Résumé :	Column profile maps (CPMs) have recently been shown to be a useful tool in the design of distillation operations, especially complex configurations. CPMs are essentially a family of composition trajectories for a column section in a distillation column. They have been shown to be topological transforms of residue curve maps, and are dependent on two main parameters: RΔ (generalized reflux) and XΔ (a pseudocomposition vector), which effectively fixes the net flow in a column section. This paper focuses on the interaction between these parameters for the special case of sharp splits. With the CPM technique it has been shown that sharp splits behave in a unique manner, due to a phenomenon termed as "node bumping". In particular, it has been shown that it is possible to locate specific ranges of RΔ where one may drastically influence the movement of profiles in somewhat counterintuitive directions. Although this effect may not be useful in product producing column sections, it is shown how these unique phenomena can affect a separation in a desirable manner, especially when designing unconventional column configurations.
