Currently, flue gas dust removal, desulfurization, denitrification are the three business segments in air pollution control, the survey statistics of Commercial Industrial Research Institute shows that in 2015, China's desulfurization and denitration industry needs scale over 90 billion RMB, of which the new market capacity is more than 400 billion, and the market of transformation capacity is more than 50 billion RMB, also with the national standards of air pollution regulations becoming more stringent, the next 5--10 years will be the key period for China's air pollution control, the increase of market capacity will continue to be at about 10% .

 

Premier Li Keqiang in his government work report made, 50,000 units of small coal-fired boilers will be eliminated in the end of "12th Five-Year", the transformation desulfurization of 15 million kilowatts of the coal-fired power plant will be promoted, and denitrification transformation of 130 million kilowatts, 180 million kilowatts dust transformation. According to the State Council issued the "2014--2015 Annual Energy Saving And Emission Reduction Carbon Development Action Plan", during the remainder period of  "12th Five-Year", the desulfurization and denitrification projects will be continually promoted, and denitrification transformation of 300 million kilowatts coal-fired units should be done, 250 million kilowatts burning coal flue gas unit should remove bypass, 40,000 square meters of steel sintering machine to install desulphurization facilities, 600 million tons of clinker production capacity of cement production line installed denitration facilities.

Wherein, the first, second and third column respectively on behalf of desulfurization and denitration market size, the new market capacity and the transformation market capacity, the unit is all one hundred million RMB.

 

SCR denitration system is widely recognized as the most effective, universal application of denitrification technology. In the current background of full swing flue gas denitrification project settings and renovation project, tungsten trioxide denitration catalyst as the core technology of SCR system, its application prospect is very bright. Tungsten trioxide mainly plays the roles of anti-sulfide, poisoning resistance, and enhance the ability of anti-sintering carrier itself ect. in the denitration catalyst; in addition, due to the cheap price of tungsten trioxide (compared to Au, Pt and other precious metals), tungsten trioxide denitration catalyst as a sharp weapon is expected to become the "Blue-Eyed Boy" of air pollution governance.
