Abstract：
The performance of mass transfer and hydrodynamic characteristics of three types of rdered packings, i.e., copper gauze BX, ceramic BY and stainless steel Mellapak, and a random acking of Dg25 modified IMTP were tested in a distitlation column of 300 mm inside diameter. A imple pressure-drop formula for the three types of ordered packings has been obtained from bout 200 experimental data points. Extensive experimental investigation was Performed to llustrate the effects of vapor rate, pressure and reflux ratio on the performance of the ackings.
