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: 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: Processing of a 4C cut from the fractionation of crude oil comprises: (A) extractive distillation; (B) selective hydrogenation by heterogeneous catalysis; and (C) distillation to obtain 1,3-butadiene whereby steps (A) and (B) are carried out in individual columns or thermally coupled columns and step (C) is carried out in a second column. An Independent claim is also included for an apparatus to carry out the process comprising a separating wall column (TK) in which the separating wall lies in the longitudinal axis of the column to form a common upper column section (1), a common lower column section (6), inlet sections (2a, 2b, 4) and outlets sections (3a, 3b, 5a, 5b) whereby hydrogen (H) is added to the lower section (6); unreacted hydrogen is separated from the vapor stream of condensable light boiling components from (TK) in a condenser (K) with recycle via a compressor (V) to the lower section (6); with passage of the 1,3-butadiene containing stream (B) from the outlet sections (3a, 3b, 5a, 5b) of (TK) at a position beneath the inlet (F) for sections (2a, 2b, 4); and passage of the stream (B) for purification by distillation (step (C)).

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.
