Gas holdups and volumetric mass transfer coefficients k L a are studied in a bubble column of 0.095 m dia. with 50 different gas‐liquid systems comprising pure and mixed organic liquids and various gases. The gas holdups measured in pure organic liquids can be represented by existing correlations but the values in liquid mixtures are high. On the other hand, all mass transfer coefficients can be correlated uniformly by a new dimensionless equation, with 13.3% mean error.
