| Abstract: | Two mechanisms are presented and employed to simulate the solar irradiation of an expanding plume consisting of SO₂, NO, NO₂, CO, and olefin at initial concentrations expected in power plant emissions. The first mechanism is a conventional atmospheric photochemical model consisting of 30-species while the second is a 15-species surrogate which accurately reproduces the results obtained with the first mechanism and does so with a 60 to 70% savings in execution time. SO₂ conversion rates in the range of 0.05 to 6% hr⁻¹ are predicted and the oxidation mechanism is found to be controlled by the HO-SO₂ and O-SO₂ reactions with the latter significantly contributing to H₂SO₄ formation in the early stages of the plume life. |
