Question 3.
450 kmol per hour of a mixture of n-butanol and iso-butanol containing 30
mole% n-butanol is separated by distillation into two fractions. The flow
rate of n-butanol in the overhead stream is 120 kmol/h and that of iso-
butanol in the bottom stream is 300 kmol/h. The operation is at steady
state. Calculate the unknown component flow rates in the output streams.
