Problem:
A liquid feed consisting of 1200 gmoles of mixture containing 30%
naphthalene and 70% dipropylene glycol is differentially distilled at
100 mm Hg pressure and final distillate contains 55% of the feed
solution. The VLE data are
x 8.4 11.6 28.0 50.6 68.7 80.6 88
y 22.3 41.1 62.9 74.8 80.2 84.4 88
determine the amount of distillate
determine the concentration of naphthalene in residue and distillate
