Binary Distillation Column with 30 trays (cyclohexane n-heptane)
Distillation column models are generally good test models for nonlinear model reduction and identification. The concentrations at each stage or tray are highly correlated.The dynamics of the distillation process can be described by a relatively few number of underlying dynamic states. A: couple papers have been published with this model as an example application. One in particular is
Hahn, J. and T.F. Edgar, An improved method for nonlinear model reduction using balancing of empirical gramians, Computers and Chemical Engineering, 26, pp. 1379-1397, (2002)
This plot shows the system response after a step change in the reflux ratio from 3.0 to 1.5.
Each trajectory represents the mole fraction of cyclohexane at each tray. The top reflux
material becomes less pure (more n-heptane) due to the increased draw from the top
