- 1 - Abstract of the disclosure: A process for the continuous rectification of a liquid mixture containing alcohols, in particular a fer- mented mash which has been substantially or completely freed from suspended substances, in an apparatus which is composed of several distillation columns linked with one another on the vapor side and which, in addition to a sec- tion used for the concentration of alcohol, can also con- tain a section used for the production of absolute alcohol, with the repeated utilization of the heat energy supplied on the multi-effect principle, which comprises a) distributing the liquid mixture in parallel to the distillation columns in the section of apparatus used for the concentration of alcohol, and feeding direct steam, having a temperature of 130 to 160°C, to the sump of the column operated at the highest pressure; b) recovering heat energy in the form of direct steam from the top vapor of this column by means of a heat ex- changer and feeding this steam, together with flash steam, formed in the sump of the same column, in a flash vessel, to the stripping section of the second column following; c) recovering direct steam in the same manner also from the top vapor of the second column and feeding this steam, together with the flash steam obtained from the sump of this column, to the third column, and, if appropriate also operating further downstream columns in this manner, the - 2 - contentrated alcohol condensing in the heat exchangers being withdrawn, minus the portion refluxed, and, if appro- priate being fed to a section for the production of abso- lute alcohol, in which d) the residual water still remaining is substantially removed from the concentrated alcohol by azeotropic dis- tillation in one or more columns connected with one an- other in tandem on the vapor side.
