Abstract
A device for concentrating ethanol from an ethanol water solution yielded from lignocellulose is equipped with a water separation membrane, an ethanol water solution storing unit and a depressurizing container provided so as to sandwich the water separation membrane, a dry gas cylinder for supplying dry gas to an ethanol vapor residing unit above the ethanol water solution storing unit, a pump for sucking in the interior of the ethanol vapor residing unit, and a cold trap for collecting the concentrated ethanol by condensing the ethanol vapor sucked in by the pump.
