✦ Synopsis

The effect of diffusivity on gas-side mass transfer coefficient was studied in an experimental bubble column. A fourteen-fold variation of diffusivity was obtained by using a variety of solutes and carrier gases. Both absorption and vaporization experiments were car&d ou< some&es for the same solute. The absorption experiments were unambiguously gas-film controlled.

The gas-side mass transfer coefficient varies as 0.5 power of the di&sivity under similar hydrodynamic conditions. Schmidt number is most unlikely to be the pertinent variable. It is also likely that the gas-side mass transfer coefficient varies as 0.33 power of the submergence and 0.75 power of the gas flow rate.
