A mixture consisting of 15 mole % Phenol in water is to batch distilled at 260 torr, what fraction of the original batch is remains in the still when the total distillate contain 98mole % w water? What is the residues concentration? Change the feed compositions (5 values) and the distillate (5 values), Draw the plot (xf vs xw) and (xf vs yD), and write your illustrations.
