A mixture of water and ethyl alcohol containing 0.16 mole fraction alcohol is continuously distilled in a plate fractionating column to give a product containing 0.61 mole fraction alcohol and a waste of 0.02 mole fraction alcohol. It is proposed to withdraw 10 percent of the alcohol in the entering stream as a side stream containing 0.50 mole fraction of alcohol. Suppose the feed is liquid at its boiling point with a flowrate of 100 kgmole/h and a reflux ratio of 2 is used. What is the molar flow rate in kgmole/h of the distillate?
