$A distillation column is separating a feed that is 40 mole\%$ $methanol and 60 mole\% water. The twophase feed is 60% liquid. Distillate$

A distillation column is separating a feed that is 40 mole\% methanol and 60 mole\% water. The twophase feed is 60% liquid. Distillate product should be 92 mole\% methanol, and bottoms 4 mole\% methanol. A total reboiler and a total condenser are used. Reflux is a saturated liquid. Operation is at 101.3 kPa. Assume CMO, and use L/D=0.9. Under these conditions HG=1.3 feet and HL=0.8 feet in both the enriching and stripping sections. Determine the required heights of both the enriching and stripping sections. The equilibrium curve is given on the next slide. Methanol Mole Percent (Vapor)
