Mass transfer models for

Bolles and Fair [129] present an analysis of considerable data in developing a mass-transfer model for packed tower design however, there is too much detail to present here.

The researchers interpreted the mass transfer coefficient with the mass transfer model for absorption, and the resulting empirical relationships represent the Sherwood number Sh as a function of Reynolds number Re. For details, the reader may refer to Ref. [25]. It is clear that the items included in the relationships they obtained are related closely to the reactor structure. 

Individual component efficiencies can vary as much as they do in this example only when the diffusion coefficients of the three binary pairs that exist in this system differ significantly For ideal or nearly ideal systems, all models lead to essentially the same results. This example demonstrates the importance of mass-transfer models for nonideal systems, especially when trace components are a concern. For further discussion of this example, see Doherty and Malone (op. cit.) and Baur et al. [AIChE J. 51,854 (2005)]. It is worth noting that there exists extensive experimental evidence for mass-transfer effects for this system, and it is known that nonequilibrium models accurately describe the behavior of this system, whereas equilibrium models (and equal-efficiency models) sometime...
