Abstract
Partial differential equations and boundary conditions are derived for the large-and-small-signal behaviour of compositions in an ideal, symmetrical spatially-continuous (packed) distillation column separating a binary mixture. A precise paramemtric transfer-function matrix (T.F.M.) for the system is derived completely analytically so allowing the calculation of parameters of the T.F.M. directly from those of the plant. It is shown that the correct choice of input and output vectors yields a completely diagonal system (i.e. the system is Dyadic in structure).
The investigation reveals important differences between the behaviour of packed and tray-type distillation columns examined in companion papers. In particular, important non-minimum phase effects are shown to occur in some packed columns that are not found in tray types.
