The waste gas treatment industry is one of the key points for the development of the environmental protection industry during the “Twelfth Five-Year Plan†period. In particular, as the country includes nitrogen oxides as a total atmospheric emission control index, denitrification will become the biggest highlight of the “Twelfth Five-Year Plan†exhaust gas treatment.
Denitrification: Five-year investment of 200 billion yuan China's nitrogen oxide emissions are mainly concentrated in thermal power plants, and during the “Twelfth Five-Year Plan†period, denitrification is dominated by power plants. According to the emission limits of the “Emission Standards for Air Pollutants for Thermal Power Plants (Second Consultation Draft)â€, by 2015, the newly added flue gas denitrification capacity is 817 million kilowatts, which requires a total investment of 195.0 billion yuan for denitrification. According to relevant sources, the "Emission Standard for Air Pollutants from Thermal Power Plants (final draft)" will be released at the end of August.
At present, there are three denitrification methods used in thermal power plants: low-nitrogen combustion denitrification, selective catalytic reduction (SCR) denitrification, and non-selective catalytic reduction (SNCR) denitrification. The “Technical Policy for Prevention and Control of Thermal Power Nitrogen Oxides†uses low-nitrogen combustion technology as the technology of choice for controlling nitrogen oxides in coal-fired power plants, supplemented by flue gas denitrification facilities. The efficiency of denitrification in the back-end SNCR is low. In the future, denitrification will be mainly based on low-nitrogen combustion technology and SCR. The core device of the SCR back-end denitration system is a catalyst, which accounts for 30-40% of the total cost of denitration equipment, and has a long life span. Highly active catalysts determine the efficiency of denitrification, and companies that have achieved breakthroughs in catalyst technology have an advantage.
Since thermal power plants are generally in a profitable position, the country will use economic levers to promote the “denolytic denitrification†of the power industry, and promote the development of denitrification industry in thermal power plants through the tariff subsidy policy. The market generally expects the denitrification subsidies to be in the range of 1-1.5 cents/degree, but there is great uncertainty in the introduction of supporting electricity price subsidy policies during the year.
The front-end market for denitrification is bullish on Longyuan Technology, and the back-end market is recommended to focus on Jiulong Electric Power, a catalyst for technological breakthroughs, Huaguang shares that have been involved in the catalyst, and Yongda Environmental Protection, and potential suppliers of catalyst carriers, Annada and Lililian.
Off*: It is worth noting that the steel industry will become the focus of the market during the 12th Five-Year Plan period. According to statistics, in 2010, the SO2 emission of sintering flue gas in the steel industry reached 1.27 million tons. The Changjiang Securities Research Report pointed out that the Ministry of Environmental Protection is working on a new steel industry emission standard, which requires domestic steel mills to force the dismantling of the equipment, and that steel mills that do not lift off equipment will stop all new projects.
At present, the total number of sintering machines in the iron and steel industry in China is 1,000, and only 10% to 20% of the equipment has been installed, and 1/3 of them are not operating properly. Assuming that during the “Twelfth Five-Year Plan†period, all the stock sinter machines will be installed to remove the equipment. It is expected that the market capacity of the steel mills will be 160-200 billion yuan.
In addition to steel, there are industries such as cement, ceramics, rare earths, and flat glass that have (proposed) introduced new emission standards, which in turn will bring about demand for equipment reform. It is expected that the non-electric denitrification market will be at least 20 billion yuan during the “12th Five-Year Plan†period. Yongqing Environmental Protection has a stronger competitive edge in the non-electricity market.
The future off-market of the power industry is mainly focused on the reconstruction of newly-built thermal power units and existing thermal power off-sites. It is estimated that the annual average market size of power off equipment during the “12th Five-Year Plan†period will be around RMB 13 billion.
Dust removal: The benefit of the bag filter is currently close to 100%. The dust removal market during the "12th Five Year Plan" has limited growth. However, the “Emission Standard of Air Pollutants for Thermal Power Plants (Second Polling Draft)†changed the 50 mg/m3 emission limit of soot from the previous 50 mg/m3, making the existing electrostatic precipitators in coal-fired power plants unable to fully satisfy the requirements. Claim.
The bag filter can reach the standard level in the dust removal efficiency, but the use rate of bag filter in our power plant is less than 10%. As the bottleneck filter industry has achieved a breakthrough in the bottleneck high-temperature filter process and the localization rate has gradually increased, it can be expected that the bag filter will gradually replace the electrostatic precipitator during the “12th Five Year Plan†period. High-temperature filter materials will fully benefit from the changes in product structure and focus on three-dimensional filaments. According to Huachuang Securities, the total capacity of the high-temperature filter stock market and the stock replacement market during the “12th Five-Year Plan†totaled about 7 billion yuan.
