question

A toluene -xylenemixture is fractionated in a bubble-cap column. Approximate the gas-phase mass transfer coefficient. The following pertinent data are given: G_g= vaporflowrate= 23.6kgmole/hr G_l= liquidflowrate= 17.84kgmole/hr M_g = average molecular weight of gas = 93.2 kg/kgmole M_l= average molecular weight of liquid = 93.8 kg/kgmole \rho_l= average density of liquid = 778.4 kg/m^3 t = average column temperature = 113.0°C p = average column pressure = 1 atm. \omega_l0 = liquid velocity at entrance to column = 0.10 m/sec D = inside diameter of column = 680 mm W = weir height above the plate = 65 mm H = weir height above the slots = 30 mm d = outside cap diameter = 85 mm n = number of caps on the column diameter perpendicular to thedirection of liquid flow on the plate = 5 h = liquid head over the weir = 8.1 mm
