MASS TRANSFER COEFFICIENTS BETWEEN GAS AND LIQUID PHASES IN PACKED COLUMNS

Abstract

enhances the probability of the bubble coalescence and makes bubble larger. On the other hand, in the present study the dimention of the apparatus is far larger than that of the distributor and the depth of the liquids is shallow. Therefore, the probability of the bubble coalescence over the distributor is less than that of the Houghton et al.'s case, because the circulation of the liquid in the apparatus makes bubbles easy to apart each other. This fact is recognized when the porous plate distributor is used for liquid of group A and C in the bubble column with continuous liquid flow.
