Wankat D3 Separations problem

D3.* We have a feed mixture of 22mol% methanol, 47mol% ethanol, 18mol%n-propanol, and 13mol%n-butanol. Feed is a saturated liquid, and F=10,000kmol/ day. We desire a 99.8% recovery of methanol in the distillate and a methanol mole fraction in the distillate of 0.99 . a. Find D and B. b. Find compositions of distillate and bottoms.
