An ethanol-water mixture is to be treated in a distillation column to produce a
distillate product at a rate of 200 kmol/hr containing a mol fraction of 0.96 for ethanol.
The bottoms product should not contain more than 0.14 mol fraction ethanol. Draw a
schematic diagram representing the process and calculate the flow rates of the feed
stream and bottoms product stream if 54 % of the ethanol in the feed stream is
recovered to the distillate stream. A side stream is extracted at a rate of 30% of that
of the feed rate and has a mol fraction of 0.7 of ethanol.
