A continuous rectification column o perating at 1 atm is to be designed to separate a binary mixture of A and B (AA is more volatile than B)) . A distillate composition (xx D ) of 9 4 mol%% A is achieved . The liquid over flowing from two adjacent plates contain 58 mol%% and 75 mol%% A , respect ively.. The equilibrium curve for the binary system at 1 atm is given in Figure A3.. Solve graphically using the equilibrium curve and determine the reflux ratio
