A feed to a continuous distillation column is a mixture of 54 mol% benzene (C6H6, MW = 78) and 46 mol% toluene (C7H8, MW =92). The column is atmospheric. If the feed enters as 40 mol% liquid and 60 mol% vapor, determine minimum reflux ratio to achieve a 90% purity of benzene in the distillate and 90% purity of toluene in bottoms. Must use shortcut method. 54 Pen Nt0 0.692 KF O.S80S een wt t 48 46 O,092 t 6.S 92 48
