Transcribed Image Text:A feed of component A and B containing 55 mole % of
A is fed to a distillation tower at a rate of 40 kmol/h.
and operating pressure of 1 atm. The feed is at bubble
point. The top product A fraction is 0.975. Also not
more than 2% of A in the feed should be allowed to
leave at bottom.
