Abstract: A C4-hydrocarbon mixture essentially containing 1,3-butadiene, butenes, butanes and other C4-hydrocarbons is separated into at least 4 fractions,a) the fraction (a) essentially comprising 1,3-butadiene,b) the fraction (b) essentially comprising butenes,c) the fraction (c) essentially comprising butanes andd) one or more fractions (d) essentially comprising 1,3-butadiene and the other C4-hydrocarbons,by extractive distillation by means of N-methyl-2-pyrrolidinone or an aqueous solution of N-methyl-2-pyrrolidinone (NMP).

Abstract: The invention relates to a method for separating a C4 hydrocarbon mixture containing essentially 1,3 butadiene, butenes, butanes and other C4 hydrocarbons into at least 4 fractions as follows: a) fraction (a) consisting essentially of 1,3 butadiene; b) fraction (b) consisting essentially of butenes; c) fraction (c) consisting essentially of butanes; and d) one or more fractions (d) consisting essentially of 1,3 butadiene and the other C4 hydrocarbons. According to said method, the C4 hydrocarbon mixture is separated by extractive distillation using N-methyl-2-pyrrolidinone or an aqueous solution of N-methyl-2-pyrrolidinone (NMP).

Abstract: The invention relates to a continuous method for separating a C4 cut (C4) by means of extractive distillation using a selective solvent (LM) in an extractive distillation column (EDK). A separating wall (TW), forming a first partial region (A), a second partial region (B) and a lower common column region (C), is arranged in the longitudinal direction of the extractive distillation column (EDK). According to said method, a head flow (C4H10) comprising butane is separated from the first partial region (A), a head flow (C4H8) comprising butene is separated from the second partial region (B), and a flow (C4H6) comprising the hydrocarbons from the C4 cut is separated from the lower common column region (C), said hydrocarbons dissolving more easily in the selective solvent (LM) than the butane and the butene.

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).

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.
