A typical capacity diagram or operating window is illustrated in Figure 12.14 based on the capacity guidelines, although specific applications warrant different capacity limits.

The capacity diagrams developed by Schmidt [9] are still used as practical working diagrams today. A valuable contribution for practical application was also the introduction of the term lower loading fine as well as the correlations from which the lower loading line can be analytically derived.

The capacity diagrams, showing the pressure drop parameter [1,8,9, 21, 29, 55], are very useful for estimating the pressure drop Ap/H. Mersmann [21, 55] and Reichelt [1] give an accuracy of 25% and 20%, respectively. According to Molzahn and Wolf [25] as well as Bla6 and Kurtz [42,43], the accuracy of the graphic correlations is 50%. 

The following Figs. 7-10, 7-11, 7-12 and 7-13 show the capacity diagrams for a number of different packed columns, using various systems, acc. to Table 7-1 [11,12,13,14]. They form the basis for the development of the author s own model for determining the flooding capacities in non-pulsed extraction columns [15].
