An ideal ternary mixture A, B, and C for which average a -values and distillate and bottoms compositions are given, is to be fractionated. Calculate the minimum reflux by the Underwood equations for both Class 1 and Class 2 cases if the feed is a saturated liquid. Note that the data given indicate that only the HK and LK distribute. However, at minimum reflux, this may not be the so. Do your results indicate that this is just a Class 1 seperation?
