This is well in line with the MOC criterion in Sec. 8.2.12.

Average bed pressure drop calculation

Most methods for pressure drop calculation assume the column handles a nonfoaming mixture. Therefore, they do not strictly apply to the high-pressure column in this example, where systems do show a tendency to foam. The only published method that applies for these conditions is Strigle's [15; Eq. (8.29)]. This method was used earlier in this example to check compliance with the maximum pressure drop criterion. Here it is used to calculate the average bed pressure drop.
