At the China Cement Association’s “Seminar on China Cement-Related Industries Development and Innovation of Cement Marketing Modelsâ€, an informed source interviewed by the China Securities Journal said that the amendments to the nitrogen oxide emission standards for cement companies have been formally established. The new standard is not It will be more stringent than the current strictest 500 mg/standard cubic meter in the world, and cement companies participating in emission reduction will receive financial subsidies. The National Environmental Protection "Twelfth Five-Year Plan" pointed out that during the "Twelfth Five-Year Plan" period, nitrogen oxides emissions will be reduced by 10%. It is proposed that the new dry-process cement kiln should carry out low-nitrogen combustion technological transformation and the new cement production line should be installed with low efficiency. 60% of denitrification facilities. The source pointed out that this year has entered the second year of the "Twelfth Five-Year Plan". Even if it is introduced at the end of this year, it will only have three years to complete this emission reduction target. From this point of view, it is not ruled out that the newly revised emission standards may be introduced in the near future. It is understood that the Ministry of Environmental Protection will formally start formulating nitrogen oxide emission standards for the cement industry this month. According to reports, in response to the revision of the new standard, the Ministry of Environmental Protection has already communicated and communicated with some companies, discussed the technical roadmap for nitrogen oxide emission reductions, listened to the opinions of the companies, and may then communicate again. Previously there were rumors that the emission standards under study were 300 mg/standard cubic meter and 400 mg/standard cubic meter, and the person told the China Securities Journal that the newly revised national standard will not be higher than the current one. The highest international level, ie no more than 500 mg/standard cubic meter. It is understood that the current nitrogen oxide emission standards for the cement industry in China are 800 mg/standard cubic meter. The most stringent NOx emission limit in international standards is Germany. When the secondary fuel replacement rate is ≤ 60%, the NOx emission concentration must not exceed 500 mg/standard cubic meter; the secondary fuel replacement rate is more than 60%. At the time, the emission concentration must not exceed 200 mg/standard cubic meter. The implementation of 500 mg/ standard cubic meter is also European countries such as Switzerland and Austria. The US standard is 900 mg/standard cubic meter. However, the source also pointed out that the revision of the new standard still faces many difficulties. First, the currently accepted denitrification technologies in the industry include Selective Catalytic Reduction (SCR) and Non-Selective Absorption and Reduction (SNCR). However, both technologies are not mature enough, and they still need time to improve and improve. They need to be applied in practice. In the process of continuous verification and improvement, monitoring technology has yet to be improved. How to effectively monitor cement companies across the country is an urgent issue to be solved. The source also disclosed that the Ministry of Environmental Protection and the Ministry of Finance had already communicated, similar to the previous policy of subsidies for emission reductions by power companies, and the Ministry of Finance will subsidize emission reductions for cement companies. According to the consistent practice of the Ministry of Finance, special funds are generally issued to local governments first, and then issued by local governments to local enterprises. It is understood that before the power industry has implemented new emission standards, thermal power plant nitrogen oxide emission standards for 100 mg / standard cubic meters. On November 30 last year, the National Development and Reform Commission promulgated the "State adopts comprehensive measures to regulate coal and electricity prices," stating clearly that since December 1, 2011, the pilot denitrification tariff policy has been applied to coal-fired power plants that have installed and operated denitrification devices. 0.8 cents per kWh increase to compensate for the increased cost of denitrification. Industry sources pointed out that the emission standards for nitrogen oxides are not as high as possible. Denitrification requires a large amount of catalyst ammonia, and the production of ammonia requires a large amount of coal, and mass production of ammonia also causes environmental pollution. In addition, ammonia may cause new pollution during transportation. The ammonia slip caused by the excessive use of ammonia in the denitrification process will also cause new pollution. Glycol Phenyl Ether ( pph), is a slow evaporating glycol ether. The substance is a clear, slightly yellow liquid and it`s odor is low and faint. It is very hydrophobic, while it`s molecular weight is heavier than other similar solvents. These distinctive qualities make Glycol Ether PPH an excellent choice for phenolic linings and coatings as well as a coalescent for acrylic- based latexes.
