Patent abstract
The invention is a process for the purification of ethanol. In one embodiment the process includes boiling a degassed beer feed (106) in a pre-boiler (110) to provide a vapor by-pass fraction (112) that by-passes the conventional beer column and is fed into the rectifier column (124). The process allows free capacity in the rectifier column of new or established plants to be filled by ethanol-water vapor and/or condensate streams that do not originate from the beer column.
