Determination of mass transfer rates in wetted and non-wetted microporous membranes [PDF]
, 1992 The mass transfer resistance of microporous membranes placed between a gas and a liquid phase was studied for both wetted and non-wetted membranes. It was found that the mass transfer coefficient can be described according to the film model in which the ...

Gas—Liquid Mass Transfer Coefficient in Stirred Tank Reactors [PDF]
The Canadian Journal of Chemical Engineering, 2002 AbstractVolumetric gas—liquid mass transfer coefficient (kLa) data available in the literature for larger tanks (T = 0.39 m to 2.7 m) have been analyzed on the basis of relative dispersion parameter, N/Ncd. It was observed that at a given superficial gas velocity (VG), kLa values were approximately the same irrespective of geometric configuration (size
