摘要： A process is proposed for purifying a recycle stream (1) from an installation (A) processing 1,3-butadiene, wherein - the recycle stream (1) is divided into two substreams, namely a first substream (3) which is purified in a stripping column (K1) for prepurification of the pure 1,3-butadiene feed stream (2), obtaining a first purified recycle stream (4) which co-comprises the prepurified pure 1,3-butadiene feed stream (2), and also - a second substream (5) which is purified in an extracted distillation installation by extractive distillation using a selective solvent (6), wherein the extractive distillation installation comprises - a main scrubber (K2) which is constructed as an enrichment column, and also - a gas-stripper column (K3), with the proviso that the recycle stream (1) is divided in such a manner that a quantitative stream as large as possible is apportioned to the first substream (3), maintaining the specification requirements for the sum of all streams that are fed into the installation (A) processing 1,3-butadiene, of a fraction of 1,3-butadiene of greater than or equal to 90% by weight, based on the total weight of the C
4 hydrocarbons of the sum of all streams fed into the installation (A) processing 1,3-butadiene.

摘要： The invention relates to a method for providing a vaporous purified crude C
4 fraction as a feed stream for an extractive distillation process using a selective solvent, having the method steps of 1) separating the C
3 -hydrocarbons, 2) separating the C
4 -oligomers and -polymers as well as the C
5+ -hydrocarbons up to the respective residual content specified above for the vaporous purified crude C
4 fraction, and 3) evaporating the liquid crude C
4 fraction. The method is characterized in that all the method steps 1), 2), and 3) are carried out in a single distillation column which is fed the liquid crude C
4 fraction in the upper third of the column thereby forming a rectifying section and a stripping section and from which a head stream containing the C
3 -hydrocarbons and a bottom stream containing the C
4 -oligomers and -polymers as well as the C
5+ -hydrocarbons are drawn, and the vaporous purified crude C
4 fraction is drawn from the stripping section as a side stream.

摘要： The invention relates to a column (K) with separative installations (E) for separating a mixture of hydrocarbons and/or hydrocarbon derivatives (1) by means of an extractive distillation using a selective solvent (2) by supplying the selective solvent (2) in the upper column region and supplying the hydrocarbons and/or hydrocarbon derivative (1) mixture to be separated below the supply of the selective solvent (2). In the column (K), the selective solvent (2) is loaded with the mixture (1) components for which the solvent has a higher affinity, and the solvent is discharged from the lower column region as a loaded selective solvent (3), whereas the mixture components for which the selective solvent (2) has a lower affinity remain in the vapor phase and are drawn as a top stream (4), which is completely or partly condensed while obtaining a condensate (5) that is drawn partly as a product stream (6) and otherwise returned to the column (K) as a return stream (7). The invention is characterized in that - a first substantially horizontal inlet pipe (R1) for supplying the selective solvent is provided in the column region above the separative installations (E), - the first substantially horizontal inlet pipe (R1) has a cross-sectional constriction up to a narrowest point (V) and expands again after the cross-sectional constriction, and - a second inlet pipe (R2) is provided which opens into the first substantially horizontal inlet pipe (R1) in the region of the narrowest point of the cross-sectional constriction (V) for supplying the return stream (7).
