May 06, 2025

In recent years, with the increasing requirements for environmental protection and green development, my country has made significant breakthroughs in flue gas desulfurization and denitrification technology. The innovation of these technologies not only provides new impetus for industrial emission management, but also makes important contributions to the realization of national environmental protection goals. The improvement of flue gas desulfurization and denitrification technology not only helps to reduce the emission of atmospheric pollutants, but also plays a key role in reducing greenhouse gas emissions and improving air quality.
Technological innovation drives green development
Flue gas desulfurization and denitrification technology is mainly used to treat waste gas emissions from thermal power, steel, cement and other industries, reduce the emission of harmful gases such as sulfur oxides (SO2) and nitrogen oxides (NO_x), and reduce pollution to the environment. In recent years, my country has continuously increased its R&D investment in this field, promoting a number of breakthroughs in desulfurization and denitrification technology. In particular, significant progress has been made in the research of "ultra-low emission" technology.
For example, the low-temperature denitrification technology developed by some domestic enterprises and scientific research institutions has effectively reduced the emission of nitrogen oxides through innovative catalysts and reaction methods. Compared with traditional high-temperature denitrification technology, this new technology can not only treat pollutants in flue gas more efficiently, but also reduce energy consumption and increase the service life of equipment. In addition, desulfurization technology is also continuously innovating. The combination of liquid absorption method and dry desulfurization technology has significantly improved the desulfurization efficiency and reduced the emission of by-products during the treatment process.
Helping to achieve environmental protection goals
In recent years, the Chinese government has introduced a series of strict environmental protection policies, requiring enterprises in key industries to take effective desulfurization and denitrification measures to achieve the standard of atmospheric pollutant emissions. The "Comprehensive Emission Standards for Atmospheric Pollutants" implemented in 2020 clearly requires coal-fired power plants and other high-pollution emission industries to gradually achieve "ultra-low emissions", which provides a huge impetus for the development of flue gas treatment technology.
Through technological innovation, Chinese companies have been able to achieve efficient flue gas treatment in many key industries, especially in thermal power, steel, cement and other industries. According to statistics, the coverage rate of flue gas desulfurization and denitrification facilities in my country's thermal power industry has reached more than 95% in 2022, and the emission indicators of many companies have reached or are close to the international advanced level. The application of these technologies has made positive contributions to my country's battle to protect the blue sky and improve air quality.
Challenges and Prospects
Although my country has made significant progress in the field of flue gas desulfurization and denitrification, it still faces some challenges in the face of increasingly stringent environmental protection standards and increasingly complex pollutant emissions. First, the existing technology still has certain limitations when treating waste gas in some special industries. For example, the waste gas of some industries contains a large amount of ammonia and nitrogen compounds, and traditional denitrification technology is difficult to treat efficiently. Secondly, the construction and operation costs of desulfurization and denitrification facilities are high, and some small and medium-sized enterprises may face financial pressure and find it difficult to update technical facilities in a timely manner.
However, with the advancement of science and technology, more flue gas treatment technologies with more efficient, low-cost and low-energy consumption characteristics will be gradually promoted and applied. In addition, the support of government policies and increasingly stringent environmental protection regulations will also drive more companies to increase investment in environmental protection technologies.
Conclusion
Overall, my country's innovative breakthroughs in the field of flue gas desulfurization and denitrification technology have provided strong support for the realization of environmental protection goals. With the continuous advancement of technology and the continuous advancement of policies, my country will surely achieve greater results in flue gas treatment in the future, and make greater contributions to promoting green development and achieving carbon neutrality goals. At the same time, industry enterprises should also strengthen technological innovation and equipment upgrades, actively respond to future environmental challenges, and jointly contribute to the beautiful vision of blue sky and clear water.
