Epcon and NOx Abatement

Epcon uses several time-honored strategies to abate the formation of NOx, a noxious mixture if the pun may be excused.

NOx and Sox emissions are components of acid rain. When mixed with these toxic emissions in the clouds with the presence of water vapor; nitric and sulphuric acid is formed. NOx also is an active ingredient in smog (photochemical ozone). By reacting with VOCs (volatile organic compounds) in the presence of sunlight, “smog” becomes a potent and dangerous respiratory and eye irritant. NOx is primarily composed of NO and NO2, although most thermal NOx is NO.

Acid rain first became well-known to the public during the early 1970s when toxic clouds hovering over the American Appalachian lands began making its chemical presence felt, as a type of precipitated smog. Episodes of smog have become synonymous with air pollution, most typically and in its strongest concentrations over urban areas configured in a manner where pollutants are somehow trapped. Atmospheric anomalies such as temperature inversions between cold and warm layers also can influence the formation and maintenance of smog outbreaks, such as what was experienced in Salt Lake City during the winter of 1976.

Epcon has chosen several effective strategies proven efficacious in abatement of industrial-caused NOx environments. These strategies involve the reduction of fuel NOx via the use of low Nitrogen gaseous fuels, and the control of oxidation of nitrogen bound hydrocarbons; combustion modifications involved in the reduction of thermal NOx, which is a by-product of unnecessarily high temperatures in the flame and flue gas clean-up.

Combustion modifications can be brought about by reducing the flame temperature through premixing fuel and air, and by decreasing the O2 content with flue gas recirculation (FGR). Flue gas clean-up is simply a way to eliminate unavoidable NOx. The Epcon-approved methods here are Selective Catalytic Reduction (SCR), Selective Non-Catalytic Reduction (SNCR), and newer technologies such as catalytic absorption and wet scrubbers. Industries served include commercial sector, prime contractors, government, NQA-1, and ASME.
