Characterization of 58 Species Non-Methane Hydrocarbons from a Typical Coke Production Plant in Northern China

Abstract:

The profile of 58 species non-methane hydrocarbons (NMHCs) emissions from a typical coke production plant in northern China was studied. Source samples were taken using a dilution chamber system and were quantified by a gas chromatography/mass spectrometry (GC/MS) system. Based on the measurement of source profiles, aromatic hydrocarbons were found in highest concentration (48.5%), followed by alkanes (42.9%) and alkenes (8.6%), respectively. The emission of C₆-C₇ species took the largest proportion of the NMHCs, toluene and n-hexane were primary species, accounted for 27.4% and 25.1% of total NMHCs. The OH loss rate of NMHCs were estimated, indicated that alkenes (46.5%) played the most important role in L_OH, followed by aromatic hydrocarbons (34.3%) and alkanes (19.2%). The top 5 species in L_OH were: 1-butylene, toluene, n-hexane, trans-2-butene and cis-2-pentene.
