"Limited order" forced cement and other billions of industrial upgrading

After March 1, if we want to build six heavy pollution industries such as thermal power, iron and steel, petrochemical, cement, non-ferrous metals, and chemical industries in the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta and coal-fired industrial boiler projects, we will face more stringent Air pollutant emission standards. However, existing projects in these areas will also need to follow more stringent emission standards.

The Ministry of Environmental Protection said on the 19th that it will implement special emission limits for air pollutants in key controlled areas, strictly control the amount of new air pollutants, and force industrial upgrading and technological advancement, thus contributing to the continuous improvement of atmospheric environmental quality. This will directly motivate hundreds of billions of enterprise technology upgrades.

Promote hundreds of billions of yuan in industrial upgrading At present, air pollutant emissions standards and special emission limits for thermal power and iron and steel industries have been issued, and the "Cement Industry's Emission Standards for Air Pollutants" (including special emission limits) has been completed for the first time. opinion. According to a source from the Ministry of Environmental Protection, standards for other industries are being worked out and the time has not yet been set.

These key control areas include Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta regions, Central Liaoning, Shandong, Wuhan and its neighboring areas, Changsha-Zhuzhou-Xiangtan-Chongqing-Chongqing-Chongqing-Taiwan-Strait-Strait-West Coast, Shanxi-Central-North, Shaanxi Guanzhong, Ganning, and Xinjiang Urumqi. Waiting for 47 cities. In these regions, from March 1 onwards, newly accepted thermal power and steel EIA projects will implement special emission limits for air pollutants; coal-fired power generation units in existing projects within the main urban area of ​​47 cities from 2014 The special emission limits for fumes will be implemented from July 1st onwards. Special emission limits for particulates will be imposed on the head of sintering (pellet) equipment in the iron and steel industry from January 1, 2015. The petrochemical industry and coal-fired industrial boiler projects will be subject to corresponding emission standards. After the revision, improvement, and definition of special emission limits, the specific emission limits for volatile organic compounds and soot are respectively implemented after the transition period of existing projects set in accordance with the standards.

“The special emission limits involved and the principles for the development of emission standards are based on the announcement No. 17 issued by the State Environmental Protection Administration in 2007 on the issuance of the “Guiding Opinions on Strengthening the Amendment and Amendment of National Pollutant Emission Standards”,” According to a person from the Standardization Department of the Ministry of Environmental Protection, “The overall principle is that according to the actual situation in China and the needs of environmental management, the standards will be very strict in some areas where the pollution is particularly serious.”

According to an announcement by the industry insiders called “No. 17 Document”, the emission standards should address the characteristics of the pollution sources established after the implementation of this standard and the existing pollution sources that existed before the implementation of the standards, and separately put forward emission control requirements so that relevant parties can pass Emissions standards Understand the environmental access requirements at a certain time in the future and the exit requirements of existing pollution sources. For newly established sources of pollution, strict emission control requirements should be set in accordance with international advanced pollution control technologies; existing sources of pollution should be set according to more advanced technologies and emission control requirements must be established within a certain period of time to reach or approach new pollution sources. Control requirements. Emission standards proposed emission control requirements should be advanced, able to represent the industry's advanced clean production technology and pollution control technology development direction, the backward energy consumption, material consumption, and serious pollution, can not be used as the technical basis for the preparation of standards.

The issued draft of “Emission Standards for Air Pollutants in the Cement Industry” (Preparation Statement) and the “Draft Air Pollution Emission Standard for Thermal Power Plants” (Secondary Exposure Draft) all show new emission standards and special emission limits. Values ​​are based on surveys of tens to hundreds of corporate samples, based on analysis of the company’s advanced technologies and emissions, as well as analysis of international advanced technology use and emissions, and reference to other national standards.

Take the draft of the “Cement Industry Air Pollutant Emission Standard” issued on November 6, 2012 as an example. According to the investigation of smoke (powder) dust, one of the major atmospheric pollutants emitted during the cement production process, the 160 valid sample data retrieved from the exposure draft show that it is compared with the sample survey of the 2003 compilation standards (ie current standards). The cement kiln tail particle concentration decreased significantly from an average of 100.9 mg/m3 to the current average of 27.4 mg/m3, close to the European emission level.

“The vast majority of cement kilns (about 95%) meet the requirements of the current standard of 50 mg/m3, which shows that with the advancement of dust removal technology, emission standards have been tightened. 60% of cement kiln particulate emissions are controlled at 30 mg/m3. In the following, even 32% of the cement kilns have reached 20 mg/m3 or less.Accordingly, the standard revision will increase the concentration of cement kiln particulates from 50 mg/m3 to 30 mg/m3, reaching the average of European countries or Permit limit level; and cement companies in key areas require further control to 20 mg/m3 or less (Germany's environmental protection standards are very strict, the current limit value is 20 mg/m3).” .

“The standards of Germany are generally strict. Some of the standards are referenced to foreign countries and some are based on the actual situation in the country. In areas where the pollution is particularly severe, the standards may be very strict.” According to the aforementioned person from the Ministry of Environmental Protection Standards Department, “The formulation of emission standards and special emission limits for petrochemical, chemical, nonferrous metals and cement industries, and coal-fired industrial boilers in the process of revision are also based on the 'No. 17 Document'.”

Special emission limits According to the 12th Five-Year Plan for Prevention and Control of Air Pollution in Key Areas issued by the Ministry of Environmental Protection on December 5, 2012, during the “Twelfth Five-Year Plan” period, air pollution prevention and control in key regions will include the treatment of There are 8 types of key projects such as recycling, yellow mark car elimination, comprehensive dust control and capacity building, and the investment demand is about RMB 350 billion.

According to the “Cement Industry's Air Pollutant Emission Standards” currently being drafted, the drafters of the China Academy of Environmental Sciences and Hefei Cement Design and Research Institute have shown that the existing production line has reached the target transformation cost of approximately RMB 17 billion. In order to achieve the “12th Five-Year Plan” predicted by the “Cement Industry,” the forecast of the “12th Five-Year Plan” at the end of the year, the cement demand will be 2.2 billion tons/year, and the national environmental protection investment for the new production line will be about 7 billion yuan. If calculated according to an annual output of 2 billion tons of cement, the operating cost of the national environmental protection facilities will reach 24 to 30 billion yuan.

"The stricter the standards, the greater the difficulty of control, the higher the cost of controlling the operation and the cost of operating the environmental protection facilities. There will certainly be some impact," said Huang Dao, Director of the Energy Conservation Division of the China Iron and Steel Association. "Now the operating status of steel companies and industries It is not good, so governance pressure is relatively large, but when the emission standards for pollutants in the steel industry were released last year, it was already mentioned that special emission limits should be imposed on key control areas, so steel companies have already been prepared for it. 'Efforts have been made in the past few years. Although some indicators are more difficult, they can still be achieved in general.'

For the “Emission Standard of Air Pollutants for Thermal Power Plants” that began on January 1, 2012, the power industry has always considered the standards to be too high and the upgrading costs to be too high. To this end, the National Development and Reform Commission will increase the denitrification price and increase the on-grid tariff at the end of November 2011 to help alleviate the financial pressure on the power industry.

Both the China Petrochemical Federation and the China Nonferrous Metals Industry Association have stated that they “will comment on the inconvenience of policies that have not yet been introduced”.

However, the surveys conducted by the China Academy of Environmental Sciences and the Hefei Cement Design Institute also show that according to the transformation of the new standard, the cement industry is expected to be realized, particulate emissions can be reduced by 38.5%, and nitrogen oxides emissions can be reduced by 39.3%. According to the “Twelfth Five-Year Plan” for the Prevention and Control of Atmospheric Pollution in Key Areas, by 2015, the emissions of NO x, nitrogen oxides, and industrial smoke dust in the aforementioned key areas must decrease by 12%, 13%, and 10%, respectively. The average annual concentration of fine particles in the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta must fall by 6%.

Hao Jiming, academician of the Chinese Academy of Engineering and dean of the Environmental Science and Engineering Research Institute of Tsinghua University, believes that strict control measures may have an impact on economic growth in the short term, but it can help promote the green transformation of economic development methods and promote the upgrading of pollution prevention and control in related industries. Industrial structure adjustment.
