NOVELTY - Distillative separation of at least one feed mixture in a column with one, two or three partition or partitions continuously arranged in the longitudinal direction of the column from one end to the other end of the column, which separates the column interior into two, three or four column sections, which are completely separated from each other, with a directional exhaust flow guidance from a first column section into a second and optionally a third and optionally a fourth column section and with a directional fluid flow in countercurrent manner to exhaust flow guidance, is claimed.    USE - The method is useful for distillative separation of: 3C-section in the first fraction containing propane (at least 70 wt.%, preferably at least 90 wt.%) and a second fraction containing propene (at least 99 wt.%, preferably at least 99.9 wt.%); and 4C-hydrocarbon section in the raffinate l-stream containing butane, butene and 1,3-butadiene (maximum of 2000 ppm), and a raw 1,3-butadiene stream containing 1,3-butadiene (at least 98 wt.%) (all claimed).    ADVANTAGE - The method: is carried out without the assistance of a solvent; utilizes a single column with larger diameter and high mechanical stability, which reduces the continuous exposure to wind and earthquake sensitivity; does not require expensive reinforcements, thus it is cost effective; and requires less space.    DETAILED DESCRIPTION - Distillative separation of at least one feed mixture in a column with one, two or three partition or partitions continuously arranged in the longitudinal direction of the column from one end to the other end of the column, which separates the column interior into two, three or four column sections, which are completely separated from each other, with a directional exhaust flow guidance from a first column section into a second and optionally a third and optionally a fourth column section and with a directional fluid flow in countercurrent manner to exhaust flow guidance, where at least one feed mixture is separated into two fractions in the column and the column exhibits a single bottom evaporator and single condenser at the column top, is claimed.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of a partition column for carrying out the method.
