NO/sub x/ removal in jet-engine exhaust: proposed non-thermal plasma systems and economic considerations

Summary form only given. Incentives for implementing new pollution-control technologies are both regulatory and economic. Given considerable regulatory pressure, e.g., the promulgation of a NESHAPS (National Emissions Standard for Hazardous Air Pollutants) for NO/sub x/ emissions in CY 2000, new de-NO/sub x/ technologies are being explored. One major reason for this is that conventional de-NO/sub x/ methods (like wet scrubbers plus selective catalytic reduction) will not work effectively for the low NO concentrations (e.g., <50 ppm), high exhaust-gas flow rates (/spl sim/10/sup 6/ Nm/sup 3//h), and low gas temperatures (near ambient) characteristic of jet engine test cells. Our project is currently evaluating nonthermal plasma (NTP) technologies for treating jet-engine exhaust and other hazardous air pollutants. In this paper, we will present our initial design options for NTP reactor systems for a field-pilot demonstration on small jet engines (e.g., F107 or F112; flow rates /spl sim/10/sup 4/ Nm/sup 3//h).
