Corn is inexpensive (5 to 10c/lb), operates at relatively mild conditions (close to atmospheric pressure, and 80 to 110 deg C), and provides an energy efficient means to remove water from ethanol. The adsorption of water from water/ethanol mixtures over ground corn or corn grits indicates that a combined wavefront is formed.
