Find the rate of distillate, if the composition of the more volatile component in the feed is 50% and the residue is 10% and the equilibrium relation is given by y*= 1.975x. Also the rate of residue is 60 mol/hr.

Find the rate of distillate, if the composition of the more volatile component in the feed is 50% and the residue is 10% and the equilibrium relation is given by y*= 1.975x. Also the rate of residue is 60 mol/hr. Correct Answer 253 mol/hr

Using the Rayleigh equation, we can estimate ln (F/W)= 1.657 F= 313 mol/hr then D= 253 mol/hr.
