Yêu cầu trực tuyến →— The spray absorption desulfurization device is shown in Fig 7 As can be seen C 3 H 6 and NH 3 are reacted through valves 3−1 and 3−2 located at the bottom of the reaction tower 1 The excess NH 3 after the reaction is removed by two cycles of H 2 SO 4 and the gas such as acrylonitrile is absorbed in the top absorption tower by
Yêu cầu trực tuyến →— U f = Vapor velocity that is sufficient to suspend liquid droplets Vapor velocity greater than U f can be associated with entrainment flooding length time 1 V = molar flowrate of the gaseous stream mol time 1 Note that many of the parameters can have different values for different stages in the column
Yêu cầu trực tuyến →— atomized droplets in the FGD tower The results can be used to guide the optimization of droplets spray evaporation under practical operating conditions in the desulfurization tower 2 Model and Methods The physical model is shown in Fig 1 The height of the FGD tower is m and the diameter is m The
— desulfurization tower slurry foam was diluted with deionized water and observed after standing The foam was divided into two layers The upper layer was oil formed bubbles and the wide strong absorption peak existed between 3300 and 2900 Figure 3 Infrared spectra of the oily matter in the carbon tetrachloride solution after
Yêu cầu trực tuyến →Most of the coal oil and natural gas produced in the world are used as fuels and a small part is used as a chemical feedstock Undesulfurized coal and oil in the combustion process will produce a large number of sulfur oxides SOx serious harm to human health and environmental damage The unpurified natural gas containing hydrogen sulfide H2S is
Yêu cầu trực tuyến →— Abstract Based on problem diagnosis and sample analysis of a typical case of wet flue gas desulfurization WFGD slurry foaming this study deeply explored and traced the slurry foaming origins Above all the main causation of this accident was the accident slurry discharged with the absorber slurry to cause chemical oxygen demand COD of
