The national implementation of denitrification electricity prices is coming soon

At the "Flue Gas Denitrification Industry and Technology Forum" held in Beijing on the 12th, with the director of the Ministry of Environmental Protection's total discharge control of pollutants, Liu Bingjiang announced that "the implementation of denitrification electricity prices has entered a countdown", public opinion has been more than a year of smoke The anticipation of the "blowout" development in the gas denitrification industry will become a reality.

On September 21 last year, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued a new "Emission Standard for Air Pollutants from Thermal Power Plants" (GB13223-2011), which requires that new generation of thermal power generators emit nitrogen oxides from January 1, 2012 onwards. It reaches 100 mg/m3; from July 1st, 2014, except for the special unit emission requirement of 200 mg/m3, the rest is also required to reach 100 mg/m3.

This is called "the most severe in history," the thermal power plant emission standards, so that the denitrification of flue gas from thermal power plants becomes the top priority of the "Twelfth Five-Year" emission reduction of air pollutants. Corresponding to this, "the "12th Five-Year Plan" energy-saving emission reduction plan" clearly specifies the nitrogen oxide emission reduction targets, which, thermal power, cement two major industries, the reduction of nitrogen oxide emissions requirements were 29% and 12%; 2015 In 2004, the construction of denitrification facilities for 400 million kilowatts of active coal-fired units was completed, and the technical transformation of low-nitrogen combustion was implemented for 70 million-kilowatt coal-fired units. The denitration efficiency of coal-fired units reached over 75%.

This policy is conducive to the pull of the industry, in the words of Liu Bingjiang, "including the manufacture of related equipment, the manufacture of catalysts, as well as the regeneration and disposal after a period of time in the future." According to the calculation of the Ministry of Environmental Protection, by 2015, the capacity of the existing generating units and new generating units requiring removal of nitrogen oxides will be approximately 817 million kilowatts, which is estimated to require investment of 195 billion yuan and annual operating expenses of approximately 62.1 billion yuan.

According to reports, the most mature denitrification technology currently is the SCR (Selective Catalytic Reduction) system, whose core is the catalyst, which accounts for 40% of the total cost, while the catalyst is a consumable product with a service life of around 24,000 hours, which means that every 3 Change one year. The company launched a set of SCR equipment and invested more than 100 million yuan. In this regard, the state compensates for the policy of giving preferential electricity prices through the discharge of the company's standards.

Prior to this, the denitrification tariff policy brewed by the Ministry of Environmental Protection was based on the subsidy of 0.8 points per kilowatt-hour in 14 provinces. In 2012, it is expected to implement a fiscal subsidy of 1.1 cents per kilowatt-hour across the country. Liu Bingjiang’s “countdown” once said that this “real money” discount that has long been waiting for in the industry has finally led to “boots landing”.

The “Fluid-gas Denitrification Industry and Technology Forum” was initiated by 11 strategic alliances for flue gas denitrification industry technology innovation in the 11 domestic flue gas denitrification fields. The governing units include: CPI Yuanda Environmental Protection and Tsinghua University. , Guodian Longyuan Environmental Protection, Zhejiang University, China National Institute of Standardization, Xi'an Thermal Engineering Research Institute, Blue Sky Environmental Protection Equipment, Nanjing University of Science and Technology, Shanghai Jiaotong University, Chongqing University, Shanghai Bike Energy, etc.

According to the unit of the chairman of the Alliance, CPI Investment Yuanda Environmental Protection, domestic research on flue gas denitrification technology is relatively late. At present, denitrification projects that have been constructed or proposed are almost all based on the purchase of technology use rights in Europe, America and Japan. Some environmental protection companies have also acquired certain flue gas denitrification technologies through independent development or introduction of digestion and absorption. However, core technologies (especially catalysts) have not yet achieved localization, and introduced technologies have high technical fees and poor scalability. .

To this end, the Alliance has jointly undertaken the project of “Development and Demonstration of SCR DeNOx Catalyst for High-efficiency and Low-cost Coal-fired Power Plants” in the National 863 Program. The project consists of four sub-projects, which are aimed at importing and denitrifying raw materials for flue gas denitration catalysts of coal-fired power plants in China. With higher costs and other issues, the key raw material for denitrification catalysts, titanium-tungsten powder, was selected as the breakthrough point to develop localized, high-efficiency, low-cost honeycomb catalysts, and to develop denitrification catalysts and production technologies suitable for a wide temperature range, through comprehensive integration of technologies. , To demonstrate industrial application and engineering in large-scale power station boilers, and to realize the localization of the overall industrial chain of SCR denitrification catalysts.

At present, the project led by China Power Investment Yuanda Environmental Protection, Tsinghua University, Chongqing University, etc., “Preparation Technology of Catalyst Key Raw Materials and Research on Formulations Based on Raw Materials”, has completed research and development tasks, and developed a dedicated titanium tungsten with independent intellectual property rights. The powder preparation process has established an ultra-fine titanium tungsten powder production line with an annual output of over 1,000 tons, formed a domestic catalyst formula with independent intellectual property rights, freed itself from the dependence on foreign titanium-tungsten powder, and realized the localization of key raw materials for catalysts, saving The catalyst cost is about 30%.

According to the alliance, a breakthrough in national policies and the addition of core technologies has given rise to a large-scale launch of the SCR denitrification catalyst market. It is expected that the denitrification catalyst demand will reach 500,000 cubic meters in 2010-2020. The use of self-titanium-tungsten powder can save costs about 2.2 billion yuan; while the promotion of wide-temperature catalysts, compared to the existing medium-temperature commercial catalyst, the cost is reduced by about 20%, the reduction of nitrogen oxides is about 17 million tons, and the economic loss is reduced by 27 billion yuan. .

Liu Bingjiang talked about his views on how the “big cake” of flue gas denitrification came. He told everyone that denitrification is an important part of the "12th Five-Year Plan" energy-saving and environmental protection industry. "It must be stronger and bigger." He said that it is not a problem to expand now. By the end of this year, the domestic denitrification power plant has reached 200 million kilowatts, and denitrification of cement and glass furnace flue gas will reach 100 lines by the end of 3 lines; by the end of 2015, 700 million will be completed. Kilowatts of denitrification installed, there is no problem. However, he also stressed that strengthening is the key. At present, there may be more than 60 manufacturers of denitrification catalysts in the country, some of whom are picking up small workshops and making use of them. This “flowering” situation like the “Eleventh Five-Year” desulfurization “cannot be repeated”. Liu Bingjiang disclosed that early next year, the Ministry of Environmental Protection will organize a team of 300 people to verify the reduction of nitrogen oxides emissions. “The key point is to see how the denitrification project quality is and how it operates.”
