6. Choosing and comparing trainers
6.1 Process feasibility and other selection criteria
To separate a non-ideal A-B binary mixture, a light carrier can be added (its boiling temperature is lower than that of A and B, TB > TA > TE); intermediate (TB > TE > TA) or heavy (TE > TB > TA).
Once a process has been chosen, the main criterion for selecting an entrainer for distillation is the feasibility of total reflux separation according to the principles outlined in this dossier. This is supplemented by economic and thermodynamic criteria such as selectivity.
For azeotropic distillation, feasibility at full reflux implies feasibility at finite reflux in the continuous...
