A procedure for computing the minimum reflux rate for multicomponent distillation systems. The equations developed apply to both distributed and non-distributed systems. The suggested method of solution is by iteration, beginning with the assumption the system will be distributed. Complete heat and material balances are carried out in the course of each plate calculation. The calculated minimum reflux rates are compared with those of other techniques.
On decrit une methode de calcul du taux minimum de reflux pour la distillation fractionnee des melanges complexes. Les equations presentees sont d'ordre general et s'appliquent a tous les systemes, que leurs composants soient ou non partages entre le distillat et le residu, quoique la methode iterative de solution suggeree presuppose un tel partage. Les calculs relatifs a chacun des plateaux comportent des bilans complets de chaleur et de matiere. On compare les taux minima de reflux obtenus par calcul avec ceux que l'on obtient au moyen d'autres techniques.
