Question

(d) None of the mentioned

I have been asked this question by my college director while I was bunking the class.

My query is from Design of Fractionator with Mc-cabe Thiele Method in portion Distillation of Mass Transfer

Answer 1

The correct choice is (a) Same concentration  of distillate and reflux

To explain: Since the latent heats are alone removed by the condenser so the concentration of liquid entering the condenser and the concentration leaving the condenser are same.
