2、Catalytic denitrification characteristics

The Catalytic denitrification features are as follows:

  1. High denitration efficiency
  2. The denitration efficiency of Catalytic denitrification technology can reach more than 90%, and it is a widely used post-combustion denitration technology at present.

  3. Small secondary pollution
  4. The by-products produced in the Catalytic denitrification opening process are nitrogen and water vapor, and there is no secondary pollution problem.

  5. selectivity
  6. Under the action of catalyst, the reducing agent mainly reacts with NOx selectively, but less with other components (such as oxygen) in flue gas, thus reducing unnecessary consumption.

  7. high efficiency
  8. Gate technology can effectively remove NOx from flue gas, and the denitrification efficiency can usually reach more than 90%.

  9. Strong adaptability
  10. Catalytic denitrification technology can meet the needs of flue gas denitrification under different working conditions and has a wide range of applications.

6、Functional advantages of Catalytic denitrification

Catalytic denitrifications have the following advantages.

  1. Wide applicability
  2. Catalytic denitrification technology is suitable for many industries and processes, such as coal-fired power plants, iron and steel smelting, cement production and so on. These industries will produce a large number of NOx emissions in the production process, and the Catalytic denitrification technology can provide effective denitrification solutions for them. In addition, the gate technology can be adjusted and optimized according to different flue gas components and emission requirements to meet different denitration requirements.

  3. Intelligent control and convenience of operation
  4. The Catalytic denitrification has gradually realized intelligent control. By integrating advanced control system and sensor technology, the Catalytic denitrification can monitor the composition and emission concentration of flue gas in real time, and automatically adjust the injection amount of reductant and the active state of catalyst to ensure the stability and reliability of denitrification efficiency.

  5. Environmental friendliness
  6. The by-products produced by Catalytic denitrification technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution. Compared with the traditional wet flue gas denitrification technology, the Catalytic denitrification technology does not need to use a lot of water resources and will not produce pollutants such as wastewater, which is more in line with the requirements of environmental protection and sustainable development.

  7. Diversity and high efficiency of catalysts
  8. There are many kinds of catalysts used in the Catalytic denitrification technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at low temperature. At the same time, the active components and carrier materials of the catalyst are constantly being developed and improved to improve its catalytic efficiency and service life. This enables the Catalytic denitrification technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.

  9. economic viability
  10. The initial investment of this technology may be high, but in the long run, its economic feasibility is remarkable. The high-efficiency denitration ability of Catalytic denitrification technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, Catalytic denitrification technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.
