	The paper presents a project of a rectification column working periodically for the production of ethyl alcohol. The project contains an assumption of a steady concentration of the distillate. Thee range of change in the reflux from 1.7 to 13 required to obtain that concentration was calculated. With 50 litres of feed containing 9 mol % ethanol, about 10 litres of distillate was obtained, which has 70 mol % ethanol. Ceramic Raschig rings with a diameter of 15 mm, which, in a column, occupy a height of 0.5 m, were used. The height of the entire column was 0.67 m.
