Membrane SeparationMembrane separation of gases is a growing field of operations for chemical engineers. The applications include primarily nitrogen from air, hydrogen recovery and upgrading, carbon dioxide removal and vent stream cleanup. This experiment illustrates a "classical" application of this growing field, the separation of air into oxygen-rich and nitrogen-rich streams. It also demonstrates that this seemingly straightforward process is complex and difficult to model. This experiment consists of a PRISM Membrane Separation unit that facilitates sampling of the oxygen content of permeate streams collectively or from individual separation tubes. In addition, the oxygen content and flowrate of the non-permeate stream may be measured thereby allowing the steady-state mass balances to be calculated. Analysis and presentation of these data provide information about the performance of the separation unit. |
