The absorption of oxygen from air into water has been measured in vertical tubes with swirl bodies in the inlet part. The tubes were of 70 mm I.D. and of height H with diameter ratio H/D ≦ 22. The two-phase flow was directed upward. Superficial gas velocity was ωG = 10 to 35 m s-1 and specific liquid load QLE = 13 to 80 m3m-2h-1. Values of the liquid-side mass transfer coefficient were determined as ratios of experimental values of volumetric mass transfer coefficient and specific interfacial areas, which were measured earlier. Murphree efficiencies were obtained with experimentally determined Peclet numbers considering the real mixing conditions of the liquid phase.
