The Stripping Column Section

The preceding section deals with the experimental validation of column profiles in rectifying CSs. However, it is just as important to be able to model stripping sections, as these operating conditions may shift topology inside the MBT in ways that

The time-dependent differential equation describing the composition transformation in this still can easily be shown to be 

In our stripping CS, the ratio of EfV can easily be converted into the generalized definition of = L/(V — L), such that Equation 4.11 may be rewritten, in the vectorized form as
