“China’s total SO2 emissions in 2005 ranked first in the world.†At a press conference held by the Information Office of the State Council recently, Li Xinmin, deputy director of the Department of Pollution Control of the State Environmental Protection Administration pointed out that last year, China’s total sulfur dioxide emissions amounted to 25.49 million. Tons, an increase of 27% over 2000.
According to the “Eleventh Five-Year Plan†of the National Environmental Protection, the total amount of sulfur dioxide emissions will be reduced by 10% by 2010. The State Environmental Protection Administration believes that in accordance with the provinces and six major power companies desulfurization plan, the existing generating units will add 118 million kilowatts of desulfurization capacity during the “Eleventh Five-Year Plan†period, forming a desulfurization capacity of 4.44 million tons; in the acid rain control plan, steel, non-ferrous metals There are 33 key management projects in such industries, and the estimated reduction capacity is 500,000 tons. The above two items can form a total capacity of 4.9 million tons, and basically achieve the goal of emission reduction.
Despite this, Teng Jing, deputy secretary-general of the China Environmental Protection Industry Association, said that to achieve emission reduction, there are still bottlenecks that need to be broken.
It is difficult for high-priced equipment companies
Although starting from 2003, China has accelerated its efforts to control sulphur dioxide emissions from thermal power plants. However, the domestic desulphurization equipment industry lacks a series of products due to its late start and imperfect development. At present, the low localization rate of equipment has seriously hampered the progress of thermal desulfurization in China.
It is understood that the current limestone-gypsum wet desulfurization process technology commonly used by large-scale power plants is mostly imported from abroad or purchased key equipment and assembled, and every project that is launched must pay a high patent fee to the technical side. The large investment and difficulties in technical selection have given the power plant a strong reason for delay.
“We have been conducting comparison and selection of desulfurization facilities. Most of the current technology is imported from abroad and the price is very high.†Ma Yongfeng, assistant to the president of Ordos Power Company in Inner Mongolia, said helplessly. In accordance with relevant state regulations, their desulphurization facilities should be put into operation in March this year, and the high prices of imported desulfurization equipment have made them prohibitively desulphurization facilities.
Experts believe that the low domestic production rate of desulphurization equipment leads to excessive prices, and that large and medium-sized thermal power plants desperately need more than 100 million yuan for desulphurization equipment. According to calculations, the price of domestic equipment is only equivalent to half or two-thirds of the price of imported equipment. However, currently there are few models available for selection, and the operation of equipment is not stable enough.
China's dependence on desulfurization technology is relatively high abroad, and there are many domestic companies to introduce a foreign company technology phenomenon. Nearly 100 large and small desulphurization companies in China, large units basically use foreign desulfurization technology, under normal circumstances, the desulfurization project of 200 MW units needs to pay more than 3 million yuan of technical fees for foreign companies. At present, nearly 60% of the desulfurization facilities built in China have been imported from abroad. Domestic companies are only responsible for civil engineering and installation. In general, the cost of using imported equipment is on average 30% higher than the cost of using domestic equipment.
Teng Jing believes that domestic desulfurization equipment lacks independent intellectual property rights, and the proportion of domestic desulphurization equipment is not high, which not only restricts the development of China's environmental protection industry, but also is not conducive to advancing China's mechanical and electrical industry technological progress and industrial upgrading. The profits of the enterprise are lost as the technical use fee is paid.
Desulfurization market competition disorder
Teng Jing also pointed out that the policy of regulating the environmental protection industry is not sound enough to regulate industry behavior. The desulfurization market is very large, and once it was very profitable, so a large number of companies are influxing, and from a few households to even dozens or even nearly 100 homes. Everyone competed to reduce the price of vicious competition, the price dropped from 300-400 yuan per kilowatt-hour to the current 90 yuan. The result of price competition is that quality cannot be guaranteed and desulphurization emissions do not meet the standards.
At the same time, because of the policy of “whoever polls and govern,†polluting companies can bid for themselves. He has transformed into an “Uncleâ€, and the lowest cost can be found by pushing down the prices. The effect of governance can be imagined. The vicious cycle makes it difficult to control pollution.
It is understood that in 2003, China introduced the “Feeding Power Plant Charge Standards†to substantially increase the sulfur dioxide emissions charging standards. Surprisingly, these desulphurization equipments that are idle and large-scale power plants have not only been exempted from sewage charges, but have enjoyed the government's subsidies for desulfurization.
The person in charge of the environmental protection department of the Changshu Port thermal power plant told the reporter that the EPA would check it from time to time, but each time it comes, it will give a greeting to the company in advance and the desulfurization equipment can be operated within one hour. Because the EPA did not install an on-line monitor in the power plant and could not collect relevant data on the desulfurization treatment in real time, it could not understand the SO2 emission concentration of the company. Therefore, the power plant not only does not need to pay the SO2 emission charge. On the contrary, according to the state's regulations on desulfurization subsidies, the power plant can enjoy a “clean†subsidy of 1.5 cents each time it generates electricity.
According to Teng Jing’s introduction, some places are relatively strict in implementation and “no rabbits are not hawkedâ€. Subsidies are only seen after the desulfurization machine is actually operating. However, in reality, online monitoring is not sound and it is inevitable that there will be “stolen parkingâ€. .
Costly equipment and market disruption restrict SO2 emission reduction
Teng Jing pointed out that the policy of regulating the environmental protection industry is not sound enough to regulate industry behavior. The desulfurization market is very large, and once it was very profitable, so a large number of companies flooded in. Everyone competed to suppress vicious competition, and the price dropped from 300-400 yuan per kilowatt-hour to 90 yuan. The result of price competition is that quality cannot be guaranteed and desulphurization emissions do not meet the standards.
