A distillation station for separating components of a liquid mixture, comprising a vertical distillation column split into individual separation stages by fittings and which is further split by the liquid mixture feed into a stripping chamber and an enriching chamber, wherein in the stripping chamber the lower boiling fraction of vapour from the fluid mixture rising from a column sump comprising an evaporator is stripped, and in the enriching chamber the vapour is enriched with the lower-boiling fraction, which is withdrawn from a return fluid produced due to the vapour drawn from the column head being precipitated at least partially in a condenser and returned to the rectifier column, and the return liquid and the liquid mixture preferably fed between two separating stages being routed to the fittings vertically connected in sequence. In the process, each of the fittings comprise at least one liquid channel, which is separated at least partially from the vapour chamber of the distillation column by a two-sided vapour-permeable, liquid-tight membrane wall. |
