【 摘 要 】

References(28)Cited-By(4)In this research work, the effect of pulse intensity, flow rate of disperse and continuous phases on volumetric mass transfer coefficients of two phases along the height of pulsed sieve-plate column have been studied. Two chemical systems, toluene–acetone–water and normal butyl acetate-acetone–water, were used. The deviation between experimental and predicted values from equations, which have been proposed by other researchers is considerable. A correlation for predicting enhancement factor of diffusion coefficient of mass transfer coefficients has been achieved and the comparison between experimental data and predicted values are in very good agreement. Finally, the proposed equation is used for calculating height of the column.
