10.4 Balancing Calculated Diameters

Occasionally the calculated diameter at different points in the column will vary by a large factor. For example, for distillation of a vapor feed of ethanol and water, the calculated diameter at the top of the column was 3.7 times as large as the calculated diameter at the bottom of the column (Wankat, 2007a). For distillation of a liquid feed of acetic acid and water (water is more volatile), the calculated diameter at the bottom was 1.7 times the calculated diameter at the top (Wankat, 2007b).

Instead of building the entire column at the larger diameter, it may be possible to balance the column diameters. Equation (10-14) shows that the column diameter is directly proportional to the square root of the vapor ...
