The Electro-Catalytic Oxidation (ECO) system is an integrated air pollution control technology that achieves major reductions in the primary air pollutants of concern from coal-fired power plants, specifically 99% reduction of sulfur dioxide (SO2) emissions, 90% of nitrogen oxide (NOx) emissions, 80-90% of mercury (Hg) emissions, and 95% of fine particulate matter (PM2.5) emissions. The system also provides high removal of other metals and acid gases such as sulfuric acid (SO3/H2SO4), hydrochloric acid (HCl), and hydrofluoric acid (HF). The ECO system produces a valuable, ammonium sulfate fertilizer co-product, reducing operating costs and minimizing landfill disposal of waste.
