H1.* In Section 17.3.3 the following statement appears, “Geankoplis (2003) solves the multicomponent permeator system by a different method but the results are identical.” Solve Example 13.5-1 in Geankoplis (2003) using the method in Section 17.3.3 with a spreadsheet and show that the results agree with Geankoplis’ solution.
H2. Repeat Problem 17.D2, except do it as a cross-flow system on a spreadsheet.
a. Find solution for N = 1, which is the perfectly mixed answer.
b. Find solution for N = 1000, which is the cross-flow answer.
H3. A countercurrent membrane module with a poly(dimethylsiloxane) membrane operates at 35°C to separate air (assume air is 20.9% oxygen and 79.1% nitrogen). We want a permeate product that is ...
