| titleOfInvention | Separation of C4 fraction by extractive distillation using selective solvent |
| abstract | The present invention relates to a process for separating C 4 fraction (2) by extractive distillation using a selective solvent (1), wherein an upper stream (3) containing butane and butane derived from C 4 fraction, The liquid phase selective solvent and the C 4 fraction are distilled in the distillation units (KI, KII) together with the separation of the bottoms stream (6) containing the remaining components of the C 4 fraction and the optional solvent, of deaerated and the other components of the C 4 fraction, and the energy is discharged from the distillation unit (KI, KII) between the discharge point of the discharge point and the bottom stream (6) of the upstream (3). |
