6-6. An adsorption bed 0.80 in depth and 1.4 m in cross-sectional area operates at 40C and with an inlet air stream pressure of 1.2 bars. The mass flow rate of air is 4 kg/min and the concentration of the pollutant in the inlet air stream is 0.0030 kg/m. The values of a and in the Freundlich-type equation for equilibrium concentrations C and Xsat are 80 kg/m and 1.8, respectively. The bulk density of the adsorbent is 400 kg/m, and the mass transfer coefficient K has a value of 25 s-. On the basis of these data: (a) determine the thickness of the of the adsorption wave, in meters; (b) determine the velocity of the adsorption wave, in meters per second; and (c) determine the time of breakthrough, in seconds. (d) Prepare a plot of C/C,in versus (x-x). Use C/Cgin values of 0.01, 0.02, 0.05, 0.10, 0.30, 0.50, 0.80, 0.90, 0.95, 0.98, and 0.99. C C in to bo rogonorated with gotuunot
