ABSTRACT:
The invention relates to a sieve-plate column for liquid-liquid counterflow extraction of two phases which are of different weights and which are not soluble one in the other. A mixing arrangement is disposed between two sieve plates. In order to further increase cross-mixing of the phases and thus the material exchange thereof with a good rate of through-put, a static mixing element is arranged between each two sieve plates. Static mixing elements generally have, over their entire cross-section, a plurality of open channels which are arranged adjacent to each other and which extend inclinedly with respect to the direction of flow, the upper opening and the lower opening of each channel thereby being displaced radially relative to each other.
