| Abstract: | The modified rate-based model for the simulation of catalytic distillation process is applied to simulate the pilot catalytic distillation process for the hydrolysis of methylacetate. The mass transfer coefficients for the catalyst packing in the reaction zone are calculated using the correlations regressed from experimental measurements and that for the stripping zone with Onta's correlations. The reaction rate is calculated on the macroscopic kineticcorrelation and measured effectiveness factor. The results are satisfactory as the compositionand temperature profiles along the column are concerned. |
