It was confirmed that the analogous relations between unsteady one-dimensional chromatographic process and steady two-dimensional CAC process proposed by Wankat still exist regardless of the bioreaction, and the analogous results were shown. A mathematical relation between the feed and the eluant flowrates was established for keeping the CAC in good operation. The optimization of the hybrid process were also discussed.
