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
a. Determine the amount of distillate
b. Determine the concentration of naphthalene in residue and distillate
In this problem, the amount of distillate and composition of naphthaline in the top layer and residue has been determined. The solution is detailed and well presented.
