Liangang Group Co., Ltd. is located in Loudi City, central Hunan Province. It has been listed as one of the top 500 industrial enterprises for several consecutive years and is one of the 300 industrial enterprises supported by the state for development. Lianyungang Iron and Steel vigorously develops circular economy, focusing on both scientific energy conservation and optimized energy use. Two sets of ammonia escape online monitoring systems from Shengnuo Instrument have been introduced. Under the guidance, installation, debugging, and training of Shengnuo instrument engineers, the equipment has been officially put into operation.
Hunan LiangangThe desulfurization and denitrification project for coke oven flue gas adopts“Ammonia desulfurization process+Selective Non Catalytic Reduction (SNCR) Denitrification Process ",Require ammonia escape emission concentration to be below 6ppm to achieve environmental compliance.The two sets of ammonia escape online monitoring systems installed this time will directly serve the process optimization and emission compliance monitoring links.
Ammonia desulfurization process: using liquid ammonia or ammonia water as absorbents, reacting with sulfur dioxide to produce ammonium sulfite and ammonium bisulfite, and then obtaining ammonium sulfate fertilizer through oxidation and other steps. The advantages of this process are high desulfurization efficiency, comprehensive utilization of by-products, and no secondary pollution.
Selective Non Catalytic Reduction (SNCR) Denitrification Process: A reducing agent (such as urea, ammonia water, etc.) is sprayed into the high-temperature zone of the furnace. In the absence of a catalyst, the reducing agent reacts with nitrogen oxides to produce nitrogen gas and water. This process has low investment cost and simple operation.
Our engineers customize the sampling point layout plan based on the on-site working conditions of Liangang, optimize the flange interface and protective component configuration.Complete optical path calibration, parameter calibration, and equipment debugging, and conduct operation and maintenance training simultaneously.The successful operation of the Liangang project marks the further maturity of Shengnuo Instrument's ammonia escape monitoring technology in the steel industry, helping enterprises achieve ultra-low emission targets.
