A1. Membrane systems are rate processes and flash distillation is an equilibrium process. Explain why the solution methods are so similar for well-mixed membrane separators and flash distillation.
A2. How would you use the counter-current spreadsheet program in Appendix A.17.3 as a simulator instead of as a designer?
A3. What are the advantages of asymmetric membranes compared to symmetric membranes?
A4. What are the advantages of hollow-fiber membranes compared to other geometries? When would one use other geometries?
A5. In large membrane systems it is common to have membrane cascades with membranes arranged both in parallel and in series. What are the advantages of this? The arrangements after the first set of membranes ...
