Liquid from a brewery fermenter can be considered to contain 10% ethanol and 90% water. 50000 kg h-1 of this fermentation product are pumped to a distillation column on the factory site. Under current operating conditions a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate one-tenth that of the feed.
