    摘要: A dividing wall column comprises the following segments:a) an upper column region (1),b) an enrichment section (2) of the feed section,c) a stripping section (4) of the feed section,d) an upper part (3) of the offtake section,e) a lower part (5) of the offtake section,f) an intermediate region (9) of the feed section,g) an intermediate region (10) of the offtake section andh) a lower column region (6).For the purposes of the present invention, it is essential that the dividing wall (7) is located vertically between the segments b) (2) and d) (3) and between the segments c) (4) and e) (5), the segments b) (2), d) (3), c) (4) and e) (5) have separation-active internals and the cross-sectional area Ab of the segment b) (2) is at least 10% smaller than the cross-sectional area Ad of segment d) (3), and the cross-sectional area Ac of the segment c) (4) is at least 10% greater than the cross-sectional area Ae of segment e) (5).
