    • 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).
    • 分隔壁柱包括以下部分:a)上部柱区域(1),b)进料部分的富集部分(2),c)进料部分的汽提部分(4),d)上部部分 (3),e)出料部分的下部(5),f)进料部分的中间区域(9),g)出料部分的中间区域(10)和h)a 下列区域(6)。 为了本发明的目的,重要的是分隔壁(7)垂直位于段b)(2)和d)(3)之间以及段c)(4)和e)(5)之间。 ,分段b)(2),d)(3),c)(4)和e)(5)具有分离活性的内部,并且段b)(2)的横截面积Ab至少为10 (3)段的横截面面积Ad的百分比小于段c)(4)的横截面积Ac比段e)的横截面积Ae至少大10%( 5)。
