Abstract : McClellan AFB, California, identified mobile diesel engines as contributing nearly as much oxides of nitrogen (NOx) emissions as aircraft and permitted stationary sources combined. Hourly-rated diesel engines contributed 75 percent of this NOx, with the remainder emitting from gasoline and diesel engines rated in miles. The Armstrong Laboratory Environics Directorate at Tyndall AFB, Florida, with the support of Applied Research Associates and Sorbent Technologies, has developed and demonstrated a simple and effective technology for reducing non-road diesel NOx and other air pollutant emissions. The filter cart was designed to control emissions of NOx, particulate, and unburned hydrocarbons (UHCs) from mobile diesel generators. It uses a simple vermiculite-based filter to capture particulate, a large air-to-air heat exchanger to cool the gas, a demister to remove condensable liquids, and rows of activated carbon (AC) filters to adsorb NOx and UHCs. A separate stand-alone system is used to desorb and destroy the contaminants adsorbed on the AC filters. Over 90-percent removals of NOx by the filter cart have been repeatedly demonstrated in the field.
