APPLICATION OF COLUMN PROFILE MAPS TO ALTERNATIVE SEPARATION PROCESSES MEMBRANE PERMEATION 

A logical question that arises at this point is whether CPM theory can be applied to other separation systems. In an effort to illustrate this, we will consider membrane permeation because of its striking difference from distillation. By the nature of its operation, membrane separation is fundamentally different while in distillation, the separation is achieved by differences in boiling points, the driving force in membrane permeation is a difference between chemical potentials in the two phases. One of the most important consequences of this is that the constant molar overflow assumption, in general, cannot be employed in membrane permeating systems.
