Abstract: Incentives for implementing new pollution-control technologies are
both regulatory and economic. Given considerable regulatory pressure, new de-NOx
technologies are being explored. One major reason for this is that conventional
de-NOx methods will not work effectively for the low NO concentrations (e.g., <50 ppm), high exhaust gas flow rates, and low gas temperatures characteristic of jet engines test cells (jetcs). this project is currently evaluating non-thermal plasma (ntp) technologies for treating jet-engine exhaust. in the past, economic analysis for ntp de-nox has shown that it is not cost effective, compared to other techniques. one might accept a high-cost system, if it can provide a
function or functions that other (conventional) technologies cannot. However, it
would certainly be better if a new technology could function as well or better
than a conventional technology and do so at competitive costs. In this White
Paper, we have analyzed the costs of some NTP technologies for jet-engine
emissions control. In some cases, these analyses have shown lower exhaust-gas
treatment costs for NTP systems compared to a baseline standard de-NOx
technology like SCR combined with wet scrubbing. Therefore, the main conclusion
of this White Paper is that completing this project's work through the small
field-pilot demonstration phase should proceed to provide further data and
operating experience to more fully evaluate economic and performance projections
for NTP de-NOx technology.
