Abstract: The column is provided for carrying out an isotope exchange (EM) between a liquid substance (L) and a gaseous substance (G) using a catalytic reaction (EK). In this reaction the isotope exchange between molecules of the vaporized liquid substance (V) and molecules of the gaseous substance (G) takes place through a heterogeneous catalysis. The column comprises a plurality of modules (M) which are arranged vertically one above the other and which are in each case subdivided into two regions K and A which are serially connected by a connection region (C). The catalytic reaction can be carried out in the region K on a first packing (2). A substance exchange (E1, E2) between a liquid and a gaseous phase which contains vapor can be carried out in the region A by means of a second packing (3) for compensating substance concentrations. During the operation of the column a transport of the gaseous substance (G, V) which contains vapor is driven through the modules as a result of pressure gradients.

Abstract: A method for separating a first liquid from a second liquid, with the one liquid not being soluble in the other, the first liquid being contained as droplets in the second one, and with the two liquids having different densities. In a first step the liquid mixture is conducted during a first time interval as a turbulent flow through installations, in particular through a filler body in a packing column or through a static mixer, for coalescing the droplets. In a second step the flow rate of the mixture is reduced during a second time interval to continue the coalescence, and, in a third step, the speed of the mixture flow is further reduced and directed opposite to or with the force of gravity so that larger descending or rising droplets can be collected and separated out. The smaller droplets are carried along further by the second liquid.
