Abstract:
This invention presents an NO. sub. x environment effective reduction apparatus comprising a sulfur tolerant, high water vapor (about 3% to about 18%) tolerant, packing-free coronal-catalyst. In one embodiment the invention comprises an NO. sub. x reduction apparatus of high water vapor tolerant coronal-catalyst adapted and configured for hypercritical presentation of an electrical field to an NO. sub. x bearing gas stream, where the electrical field has a minimum field power density of at least about 75 watts/cubic meter, and optionally, accompanying downstream scrubbers. In a particular embodiment, downstream wet or dry absorption arrest particular NO. sub. x reduction products NO. sub. 2 and HNO. sub. 3, optionally upon exposure to an arresting agent, including basic, caustic, or alkali materials such as CaO or NH. sub. 3.
