Concentration of ethanol in water solution by distillation from a fermentation is produced a mixture of ethanol in water. the concentration of ethanol is 4 mol %. the ethanol is to be concentrated by distillation, and the distillate must contain 38 volume % ethanol. at 20 °c this is equivalent to 31.5 mass % ethanol. a) convert 31.5 mass % ethanol to mol %. b) a distillation column is at hand. it can provide a distillate of 30 mol % ethanol and a bottom product of 1.0 mol % c) is the process feasible? d) draw a block diagram for the distillation process. e) calculate the yield of ethanol after the distillation, i.e. ethanol in the distillate compared to ethanol in the feed.
