DanaTech has been developing a new technology for reducing pollutants from combustion effluent gases. This technology relies on a narrow controlled wavelength band of ultraviolet energy that causes two pollutants in the gas stream to react together. These pollutants are classified as reactive organic gases (ROG) and oxides of nitrogen (NOX). These pollutants are found in flue gases from engines, boilers, and other combustion devices. Some ROG species have been found to be toxic and cancer promoters and they are of great concern to regulatory authorities. In addition, many ROG compounds are precursors to aerosols which are very fine particles that are also highly regulated. NOX molecules are known smog precursors and continue to be highly regulated.
Testing at a cogeneration plant in Los Angeles has shown that this process could reduce NOX to less than 1 ppm in certain effluent gases. Kinetic research conducted so far concludes that the UV technology converts the reactants to nitric acid which can be easily scrubbed out with sodium hydroxide to form sodium nitrate, an important nitrogen bearing fertilizer. The market strategy with this technology is to destroy two pollutants in effluent stack gases to make fertilizer. It will have application on a world scale.
