Zero Emissions Technology Zero Emissions Technology: Current Technologies and Future Developments in Electrostatic Precipitators  Abstract Zero Emissions Technology is a company located in New Durham, NH. They develop new technologies targeted at coal fired power plants. They have recently developed a new air emissions technology that will meet current and pending air pollution regulations. Their product, Electro-Catalytic Oxidation Technology, allow the combined removal of particulates in the air waste stream. The new technology can be retrofitted onto existing electrostatic precipitators (ESP), according to the industry, is not as expensive as other air pollution control technologies. The Electro-Catalytic Oxidation Technology also has many technological advantages to more conventional ESPs.  Zero Emissions Technology (ZET) is a company who develops new technologies in air pollution control technologies to meet the demands of new regulations on air emissions. In the past, their focus has been on air pollution control technology for large stationary sources, such as coal fired power plants. In the future, their research will be to discover new technologies not only for air pollution, but also in water and solid waste. (ZET, 1999). Zero Emissions Technology has developed a new technology that focuses on the combined removal of particulates for coal fired power plants. Electro-Catalytic Oxidation Technology is a product by Zero Emissions Technology (ZET). This new technology that ZET is has developed will enable the combined removal of nitrogen oxides (NOx), sulfur dioxide (SO2), mercury (Hg), and fine particulate matter (PM2.5) from the flue gas of coal fired power plants. This new technology will collect at least 70% of NOx, 50% of SO2, 70% of mercury (Hg), and 90% of PM2.5 in a single unit that can be retrofitted into the last fields of existing electrostatic precipitators (ESP) (ZET, 1999). This will allow coal fired plants to meet new air emission requirements with minimal impact on their generating costs. It can be retrofitted into the last fields of existing ESP. Electo-Catalytic Oxidatin Technology uses a proprietary gas discharge technology to convert NOx and SO2 to acid mists, and to oxidize elemental mercury. It also uses advances in wet ESP technology to remove acid mists and other fine particles without saturating flue gas. The Electr o-Catalytic Oxidation system consists of three sections: gas converter, condensing wet ESP, and acid recovery (ZET, 1999). The Gas Converter is used for the electrical oxidation of NOx, SO2 and Hg. As the flue gas enters the Gas Converter, it is exposed to a high voltage discharge which creates ionized species to oxidize pollutants.
