Packed-Bed Column Diameter

The value of the packing factor, Fp, is obtained from Table 7.2 or from vendors.

After calculating the Abscissa value, a corresponding Ordinate (Yaxis) value may be determined from the flooding curve. The Ordinate may also be calculated using the following equation  

As a rule of thumb, the diameter of the column should be at least 15 times the size of the packing used in the column. If this is not the case, the column diameter should be recalculated using a smaller-diameter packing [10]. The superficial liquid flow rate entering the absorber, Lf (Ib/h-ft ) based on the cross-sectional, is
