The present work reports a series of' experimental measurements of liquid-side mass transfer coefficient for slugs rising in liquids with viscosities in the range 0.9 x IO-'-0.14 Pas. Three column diameters were used (19,32 and 52 mm) and slugs with values of L/D up to 38 were studied. The data obta
