An ethanol plant distills alcohol from corn. The distiller processes 2.0 t/h of feed containing 15 percent alcohol and 82 percent water; the rest is inert material. The bottoms (waste) produced is 85 percent of the feed and contains 94 percent water, 3.5 percent alcohol, and 2.5 percent inert material. The vapor (product) from the top of the distiller is passed through a condenser and cooled to produce the final product. Determine the rate of production of the final product and its composition.
