2、SCR catalytic reduction denitrification system performance advantage

SCR catalytic reduction denitrification systems have the following advantages.

1. Environmental friendliness

The by-products produced by SCR catalytic reduction denitrification system 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 SCR catalytic reduction denitrification system 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.

2. High efficiency denitration capacity

Gate is famous for its high efficiency of denitration, which can usually reach more than 90% denitration efficiency. This means that the SCR catalytic reduction denitrification system technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability mainly benefits from the promotion of catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.

4. economic viability

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 SCR catalytic reduction denitrification system technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR catalytic reduction denitrification system technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

5. Diversity and high efficiency of catalysts

There are many kinds of catalysts used in the SCR catalytic reduction denitrification system 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 SCR catalytic reduction denitrification system technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.
