This is a method to remove ethanol from a simultaneous saccharification and fermentation process (SSF) contained in a vessel. The preferred method employs carbon dioxide, supplied to the vessel, to humidify ethanol and volatile compounds formed by fermentation. Ethanol from the process is transmitted to carbon dioxide to humidify the carbon dioxide. The carbon dioxide containing humidified ethanol and carbon dioxide created by fermentation within the SSF process is removed from the vessel and substantially separated from the ethanol. Carbon dioxide, substantially separated from the ethanol, is recycled to the vessel to humidify additional ethanol from the fermentation process within the vessel.
