The feed to a conventional distillation column and the relative volatilities are shown in the following table. The recovery of component 2 in the distillate is 99% and 98% of component 3 is to leave in the bottoms. Estimate the minimum reflux ratio if the feed is liquid at the boiling point. About how many plates would be required at a reflux ratio 1.3 times the minimum?  Component Mole fraction Relative volatility 1 0.05 2.10 2 0.42 1.70 3 0.46 1.00 4 0.07 0.65
