Preliminary study on profiles of VOC_S emitted from coking
Volatile organic compounds (VOC_S) from indigenous coking and surrounding the mechanized coking plant were determined by multi-bed adsorbent tube sampling followed by thermodesorption and GC/MSD detection. The concentration of TVOC reached as high as 1782.2μg/m~(3) in the emission from the indigenous coking. The result reveals that VOC_S are composed of aromatic compounds, alkanes, chlorinated compounds and terpenes. The aromatics are the main components and 75.63%、72.25% in the indigenous coking emissions and the surrounding out of mechanized coking plant, respectively. The relative ratios of BTEX indicate that profiles of VOC_S from coking are different from those emitted from motor vehicles.
