Recently, Vice Minister of Environmental Protection Zhang Lijun's news in the investigation and investigation of the pollution reduction work in the cement industry by Conch Group caused a lot of shock in the cement industry. The reason is that the views expressed by Vice Minister Zhang were crisp and clear, and the tasks were clear. Not negotiable.
Vice Minister Zhang’s opinion focused on the issue of reducing nitrogen oxides in the cement industry and summarized them as follows;
1. During the “12th Five-Year Plan†period, the cement industry is a key industry for the reduction of nitrogen oxides. The annual new cement production in the country accounts for more than 80% of the world's new production. In 2011, the cement output will exceed 2 billion tons, and the nitrogen oxides will be emitted. The second largest industry after volume becomes electricity;
2. The nitrogen oxide emission standard of thermal power plants is now 100 mg/standard cubic meter, and the nitrogen oxide emissions of the new dry-process cement kilns are generally around 800 mg/standard cubic meter. The emission standards that the Ministry of Environmental Protection is studying will be very strict. In the cement industry that was promulgated and implemented last year, new demolition equipment with an efficiency of not less than 60% must be installed in the newly renovated and expanded project.
3. The “Twelfth Five-Year Plan†pollution reduction task is even more arduous. At present, especially the pressure of nitrogen oxide emission reduction is huge. The “12th Five-Year Plan†cement industry plan also specifies the target of a 10% drop in nitrogen oxide emissions. At present, the national emission of nitrogen oxides does not fall, but the situation of emission reduction is very serious. The cement industry must actively take measures to reduce emissions.
4. Conch Group, as a leading company in China's cement industry, should take concrete steps to take concrete actions to reduce emissions of cement nitrogen oxides.
The signal released by this news should be clear, that is, after power, "it is the turn of cement denitrification on the stage."
However, it seems that there have been some different interpretations, focusing on what level the standard should be set at. Europe is ahead of the world in terms of denitrification, and the standards that they are currently implementing have a leading role. On the other hand, China's land area is slightly smaller than that of Europe, while cement production accounts for more than half of the world's production and is several times that of Europe's. It is not unreasonable to implement even more stringent standards than in Europe. The differences between these standards discussed are not yet essentially at a different level from a technical point of view; from the point of view of investment, there is no significant difference in the amount of investment; from the management point of view, Nor will it cause a sudden increase in administrative difficulty. Therefore, it is not necessary to pay too much attention to the current emission standard of 500 mg/standard cubic meter or 400 mg/standard cubic meter. The Ministry of Environmental Protection of the People's Republic of China will fully conduct investigations and studies, listen to opinions from all quarters, and formulate "rigorous" standards.
The first goal of the “Twelfth Five-Year Plan†of the National Environmental Protection Plan is that the total discharge of major pollutants will be significantly reduced by 2015. The first of the three major measures formulated in the "Plan" has "encouraged local governments to formulate more stringent pollutant discharge standards." Article 3 has "enhanced nitrogen oxide emission reduction efforts. Accelerating other industries (referring to electricity In addition to the denitrification pace, at the Seventh National Environmental Protection Conference, the Ministry of Environmental Protection and local governments signed the Responsibility Document for the total amount of major pollutants for the “Twelfth Five-Year Planâ€, which shows that the central government encourages local strictness and speeds up denitrification. Step by step, implement total emission reduction target responsibilities, therefore, when companies consider emission reduction measures, they will only benefit the sustainable development of the enterprise. Controlling emission concentration is an important aspect of environmental protection, but with the development of economy, control It is also a matter of time for emissions to use emissions as the main basis for pollution control, so it is an inevitable task for companies to strictly control emission concentrations and reduce total emissions.
If you say that in the "China Cement Environmental Protection Conference and Cement Denitrification and Dust Collection Seminar" organized by China Cement Network in October last year, only environmental protection research and design institutes and environmental protection companies demonstrated the technologies developed in terms of nitrogen oxide emission reduction. With the equipment and research directions, and the cement companies as “students†attending lectures, then, just a few months after the conference, the situation of nitrogen oxides emission reduction becomes more severe, and pressure on cement companies is getting more and more. Big. Sichuan and Guangdong Provinces have also issued implementation opinions on the reduction of nitrogen oxides in the province after Hunan (September). Some denitrification devices with model significance have also obtained gratifying results in the cement production line. It has been reported that the denitrification device installed by Zhejiang Juzhou Juhua Cement Plant has a stable denitration efficiency of 70%-85%. Vice Minister Zhang also asked Conch Group to take concrete steps to take concrete actions. All these things clearly show that cement can no longer be a "student" before the denitrification stage, but that it should be an "actor" on the stage.
As for the "script" used for the performance is "500" or "400" version, cement companies can proceed strictly and practically. The "400" version may be considered on the "stage" where densely populated areas and industrial projects are more geographically concentrated, and the "500" version may be considered first on the "stage" located in remote areas, and then there is room for action. .
It is relatively easy to implement the new standard for a new production line as if it were made on a fabric. It is more difficult for a large number of existing production lines to be renovated as old clothes. It takes more time and effort to think, and the time for planning is longer. Therefore, it is even more urgent to “rehearse†the time. The “2012 Second China Cement Denitrification Seminar†to be held in Hangzhou on March 17 is a suitable rehearsal site, with “sitesâ€, “directors†and “coachesâ€.
From the state's emphasis on the reduction of nitrogen oxides and the policies to be implemented, it will take too long for cement companies to “rehearse†before the denitrification stage, and it will be a matter of time before the stage. Apply a slogan - what are you waiting for? Act now!
