A membrane is used for separation of gases from waste. If the feed stream contains 20% CO2 and 80% SO2 and the product contains 25% CO2 and 75% SO2. Assume that the waste stream amounts to 80% of the input stream. What is the composition of CO2 in waste stream?

A genetically-engineered strain of yeast is cultured in a bioreactor at 30⁰C for production of heterologous protein. The oxygen requirement is 80 mmol 1-1 h-I; the critical oxygen concentration is 0.004 mM. The solubility of oxygen in the fermentation broth is estimated to be 10% lower than in water due to solute effects. What is the minimum mass-transfer coefficient necessary to sustain this culture if the reactor is sparged with air at approximately 1 atm pressure ?
