摘　　要：选用 6种代表性物系对陶瓷板波纹和不锈钢丝网规整填料进行全回流精馏实验 ,考察Marangoni效应对规整填料液体流动分布及传质的影响 .结果表明 :对纯有机体系 ,Marangoni效应影响较小 ;而对有机物的水溶液 。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.
