Ethyl alcohol can be dried by extractive rectification with monoethylene glycol more efficiently than with the triethylene glycol used industrially. The extractive rectification of ethyl alcohol does not require stabilization of the column with the distillate of dried alcohol, which can only worsen the process characteristics. The required reflux ratio is generated as a result of absorption of ethyl alcohol vapor by the extractant. To reduce the water content of ethyl alcohol from 6 to 0.5 wt. % with a yield not less than 70% the rectifying section of the column must have not less than six theoretical plates.
