Experiments are conducted to reveal and compare the effects of surface tension gradients on the mass transfer performance of columns packed re -spectively with three types of packing materials. The results obtained show that surface tension gradients have evident influence on the three types of packings
though in different extents. Theoretical studies of the effect of surface tension gradients on the wetted area of packing
leads to a new Ma-rangoni number
i. e. which may serve to explain the influence of surface tension gradients. The relationship between the wetted area and St has also been determined quantitatively.
