This yields the necessary speciated VOCs emission data to be used to test the photochemical reaction mechanisms. Three photochemical reaction mechanisms, CBM-IV, RADM2, and SAPRC, were utilized to simulate the influence of emission characteristics on ozone formation due to the industrial park emissions. The main variables including VOC/NOx concentration ratios, photolysis rate, and temperature, are used to test the variation of ozone formation. According to the results, the hydrocarbon compounds emitted from the south Taiwan industrial park reveal a characteristic proportion of propane (32.6%), ethylene (7.3%), styrene (5.3%), and so on. Based on the emission situation of testing cases, the simulation by SAPRC revealed the highest maximum ozone concentration, and RADM2 the lowest one. The difference is mainly due to the different lumping method of propane in the chemical mechanisms. |
