Abstract: The present invention pertains to the alcohol processing industry and relates to a method that includes feeding a mixture into a distillation column which is fitted with contact devices for discharging the vapors through the top of said column. This method further includes boiling a bottom product and supplying the vapor thus formed back into the column. A part of the vapor to be processed using one of said contact devices is then fed back into the vapor flow or liquid flow towards one at least of said devices located upstream relative to the flow direction. In another or the same embodiment, a part of the vapor is fed back into the liquid flow under the level thereof and towards the same contact device in a place that is located upstream from its discharge relative to the flow direction of said vapor. The vapor feedback is preformed without complete condensation thereof.
