Stripping Tower. A liquid mixture containing 10 mo! % n-heptane and 90 mol %
n-octane is fed at its boiling point to the top of a stripping tower at 101.32 kPa
abs. The bottoms are to contain 98 mol % n-octane. For every 3 mol of feed, 2
mol of vapor is withdrawn as product. Calculate the composition of the vapor
and the number of theoretical plates required. The equilibrium data below are
given as mole fraction n-heptane.
