| Abstract: | To investigate the influence of Marangoni effect on liquid flow and its distribution as well as separation efficiency of structured packing, binary distillation experiments were carried out at total reflux using six typical systems for ceramic corrugated sheet and stainless steel gauze structured packing.It was shown that the influence of Marangoni effect was small for pure organic systems.However,for aqueous organic systems,hydraulics and mass transfer of structured packing were both strongly influenced by Marangoni effect. |

| Keywords: | structured packing surface tension Marangoni effect mass transfer |
