Project Title: System for Removal of the Oxides of Nitrogen and Sulfur from Incinerator Effluents

Technical Abstract (Limit 200 words)

Long duration missions will use plant growth to produce food and oxygen. However, plant-based systems produce large amounts of waste biomass, much of which will ultimately be burned. In addition to producing CO2 and H2O, this process also makes a variety of harmful by-products including particulates, CO, hydrocarbons, SO2 and NOx. Current systems for removing acid gases such as SO2 and NOx use a combination of selective catalytic reduction (of NO) and absorption on copper oxide (a low capacity SO2 sorbent). Because this method only reduces NOx by 50%, a carbon bed is needed to complete the process, leading to large expendable consumption in addition to the use and emission of ammonia, a hazardous and toxic chemical. TDA Research Inc. proposes to remove these acid gases by oxidizing the NO to NO2, absorbing SO2 and NO2 in water, neutralizing the acids, and concentrating the resulting salts into a small amount of olution. The result is a safer, more effective process for acid gas control and a significant reduction in consumable materials required.

Potential Commercial Applications (Limit 200 words)

The successful demonstration of NOx control technology would find immediate application in many areas, including control of emissions from gas turbine power generators and nitric acid plants.
