Procedure for the construction of attainable region

Advantages (i) this method allows one to point out promising flowsheets (ii) the reaction-separation vector has the same geometric properties as simple reactor models, allowing the application of the theory derived for PFRs and CSTRs and (in) this method can be easily extended to multiphase systems. 

A sound understanding on fixed points (c/. explanatory note 3.1) and the prediction of their behavior as a function of design parameters have been lately used as a design tool for RD columns. 

Similarly to the molar fractions, molar flow rates are transformed as suggested by Giittinger (1998),
