Rectifying and Stripping Profiles for the Reactive Cascade

Damköhler number

0.5

Stripping and rectifying profiles for the reactive cascade are similar to stripping and rectifying sections of a continuous reactive distillation column, but without vapor or liquid recycles, respectively. This Demonstration computes the stripping and rectifying profiles for the reactive cascade for various values of the Damköhler number

a

. The stripping profile is represented by the orange dots while the rectifying profile is given by the blue dots. The reaction equilibrium curve is cyan. At large Damköhler numbers (

>10

), the stripping profile (the orange dots) merges with the reaction equilibrium curve, indicating that the system has reached chemical equilibrium. The fixed point (the point to which the blue dots converge) for the rectifying cascade is pure
