Transcribed Image Text:4.10. Continuous, single-stage distillation.
Saturated-liquid feed of F = 40 mol/h, containing 50 mol% A
and B, is supplied to the apparatus in Figure 4.23. The condensate is
split so that reflux/distillate = 1.
(a) If heat is supplied such that W = 30 mol/h and α = 2, as defined
below, what will be the composition of the overhead and the bot-
toms product?
