【 摘 要 】

On the basis of investigating the production process of petrochemical enterprises, The components of non-methane volatile organic compounds (NMVOCs) of each emission link in two typical petrochemical enterprises in Hainan Province using adsorption tube adsorption-thermal desorption/gas chromatography were measured and studied. The sampling analysis was conducted on the wastewater treatment and organic waste gas collection device, isomerization device, product refining deodorization device, desulfurization and denitrification device, as well as the unorganized (ambient) air around the factory. Based on this, the NMVOCs component emission inventory and ozone formation potential were studied. The results show that the emission mass concentration of NMVOCs from the above-mentioned petrochemical enterprises in Hainan Province was rather high, at 33-627.9 mg/m3. A total of 21 types of NMVOCs were quantified, of which acetaldehyde, methanol and acetone were the three dominant substances. In addition, as major categories of photochemical pollutants in petrochemical enterprises, aromatic hydrocarbons and olefins were mainly shown as xylene, propylene and butane.
