The Chinese government has also strengthened its control over mercury pollution and will control mercury pollution as one of the priorities of the “Twelfth Five-Year Plan†environmental protection work. Some of the most sensitive foreign chemical companies perceive the business opportunities and started the marketing promotion work in the early stage.
Ren Guoping, secretary-general of the Chinese Society of Environmental Sciences, said that research data shows that 80% of mercury is emitted to the atmosphere in the form of steam, which mainly comes from the burning of fossil fuels, especially coal. It is estimated that more than 40% of the world's anthropogenic mercury emissions come from burning coal. Coal-fired power plants are the largest source of atmospheric mercury emissions. Therefore, mercury pollution control in coal-fired power plants has become the focus of mercury emission reduction. The Chinese government attaches great importance to the control of mercury pollution. In 2009, 8 departments including the Ministry of Environmental Protection and the Ministry of Industry and Information Technology jointly issued the “Guidance Opinions on Strengthening the Prevention and Control of Heavy Metal Pollutionâ€. The Ministry of Environmental Protection is submitting the “Comprehensive Control Plan for Heavy Metal Pollution Prevention†approved by the State Council and is preparing In the "Twelfth Five-Year Plan" Regional Air Pollution Joint Prevention and Control Plan, all arrangements have been made for the control of atmospheric mercury pollution in coal-fired power plants. Zhang Huatian, director of the Science and Technology Division of the Department of Science and Technology of the Ministry of Environmental Protection, told reporters: “The Science and Technology Department of the Ministry of Environmental Protection will start the preparation of the best feasibility technical guidelines for pollution prevention in the industrial sector next year, including mercury pollution control technologies.â€
At present, the more mature mercury removal technology in the world is activated carbon adsorption technology and oxidation technology. On December 2, eight foreign chemical companies from the United States, Austria, Israel, and other countries collectively unveiled the 2010 Mercury Pollution and Control Technology Symposium, introduced their respective mercury removal technologies and products, and expressed their willingness to contribute mercury pollution to China. Control provides product and technical support.
Han Songqing, manager of public policy and affairs at American Polycom, said that in 2009 Coquia launched a series of products of calcium bromide and sodium bromide aimed at reducing mercury emissions from coal-fired power plants. Calcium bromide is an efficient and universal mercury removal agent that can be introduced at different stages of coal-fired power generation without causing corrosion problems. It can be used alone or in combination with an adsorbent, and it can also use existing desulfurization. , Denitrification and dust removal equipment to improve the efficiency of mercury removal, application is very flexible.
Liu Xin, a senior environmental engineer at Albemarle, also stated that brominated activated carbon injection and addition of bromide to coal is currently the most mature and effective commercial mercury removal technology in the United States. Albemarle has used this technology to run more than 40 operations in the United States. Demonstration project.
Shi Shiming, business development manager of Israel Chemical Group, said that the bromine-based Merquel mercury removal technology is an effective and practical mercury removal program, and its mercury removal efficiency can easily reach over 95%, and it can also be used for existing coal combustion. The system has no effect, is very safe and will not cause secondary pollution. Nalco Mobotec, Calgon Carbon and Norit also introduced the application and solutions of activated carbon in the removal of mercury from coal-fired power plants.
Zhang Junying, deputy director of the State Key Laboratory of Coal Combustion, Huazhong University of Science and Technology, said that the control of mercury pollution in coal-fired power plants is still in its infancy. The country has no mercury emission standards for mercury, and mature mercury removal technologies are still blank in China. Only a few scientific research units are doing research and development. Most of the mercury removal technologies abroad are developed for low-sulfur coals, and the sulfur content of coal in China is relatively high. Therefore, foreign technologies must be successfully applied to domestic coal-fired power plants, and they must be improved.
On December 2, the 2010 mercury pollution and control technology symposium sponsored by the Chinese Society of Environmental Sciences was held in Beijing. The participating experts agreed that mercury pollution has become a global environmental problem after the issue of climate change. The international community has paid more and more attention to the issue of mercury pollution. The UNEP Governing Council held its first meeting of the Intergovernmental Negotiating Committee in Stockholm, Sweden, in June 2010. It will hold its second meeting in Japan in January 2011. Negotiate on global mercury pollution control and will reach a binding international convention in 2013.
