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 Electro-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.

  • The Physics Behind the Power of an Engine

    Ideally an engine takes in Air (Oxygen and Nitrogen) and fuel (hydrocarbons) and produces CO2, H2O, and the N2 just passes through. However under normal driving conditions an engine will encounter lean conditions when cruising on the highway (better mileage) and rich conditions when accelerating (better power). The lean condition results in oxide and harmful nitrogen production. Rich conditions result in carbon monoxide production. For this reason catalytic converters are used on an engine’s exhaust.

    Fossil fuels, such as coal and oil, are Carbon rich compounds, the combustion of which produces Carbon Dioxide, a pollutant and a greenhouse gas. A large amount of energy is released during this process, which is why the pollutants off products are tolerated. This process occurs constantly throughout the world, in power stations, vehicles and cooking ovens, leading to an immense volume of CO2 being released every second, 50% of which is absorbed by oceans (Oce...

    ...ese dangerously harmful gasses would be released into our atmosphere by all combustion engines. Although the catalytic converter when operating at its optimal temperature can break down over 95% percent of the harmful gasses produced by the engine it does not do a well at all when not at high temperatures. It takes about five miles of driving for most vehicles to reach a temperature at which the reactions will reach near completion, before this temperature the catalytic converter does practically nothing to convert these harmful gases. Some catalytic converters now have coils running from the engine to the catalytic converter to heat the catalytic converter to its optimal temperature soon after the engine has started to produce harmful gasses. With this improvement the catalytic converter can effectively reduce almost all of the carbon monoxide and nitrogen oxide.

  • Catalytic Converters

    There are millions of cars on the road in the United States, and each one is a source of air pollution. Especially in large cities, the amount of pollution cars produce everyday is a lot. To solve those problems, many laws have been enacted restricting the amount of pollution that cars can produce. To make their cars as pollution-free as possible, automakers have made many refinements to car engines and fuel systems and have developed the catalytic converter. The catalytic converter treats the exhaust before it leaves the car, and removes a lot of the pollution.
