Abstract

L'invention concerne la séparation du butadiène des mélanges en contenant Elle se rapporte à un procédé dans lequel la chaleur nécessaire au fonctionnement de la colonne de distillation finale du butadiène est transmise par condensation du courant de solvants polaires sous forme de vapeurs chaudes qui a été utilisé pour la distillation avec extraction au cours d'une étape antérieure du procédé. Application à la réduction de la consommation d'énergie des installations de séparation de butadiène.
