Abstract :
In this paper, we focus on the properties of simultaneous removal of multi-pollutant (ozone oxidation and chemical absorption). The oxidation process is modeled employing "full" chemistry and simulated in a perfectly stirred reactor (PSR). For the simulated flue gas stream, the volume fraction of NO2, NO3, N2O5, SO2 and SO3 are 1.48E-4, 1.29E-4, 2.1E-5, 1.6E-3 and 5.8E-7 at the outlet of reactor, respectively. The results compare and show good agreement with earlier experimental findings. The absorption process is analyzed by means of gas-liquid-solid equilibrium theory, chemical equilibrium theory and electro neutrality principle. The results obtained using the analysis shows good agreement with the simulated results employing chemical thermodynamic equilibrium and Gibbs energy minimization theory.
