Abstract: Sudstituted the abstract with a new abstract as follows: The invention relates to a continuous process for separation a mixture of hydrocarbons which has beenobtained by extractive distillation of C 4 fraction useing a selective solvent and the hydrocarbons from the fraction C 4 which are more readily soluble in the selective solvent than are the butanes and the butenes. The mixture is fed into a first distillation column in which it is separated into a steam which is taken off at the top and comprises 1,3-butadiene, propyne, possibly further low boilers and possibly water and a bottom stream comprising 1,3-butadiene, 1,2-butadiene, acetylenes and possibly further high boilers, with the proportion of 1,3-butadiene in the bottom stream from the distillatin column being regulated in such a way that it is at least sufficiently high to dilute the acetylenes to outside the range in which there is a risk of spontaneous decomposition. The stream taken off from the top of the first distillation column is fed to a second distillation column and is separated into a steam which is taken off at the top and comprises propyne, possibly further low boilers and possibly water and a bottom stream comprising pure 1,3-butadiene in the second distillation column.

Abstract: A process for obtaining pure 1,3-butadiene from crude 1,3-butadiene by distillation is carried out in a dividing wall column in which a dividing wall is located in the longitudinal direction of the column to form an upper common column region, a lower common column region, a feed section and an offtake section.

Abstract: A process for recovering crude 1,3-butadiene from a C 4 fraction by extractive distillation using a selective solvent in a dividing wall column (TK) in which a dividing wall (T) is arranged in the longitudinal direction of the column to form a first subregion (A), a second subregion (B) and a lower common column region (C) and which is preceded by an extractive scrubbing column (K) is proposed.

Abstract: In a process for the work-up of a C4 fraction, comprising the process steps Extractive distillation (I), Selective hydrogenation over a heterogeneous catalyst (II), a crude 1,3-butadiene stream being obtained following process steps (I) and (II) and Distillation of the crude 1,3-butadiene stream for isolating pure 1,3-butadiene (III), the process steps I and II are carried out in a single column or in thermally coupled columns and the process step III is carried out in a second column.

Abstract: In a continuous process for fractionating a C4 fraction (C4) by extractive distillation using a selective solvent (LM) in an extractive distillation column (EDK), it is proposed that a dividing wall (TW) is installed in the longitudinal direction in the extractive distillation column (EDK) to form a first region (A), a second region (B) and a lower combined column region (C) and a top stream (C4H10) comprising the butanes is taken off from the first region (A), a top stream (C4H8) comprising the butenes is taken off from the second region (B) and a stream (C4H6) comprising the hydrocarbons from the C4 fraction which are more soluble in the selective solvent (LM) than are the butanes and the butenes is taken off from the lower combined column region (C).
