| titleOfInvention | Method and device for extractive distillation |
| abstract | The invention relates to a method for separating an initial mixture (A) consisting of at least two components by means of extractive distillation using a selective solvent (s) in a separation column (TKW) provided with a separation baffle. Said invention is characterised in that the inventive method is carried out in the separation column (TKW) provided with the separation baffle (TW) which is disposed in the direction of the length of the column, extends to the top end thereof and divides the inside of the column into a first partial area (1), a second partial area (2) and a common lower area (3), the initial mixture (A) is introduced into said first partial area (1), a first head flow (B) is extracted therefrom, the second head flow (c) is extracted from the second partial area (2), said flows exhibiting the predefined characteristics, the selective solvent (S) is distributed in the top section of the first partial area (1) and/or in the top section of the second partial (2), and than the quantity of the selective solvent (S1) distributed in the first partial area (1) and the quantity of the selective solvent (S2) distributed in the second partial area (2) are controlled in such a way that said predefined characteristics for each head (B, C) flow are respected, respectively. |
