A continuous rectification column is used to separate a binary mixture of A and B. Distillate is produced at 100 kmol/hr containing 98 mole % A. The mole fractions of A in the liquid and in the vapor, z and y respectively, from two adjacent ideal plates in the enriching section are as follows: 0.65 0.82 0.56 0.76 If the latent heat of vaporization is the same for all mixtures and if the feed is a saturated liquid, calculate: (a) the reflux ratio (b) vapor rate in the stripping section in kmol/hr.

A continuous rectification column is used to separate a binary mixture of A and B. Distillate is produced at 100 kmol/hr containing 98 mole % A. The mole fractions of A in the liquid and in the vapor, I and y respectively, from two adjacent ideal plates in the enriching section are as follows: 0.65 0.82 0.56 0.76 If the latent heat of vaporization is the same for all mixtures and if the feed is a saturated liquid, calculate: (a) the reflux ratio L(b) vapor rate in the stripping section in kmol/hr.
