A membrane is used to separate air into oxygen and nitrogen. When we say oxygen and nitrogen, we mean O and N. Ignore any trace gases like argon and carbon dioxide. A stream passes through a bundle of long straw-like fibers. Oxygen moves through the wall of the membrane, and nitrogen continues down the "straw". For every 16 moles of oxygen that pass through the wall of the membrane, 1 mole of nitrogen passes through. Assume 100 g/min of air enters the membrane. DORIN 1 A. Perform two mole balances, one for each of the components. B. What is the mass flow rate of each component in each stream? You can use a matrix approach or a block flow diagram approach. C. How do the mass flow rates change if 50% of the nitrogen-enriched stream is recycled to mix with the inlet? Use the block flow diagram approach. Solve part C separately from part B so the solution to part B is preserved. A membrane is used to separate air into oxygen and nitrogen. When we say oxygen and nitrogen, we mean O and N.
