Abstract: Distillation column has a dividing wall which divides it into inflow and extraction sections, and upper and lower column zones. The mixture for distillation comprises a vapor feed which enters between the upper and lower inflow sections, between which the side extraction point removes vapor. The inflow and the extraction zones are offset relative too the dividing wall. The vapor feed rate is equal in all zones of the column. The distillation column has a dividing wall (TW) which divides it into an inflow section (2,4), an extraction section (3,5), and common upper (1) and lower (6) column zones. The mixture for distillation is at least partially a vapor feed (F) which enters between the upper and lower inflow sections, and the side extraction point (B) removes vapor between the upper and lower extraction zones. The cross sectional surfaces of the inflow and the extraction zones are set by an offset in the dividing wall. The F-factor is equal in all the zones of the column, defined as the product of the gas flow speed in m/seconds multiplied with the square root of the gas density in kg/m3.

Abstract: A column is described for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst having an ordered packing or random packings which form intermediate spaces in the column interior, the quotient of the hydraulic diameter for the gas flow through the ordered packing or the random packings and the equivalent diameter of the catalyst particles being in the range from 2 to 20, preferably in the range from 5 to 10, in such a manner that the catalyst particles are introduced into the intermediate spaces, distributed and discharged loose under the action of gravity.
