Simulation of the Biofiltration of Sulfur Compounds: Effect of the Partition Coefficients

The effect of the partition coefficient on simulation operation a biotrickling filter treating mixture sulfur compounds was analyzed to evaluate pertinence using Henry’s law in determining its removal capacity. analysis consisted that bio-oxides hydrogen sulfide (H2S), dimethyl (DMS), methyl mercaptan (MM) and disulfide (DMDS) different types models for coefficient: pure water, adjusted from experimental data, mixed model (Extended UNIQUAC) semi-empirical two-parameters. simulations were compared with data. It observed water could produce significant deviations empirical data due liquid phase not being water. two-parameter better fits similar results extended UNIQUAC model, lower calculation cost necessary parameter amount. shows can considerably improve accuracy where complex interactions are present.
