Progress in research on structured packing in high pressure application is introduced. The effect of pressure on the physical properties, hydrodynamic behavior and mass transfer in packed tower is reviewed and discussed. The cause of packing efficiency loss and “efficiency hump” at high-pressure distillation is summarized and analyzed on the basis of the most recently experimental results. The validity of various mass transfer models from the literature for estimating structured packing efficiency at high-pressure condition is evaluated.
