April 25, Zhenhai Refining and Ethylene Cracking Plant Large-scale double-furnace gas cracking furnace environmental protection pilot to enhance the management project - Flue gas denitrification system successfully put into use, cracking furnace emissions of nitrogen oxides decreased by more than 40%, becoming the first Successful use of ethylene cracking furnace enterprises. After use, nitrogen oxide emission concentration control in 70 mg / cubic meters, far better than the national requirements in July this year to reach 100 mg / cubic meter.
Nitrogen oxide emissions are the focus of air pollution control. July 1, the state will implement a new standard of flue gas emissions, sensitive areas of heating furnace nitrogen oxide emissions required less than 100 mg / cubic meter. The country's ethylene cracking furnace are basically through the transformation to meet the new requirements. At present the industry is the means of transformation of ethylene cracking furnace mouth, but the program is not mature.
Zhenhai Refining and Chemical Ethylene cracking double furnace gas cracking furnace is a new equipment, at the beginning of the construction, Zhenhai Refining and Chemical Research Institute and other units to try to refinery catalytic denitrification technology used in ethylene plant, environmental protection pilot to enhance governance projects and Gas cracking furnace construction. In June 2016, the gas cracking furnace was put into use, and the environmental protection pilot project was completed. In early 2017, the flue gas denitrification system was completed.
Ethylene cracking furnace flue gas denitrification technology by the China Petrochemical Engineering Construction Company (SEI) and Fushun Petrochemical Research Institute jointly developed. The nitrogen oxides in the flue gas are converted into nitrogen and water by the catalytic reduction of the catalyst bed into the convective flue gas, so as to reduce the nitrogen oxides in the flue gas.
