-thermal plasma (NTP) technologies for treating jet-engine exhaust and other hazardous air pollutants. To meet a project milestone this White Paper will present our initial design options for NTP reactor systems for a field-pilot demonstration on Cruise Missile Test Cell (CMTC) exhaust at Tinker AFB. The field-pilot demonstration is necessary to provide further data and operating experience to more fully evaluate economic and performance projections for NTP de-NOx technology and to design larger systems with confidence. From the design options presented here, we will downselect the set to 2 treatment systems and consider fielding both. If the budget is not sufficient for 2 reactor systems, only one will be fielded. This paper will discuss the exhaust stream to be addressed, the test setup, the candidate reactor systems, and projected operating parameters and specifications for the field-pilot units. Because the cost and logistics of using an electron-beam NTP reactor are, respectively, too high and too complicated for this project, we have limited our candidate systems to those based on electric-discharge-driven NTP reactors (which previous economic analyses have shown to be more cost effective).
