Abstract:

Mobile passive differential optical absorption spectroscopy (DOAS) was used for the remote sensing of the emission flux from different systems of a steel factory. Correlation matrix of the absorption cross sections used for DOAS retrievals. Vertical column density was retrieved by this system, combined with the meteorological wind field and car speed information, the emission of SO2 and NO2 in the area was estimated. The result showed the average value of the flux of SO2 and NO2 in the rolling and smelting system was 149kg/h and 372kg/h. The average value of the flux of SO2 and NO2 in the coking system was 260kg/h and 286kg/h. The average value of the flux of SO2 and NO2 in the power system was 21kg/h and 26kg/h. The average value of the flux of SO2 and NO2 in the roasting system was 64kg/h and 79kg/h. The average value of the flux of SO2 and NO2 in the sintering system was 34kg/h and 99kg/h.
