CHAPTER 7

DIFFUSION

PROBLEM SOLUTIONS

7.6 The purification of hydrogen gas by diffusion through a palladium sheet was discussed in Section

7.3. Compute the number of kilograms of hydrogen that pass per hour through a 5-mm-thick sheet

of palladium having an area of 0.25 m2 at 500C. Assume a diffusion coefficient of 1.0 108 m2/s, that the concentrations at the high- and low-pressure sides of the plate are 2.4 and 0.6 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.

Solution

This problem calls for the mass of hydrogen, per hour, that diffuses through a Pd sheet. It first becomes necessary to employ both Equations 7.1a and 7.2. Combining these expressions and solving for the mass yields 3 8 2 2 3
