The basic theory and application research progress on distillation for rotating bed are introduced and the distillation research status is clarified.Problems that might occur in the rotating bed industrialization are analyzed and the improved measures are proposed.And the promising application for rotating bed in chemical industry is described.The results show that rotating bed is a new kind of gas-liquid process intensification distillation equipment and its theoretical tower plate height is decreased by 1

2

orders of magnitude comparing with the traditional distillation tower.The distillation technology in high gravity condition will be widely applied.
