The Yangzi Petrochemical denitrification project is functioning on existing facilities. After fully investigating some domestic denitrification enterprises, according to the site environment of Yangzi Petrochemical Thermal Power Plant, it was decided to use a low-nitrogen burner, selective non-catalytic reduction method, selective catalytic reduction. The triple denitrification combined process procedure, such as the reaction method, begins with the use of a low-nitrogen burner to reduce the amount of combustion nitrides, and then performs a reduction reaction to the catalysts that have generated nitrides to achieve a reduction in the fractionation, and finally reduces the nitrogen oxides to Environmentally stable air components that are completely harmless to the environment reduce the content of nitrogen oxides in flue gas to the national standard of 100 mg/cubic meter or less in the eastern part of China to achieve environmental protection.
The project was formally started on the No. 2 furnace in the thermal power plant on November 1, 2011, and achieved successful experience. According to the characteristics of continuous operation of chemical production, Yangzi Petrochemical has formulated a plan for renovating the shutdown furnaces, which not only guarantees the need for chemical power production and the use of steam, but also completes the transformation of denitrification projects according to the plan to achieve emission reduction targets. The single largest No. 9 furnace of this time completed the denitrification reform and successfully connected to the grid, which has the effect of reducing the environmental impact of the emissions and also creating the conditions for stabilizing the steam and electricity balance of the winter chemical production equipment. According to the arrangement, the denitration and transformation of the remaining two boilers will be completed in early 2014. At that time, Yangzi Petrochemical will become the first company in the system to complete the transformation of thermal and electric denitrification, and will contribute to Sinopec's efforts to reduce nitrogen oxide emissions.
It is reported that the total amount of flue gas denitrification and emission reduction has been linked to the development of enterprises and has become a constraint factor for sustainable development.
The smooth progress of the denitrification transformation of Jiuhua Power Generation went smoothly On November 30th, the denitration reactor of the second unit of the Jiuhua Power Generation Corporation, the denitrification reactor of #1 furnace, was successfully capped. The installation of the denitrification retrofitting project was completed and it was about to enter the commissioning stage. The boiler flue gas denitrification transformation is the company's key technological transformation project in 2013, and it is also an environmental protection project that responds to the national call and promotes energy conservation and emission reduction. After the project is completed and put into production, the company can reduce its annual nitrogen oxide emissions by more than 5,000 tons.
Yanshan Petrochemical's boiler flue gas denitrification test project was completed. On November 15th, Yanshan Petrochemical's boiler flue gas denitrification test project was successfully completed as a key environmental protection project in the “Clearwater Blue Sky†project of Sinopec Group Company, and a hot state commissioning was conducted on the 18th. The newly installed six low-nitrogen burners completed the first manual ignition test.
