In a determination of the effect of solute concentration on gas‐phase mass transfer rates carbon tetrachloride was vaporized at three different concentration levels in a short 4.0‐in.‐diameter column packed with 0.5‐in. Raschig rings. The experimental data indicate that previous mass transfer correlations should be modified to include a term ( P BM / P T ) 2/3 and that the Schmidt number should be evaluated at average film conditions. The correlation found is suitable for predicting gas‐phase mass transfer coefficients which can be combined with effective interfacial areas reported previously to obtain volumetric mass transfer coefficients for any gas‐liquid‐solute system.
