separation process

= D14.* We are operating a staged distillation column at total reflux to determine the Murphree efficiency. Pressure is 101.3 kPa. We are separating methanol and water. The column has a 2-inch head of liquid on each well-mixed stage. The molar vapor flux is 30 lbmol air/(h-ft?). Near the top of the column, when x = 0.8 we measure Emv = 0.77. Near the bottom, when x = 0.16, EMV 0.69. Equilibrium data are given in Table 2-7. a. Calculate ka and ka. b.
