In a series of two papers the results of investigating the mass transfer characteristics of two gas‐liquid reciprocating plate columns of the Karr type by different methods are presented. The subject of the first part is a study of the liquid phase volumetric mass transfer coefficient, k L a , while the second part deals with the interfacial area. The volumetric coefficient k L a was investigated using the sulphite method, the pure physical absorption of oxygen, and a dynamic method under culture conditions, the second of these three methods being the most favorable. Very good agreement among these methods was found. Generally, k L a increased with increasing vibration intensity, superficial gas velocity, and the number of perforated plates. Liquid‐phase properties appeared to affect k L a only slightly. The coefficient k L a was correlated in terms of the maximum power consumption and the superficial gas velocity:\documentclass{article}\pagestyle{empty}\begin{document}$$ k_L a = 0.467 \cdot P_{G.m}^{0.25} \cdot U_G^{0.6} $$\end{document}
