| Abstract: | Pressure loss, holdup and liquid distribution were measured for a standard 10 mm glass Raschig ring packing. The first two characteristics showed gener However, the actual holdup values and the loading and flooding zones were significantly lower than those expected for nominally similar packing. These of packing which caused variations in mass transfer coefficients due to the existence of different dry or inactive areas in nominally similar packings.The flow distribution was shown to be statistical in nature in agreement with the rivulet flow model. At the top of the packing, the radial distributio of 12 – 15 column diameters, the liquid flow distribution became constant and was predominantly at the wall. The main flow in the bulk of the packing distribution. Any increase in liquid flow was carried in existing rivulets since the number density increased very slightly with increasing liquid flow |
